GoPro: Wingsuit Flight Through 2 Meter Cave - Uli Emanuele
• GoPro: Wingsuit Flight...
I really don't see the point of running a grinder without the guard.. Not even for safety, it's just so much more comfortable to not have sparks setting your clothes on fire..
This is so true. I use a 5 inch grinder all the time in my job with a cutoff wheel fitted, and would never run it without guard.
Yeah, I'm a trade boilermaker for 25 years, there is only 1 in a thousand operations that need the guard removed, damn foolish to not use it plus it keeps the sparks away...
@@traxxasLOVR you should get someone to teach you to use it properly...
There are situations where you need to take the guard off. The problem is for legal reasons guards are as permanently mounted as manufacturers can make them. So when people need to take guards off they leave them off even when they shouldn't
Just grind away from yourself dumb dumb
I had my whole head cut off with one of those deadly cut off wheels. I was cutting some spider Webb's off the walls in my garage when the wheel disintegrated and next thing I remember was looking up at myself from the floor. Took the doctors 4 days to reattach my head. True story.
Lmao
Fake news😂
4 days? It took my doctors 2 days
Lead CNN reporter right here XD
It cut your head off.... And now you can't reproduce lol
Day to day uncontrollable hazards you can't reasonably avoid is one thing. Natural selection for complete stupidity is another. Every person that has lost a finger, eye or their life has sounded like this guy. I have accepted long ago that the job I love may kill me instantly or over time but I still keep guards on my tools and wear safety protection.
I understand, as many I'm sure do, understand the required safety at work and wore my safety glasses all the time. But we all should remember that accidents happen at home too, and not just when you are anticipating the danger. I put a wire through, yes through, my eye working on a piece of furniture because I let my guard down and didn't have safety glasses on. Now I remind my students to think critically about the adage, "what could possibly go wrong?" Yes, what COULD possible go wrong!
Why work without a guard , when 99.9 times out of 100 it's not in the way , and it funnels the sparks away
Nirvana NeverDies i would say leave it on unless you can't do the job with it on
Nirvana NeverDies you are correct with the cars, but i saw a bloke hit in the face with a nine inch grinder with a guard and he had to have plastic surgery
@@bigears4426 and that 0.01% of job that you can't do with a guard probably is better fitting for some another tool.
Haven't ground anything under a car huh?
Can you do Grindr safety next?
lol
No glove no love!
Ha gayyyyyy

Bobby: mom I cut my finger off with the grinder
Mom: tis but a flesh wound
In the subtitles it says "Grindr" instead of grinder.
BTW: I lost my hearing thanks to power tools, a grinder was one of them.
Screaming Birb
dammit bobby
Bobby: Dad, I cut my finger off with the grinder!
Dad: You better not have gotten any blood in the motor! Here, cover the cut with some duct tape. Don't worry it's a long ways from your heart; now go play with the drill press.
@@RenzitoARG Did you not know hearing protection was a thing?
@@Logic44 in a lot of workplaces you're not allowed to wear hearing protection because it's against health and safety regs. It's considered dangerous to not be able to hear someone call out. Obviously if you're continuously using something like a grinder on your own then you should, but if you're grinding, then walking to measure, then sawing, then working on a vice, etc, it's against regs to be wearing hearing protection if there's another labourer in the same room. Of course, what you do in your own privacy is your own business. Personally I think Health and Stupidity is for morons, but hey, we live in the age of the moron.
I've been riding motorcycles for about 16 years. During the first 3 years, I rode aggressively, wearing a lot of gear, had a few major and minor crashes and close calls, and gained a lot of experience with about a million safety issues. Now these are pretty clear and apparent to me, so I stopped having crashes or close calls and cut back on some of the gear. I would never tell a new rider, who may or may not be remotely like me in capability or thought process, not to worry so much, and just accept the risk to life and limb. That would be the worst thing I could do. You have experience; you know about pinching, counter weighting, behavior of the tool and jig, posture, etc. Good for you -- not good for your newbie victims. You do them no service, unlike my 8th grade shop teacher, who taught 25% technique and 75% safety because he knew his audience.
thanks for mentioning this. i too have been a riding since i was 16. I would never recomend someone riding a motorcycle without at least the helmet and a pair of leather shoes. I have one grinder disc explode on my face when i was in college. telling a person to not use the safety guard is like telling a new rider not to worry or wear a helmet.
He's not prescribing that newbies use their disk just like he's doing in this video. He's trying to teach people to actually think. It's weird to me that you somehow watched this whole video and came away with the message that newbies should be haphazard and careless. Obviously his primary audience is people who are ALREADY researching how to be safe with an angle grinder! We are the people who are spending (probably too much) time trying to look up everything that could possibly go wrong because we're scared and trying to avoid any possible disaster. For me this video was very comforting. It in no way encouraged me to go be careless or think I can act like a pro but it did at least help me stop visualizing my self cutting myself to death in a million horrible ways doing my first little tiny metal-cutting project.
~A Newbie
@@ifyouloveChristyouwillobeyhim He clarifies his priorities early on in the video when he states that you might cut off a finger, but what are you gonna do, it's a learning experience, no big deal. The idea of skipping safety glasses and telling thousands of people of all ages and experiences not to worry, don't be a wuss, is mind boggling.
@@curtmcd I don't think you read my comment very carefully. . . .
And by the way thank you for defending him in mentioning what he said at the beginning about cutting off a finger, etc. It's just what our society in general needs to hear, we who have an irrational fear of anything bad happening, ever, to realize that accidents happen when serious people are getting stuff done, a losing a small piece of yourself is not something to make you petrified. Now if this were a video on wrecking balls or electric lines strong enough to kill an elephant, I guess one might be a little disturbed if the man was telling you, "Don't worry, you might get crushed and die but it's no big deal."
Well, I'm checking out! It's been a good convo, but I reckon I'm wasting my time if you're only half-skimming my replies instead of reading them thoughtfully. :p No hard feelings.
@@ifyouloveChristyouwillobeyhim Once you're experienced, you know what optimizations you can safely get away with. That will come naturally with time, and is not something you need to be told. But if you're not sure about something, watching a video telling you not to worry can only hurt. You should NOT be comfortable. There ARE going to be mistakes, and it's best they all be low consequence. Cutting off a finger or losing an eye is NOT low consequence.
Using a 300mm cutting disk on a 3500w angle grinder, cutting up a stainless tank (I needed breathing air via a mask due to the gasses released when cutting this) the disk exploded, and half the disk got stuck in the welding mask with fresh air supply I was wearing. The angle grinder had the safety shield in place.
If you ever injure yourself with an angle grinder, I hope the insurance company sees this video.
Would have been a pretty weird moment getting back to the shop to ask for a new mask while having the other one with half a disk in there...
To be fair 300mm at 3.5kw is quite a bit bigger than most people will ever use. His point does stand that people are becoming unreasonably afraid of everything and for anything you do with an average 1kw grinder safety goggles are sufficient protection. Though no guard does make me uncomfortable given my experience with rotary tool cutoff disks(
The kind of person who would leave a comment like this is fittingly the kind of person whose first thought is insurance companies.
300mm and 3500w sounds quite a bit bigger with more energy than these little machines
"In the next episode, Doug explains why he removed the safety catch from his AR-15, and demonstrates just how safe the gun range can be when mildly inebriated"
Spoken like a true Inebriati. I wholeheartedly approve.
And don't forget the hot loads. The main reason to use a good press is to overfill the cartridge case and ram pistol powder down the neck as deep as you can crush it in. "Got 5,000fps on my first shot, let's see how the second one does..........."
You guys shoot your AR's sober?
During med school i had the fortune to work with one of the few hand reconstruction surgeons our country has. And let me tell you that power tool injuries (especially grinders) won`t result in only a lost finger. Sure these injuries don`t threaten your life if properly taken care of. But what the inevitable outcome will be is a severe dysfunction of the hand, partial loss of prehensile function (meaning you can`t grab things with it) and almost always complete loss of fine motor function. Considering that most times (80% ) the injured hand is the primary hand this results in a sever handicap and complete inability of said patient to continue working leading to loss of income and severe social distress. So no grinder injuries won`t likely kill you they`l just ruin your life.
Deceneu
Do you have details of what exactly happened/went wrong please?
Yes agreed callous disregard for reasonable safety reccommended here concerns me. Here are two people from a study that nearly died from grinder injury: www.ncbi.nlm.nih.gov/pmc/articles/PMC3137829/
Sampling bias.
The majority of grinder accidents never show up because they are trivial. Minor burns. Minor abrasions.
You saw the worst cases because it is the worst cases who go to the hospital. As every grinder accident you see is serious, you wrongly conclude that grinder injuries are generally serious when they aren't.
@@forestdenizen6497 never said all grinding accidents are serious. However the potential for seriousness, demands the saftey gaurds that people put in place.
@welderfabrod that could be, and i dont doubt there is fear mongering. I have had small grinding discs off of dremels come back to my head so i dont see why a grider wiith a cut off wheel and no guard couldnt. In our shop we dont use guards because they get in the way but we also make everyone wear full shields over their faces.
"He might lose a finger... it's OK!" Oh, geeze!
🤣🤣🤣🤣🤣 he'll grow another one
😅just another day
"he might lose a finger, we need these experiences to grow up in life so it's ok" 😂
Most likely injury with a grinder is that you'll damage your hearing
What? Speak up!
Or lungs, breathing in that delicious disc dust
Idiot. If your not wearing safety gear, you'll lose an eye before you lose your hearing.... I have lots of scars from grinders, still have great hearing. Almost lost a finger once, cut off wheel bound in the curf, and grinder ripped itself out of my hands and ran through a knuckle on the way out, but I still hear good. A grinder can cut through gloves, debris can ricochet off stuff and get into your eyes despite glasses. Takes years to damage hearing, but it only takes one bad decision to lose an eye....
What? What?
@@JoshuaZiesmer
It takes hours (maybe minutes) to have significant hearing damage using a typical angle grinder without hearing protection. Also best to have something between the fury of sparks, metal and abrasives and your eyeballs as well.
"That's called a clue"... I love it!
Good shout
...priceless!
I lost it haha
😂

In my 20 years of working in anaesthetics and critical care, I have had several hundred patients with traumatic injuries caused by power tool's. The majority were from not operating the equipment correctly, using the tool for the wrong application, inexperience, complacency, doing stupid crap and freak accidents. Circular saws are the most common, one guy lodged the guard back on a circular saw while off balance cutting timber above his head. The saw kicked back and sliced his face open from his forehead, skipped over his eye and caught his cheek and sliced across his face through his lips, chin and onto his chest and hand. Half his face was hanging off, but he was incredibly lucky to have missed major arteries and his eye.
Another guy was cutting a little an annoying bit of wood with a jigsaw on the wall, he hit a nail which broke a piece of the blade which flew off and severed his carotid artery and he bleed out straight away in front of his family, freak accident. Another guy walked to his back door and was scraping the scraps off his dinner plate for his dog's, something he did every night. He somehow tripped and fell down a few steps breaking the plate which severed an artery and he bleed out in minutes. Freak accident.
If you are smart and understand what you can and can't do you and don't become complacent or stupid you will be fine 99•9 percent of the time, but sometimes freak accidents happen no matter how careful you are.
"There's things in life that are dangerous". Yeah, and there's things in life that reduce unnecessary danger. Take advantage of them.
99% of the comments have completely missed the point of the video. I think when it's been explained *this clearly* and people *still* don't understand, then it's better just to walk away and leave them to their own devices. Unfortunately these people don't accept that and then feel the need to interfere with the lives of others by telling them what they must do against their will. This videoer isn't like that. He's not telling you what you have to do.
@@aaronmicalowe I disagree, this cowboy is perpetuating the bullshit idea that real men don't need to bother with safety. Its a particularly poisonous idea where it relates to the young and inexperienced trying to look hard.
The guard serves three main purposes and I wouldn't be without any of them:
1. It deflects sparks and debris that would otherwise impact you causing holes in your clothes or a rash on your skin
2. Grinders grab and when they do they can jump back at you with some force, speak for your self but I'd prefer to be hit by the guard rather than the disk
3. Disks do shatter and when they do you don't want that anywhere near you.
If you find a job which requires the guard to be removed then you have found a job which requires a different approach or even a different tool.
One final point this idiot implies its his own choice if he amputates his finger, yet I've no doubt he expects the emergency services to rush to his aid if he does. Even under the hyper capitalist American health care system he will be relying on the pooled insurance premiums of thousands to fund his treatment!
@@lendoggtheking well, you're welcome to your opinion but you have no right to force it on others. Like I said, he's not telling anyone what they have to do. And it's got nothing to do with real men. That's a concept you have injected and isn't in the video. People are projecting their own negative bullshit - and that's what they see. Their own bullshit coming back at them.
@@aaronmicalowe I work in engineering and have found a very strong correlation between people who style themselves as "real men" and a disdain for safety features, everyone in the industry knows of that type.
His opinion is effecting others because he has chosen to make a video and post it to TH-cam. It emboldens people who believe that safety features are a waste of time, I am occasionally forced to work with such people, they are a danger to both themselves and others including myself!
@@lendoggtheking good for you that you have that projection. That doesn't mean everybody else has to have the same view. At no point does this guy even try to make it sound about gender, so for me that's a total non-argument.
Non-reinforced cut off wheels explode all the time, but are still useful. Wire wheels shed as well. For me, safety glasses always, face shield as needed. Hearing protection is another thing as the damage is not acute, but additive over time. Same thing with protecting your lungs.
The little dremel ones are the worst because you've usually got it right in your face anyway just to see what you're doing, taken a few to the face, always wear glasses using those
I dont screw with wire wheels anymore without at least glasses. I dont like wearing safety stuff but a loose wire hitting me pointy side out 1/4 inch from my eyeball was lesson enough for me.
@@markdoumert4840 wire wheels. If it ain't in your eye it's everywhere else. Took me a month to finally get rid of all the brushes on my clothes after polishing 4 buildings worth of fences
@@CSkwirl I have those breaking regularly even when just trying to screw them on the dang thing. If you get them spinning they may even break looking at them.
Good thing is they kind of disintegrate into dust, nothing that really goes ballistic for more than an inch.
I've done alot of live edge wood working with an angle grinder and those fucking wires will stick into you like a dart! It especially sucks when they hit your fingers and you feel it to the bone! Use a guard or some kind of protection!
ITS JUST CONSIDERED OKAY TO LOSE A FINGER
Not hard to put one back on
@@spacedoutcowboy5211 theres going to be a few millimeters of finger missing and the rest a bit shreddrd
@@Hwhiskeygames2 nah, if anything it'll grow few milimeters longer
@@spacedoutcowboy5211 And then you have permnant nerve damage
Like he said some people need to learn the hard way 😂
Dude, I appreciate the message you’re pushing, but that is the most insane test of a grinder I’ve ever seen. Do not abuse a cut off wheel like that ever anyone. I use a grinder near every day and that absolutely had me on the edge of the toilet the whole way through. People really do catch critical breakages of grinding wheels, just because you couldn’t injury yourself or your friend in your garage doesn’t mean it’s absolutely false. Take it from one who’s caught a wheel in the chest and had the whole device torque itself out of their hands multiple times behind them faster than they can blink, do not do sketchy shit with them ever, enough can go wrong using them proper... and jobs are never following politenesses.
Yeah, I mean the worst thing that could happen is that you die, but that's just a part of the learning experience. Don't be so afraid of dying!
I think I died from disk-grinders about 3 or 4 times in my youth. It always sucked when it happened, but it sure taught me a lot!
Grinders don’t kill people, people kill people.
Wow, that's deep bro...
No one needs a high powered grinder.
We need "Grinder Control" in this country!
We need common sense grinder control and universal backing disks.
@@heyyou5189 - That's right. Everyone who wants to use a grinder in public needs to take a 10 hour class and 5 hours of supervised onsite use before they can be a licensed grinder operator.
You had one job!!...Meanwhile the cat is gonna be eating grinder disk for the next few days
I’m speechless. That’s some of the craziest Sh*t I’ve seen with a grinder.
Don’t try this at home!!!
As a stonemason, used grinders full time. Not hurt myself, but seen and heard from friends about life threatening accidents that they had. Eg, cutting steel roofing on gutter line. Put running grinder on his leg while looking at what he just done. Grinder rotated, cut BIG hunk out of his thigh, through artery. Threw grinder, sruck small finger up artery, picked up lump of flesh, climbed down, drove to hospital. That is how he is. Lived. They are good tools, but deserve respect.
54 years on the job since I was 14 working as an apprentice electrician. You correct in that your safety is your responsibility. If you are working alone and hurt yourself you are to blame. I have worked in a dozen shops. Welding, grinding, running machine tools, cutting torches, and yes hand held grinders. I have never been hit by a shattered cut off wheel.
I have had one shatter and stick itself in a beam over the tablesaw it was mounted on.
I took a guy, named Rex, to the doctor to get stitches when a paper sanding disc shredded and burried a arrow shaped chunk in his forearm. He was lucky it cut into the muscle instead of tendons or arteries. The stitches looked manly.
What if you sren't working alone. Many shops have benches or fixtures with people working in close proximity. I welded display fixtures on one side of a bench. The other guy on the bench welded at the same time. While I'm cutting or grinding if the blade breaks the pieces won't always fly off harmessly to the corner of the shop. The guy next to me, across the bench from me, or just walking through catches part of the blade. Let's hope they are happy with a few manly stitches.
Have you ever checked the RPM rating on your blades?
Your battery operated Dewalt does 9000 RPM. Amazon sells an air sander that does 18000 RPM. www.amazon.com/Central-Pneumatic-High-Speed-Sander/dp/B00791ZK8U
The same wheels fit both. Flap wheels for grinders and sanders have multiple speed ratings. Put the wrong wheel on your sander and the pieces will fly the length of the welding shop at Demmer Corp, in Lansing. I was there. The sander doesn't come with a guard. See the story about Rex above.
If you don't want to use guards, wear PPE, or pay attention to the speed ratings on your tools it is okay by me. Darwin built his reputation on those situations. Just don't convince that kid who's watching their hero on their favorite channel tell them to do something demonstrably stupid. Chances are they won't ever work for me. If they do it won't be for long. My companies are my responsibility. If an employee gets hurt while working for me, no matter how stupid their actions, it is my insurance premium that goes up. It is my assets that are in jeopardy.
So when the kids go to work they should know that your decisions are yours. If they try to act unsafely on the job they can expect to be fired. I hope I catch them before someone else gets some manly scarring.
I'm not reading all that but i'm glad for you / sorry it happened

Phenomenally written, enlightening comment.

3:30 I disagree, I still have the hole in my wall from when one disc blew up on me. Those pieces have a lot more power than you would think
The one word you used that sums up safety, not just for grinders, but for all power tools. Respect. Respect your tools, know what they can do, and for the most part you're already there with safety.
If someone dies from using a grinder, they probably weren't meant for this world..
ive heard guys akmost bleeding out from skill saw cuts to the leg
@@whit6282 that has teeth...
AKAtheA hot cut off wheel goes in like butter.....
@@whit6282 but still...no teeth...big diference, especially if you are stalling the motor. Abrasive wheel won't chew through flesh so well once it slows down, teethed blades will keep biting and ripping until they come to a complete stop.
I've been hurt but i don't see how it could kill you. I've touched my skin with a flap disk (by accident) and it barely left a mark
I was a telco employee for 28 years. We kept trophies of safety saves. One was a glasses with a screw thru the lens 1/4 in. I knew the guy personally. So there are valid cases of saves from safety equipment. Just be sensible like he says
That's how we learn
"Jimmy"
"Jimmy!"
Oh sh*t Jimmy's dead well I guess he learnt from that mistake
LMAO 😂
He for sure won't make that mistake again.
i love that this video is just this guy proving the safety of grinders by doing all the things you're not meant to do with them for you
No hearing protection? No gloves? No face shield? No particle mask? Wheel loose on spindle? Safety guards removed from grinder?.. this guy is a poster child of how not to use your grinder lmao... most of that stuff would get you fired at places I've worked...
Because employers don't want idiots doing stupid stuff
face shield? mask? guards? your quoting out of a osha book with no practical experiences in the field. on a job site you very rarely ever have access to even half of what 'osha' wants from you and even if you do, the added time and effort or even the sheer size of safety equipment make the job more difficult or impossible to accomplish. maybe in a warehouse setting or some type of ultra high end industrial manufacturing plant you could get to osha level but certainly not out in the field.
i think the point is he had none of that, used the grinder with broken disks in terrible forms and came out the other side perfectly fine
@@INCC74656I I worked as a union welder for a while, I'm pretty sure I know what I'm talking about when it comes to grinders and their use professionally... we literally had meetings about such topics and would get sternly reprimanded for misusing tools, if seen by a supervisor or general contractor, or inspector...
@@toadamine im sure there were meetings, there are always meetings. whats on paper never translates to whats on the ground in my experience however. a sizeable chunk is lip service. job done is #1, job done in budget is #2, osha fall some where behind lunch break requirements.
Mate i don't even know what to say... but don't encourage nubes. I work with grinders every other day and Iv had and seen injuries that warrant keeping the guard on. Don't mean to be the health and safety police but people should learn with the gard on
having a guard on just allows for people to be stupid with the tool.
I absolutely agree. If it can be done with the guard on, do it. I only remove the guard if it is absolutely necessary to get in a tight spot, and that has only happened a handful of times over the last ten years for me.
Personally, I'd try it with the guard on, but if I understood the risks and the guard was getting in the way, I'd remove it. Getting frustrated with obstructive safety equipment is as, if not more, dangerous than faulty equipment.
I support Natural Selection.
How are you gonna fit a 6" cut off wheel on a 4" grinder if you use the guard. Bottom line wear ppe and dont be stupid. And ALWAYS USE THE HANDLE.
My grandpa never fails to talk about how a grinder disk broke on his coleague once and he ended up with a chunk of the disk embedded in his face.
You need to lose a finger to grow up in life.
Geez, no
Lmao seriously I thought the same he acts like it's getting a tattoo or ear piercing.
Hes obviously not very smart. But thinks others arent for using extra safety precautions. The people I've seen get injured are usually the ones disregarding basic safety
He said some people if your not one of them be happy about that.

You're crazy buddy I'm gonna keep wearing my face shield when I use a cutoff wheel. To each their own.

What’s really scary is the dust you’re inhaling while grinding/cutting

@@jonanderson5137 Given how fast it cuts into metal it's clear how fast it'll cut into our soft bodies.
Yeah I had a job grinding old cracked welds out of aluminum back when I was 19 or so. No one ever mentioned any link to Alzheimer's back then. It's ok though, I'll forget all about having that job soon.
What about ear protection also... I guess some people don't want to talk to their grandchildren these days.
When I was a child my neighbor cut his hands and arms, slit his mouth opening up to the back of his cheek and cut into his jaw and deep into several of his own teeth in the back of his mouth with a locked grinder because he dropped it from above his head while cutting.
He had a lot of ticks where he would jerk his head hard to the side while sniffing, so he looked pretty brutal before he got cosmetic surgery to hide the scars.
yikes
Did he try to catch it with his mouth??
It fell into his mouth whilst running with the lock on? Lucky it didn't cut his head off
The picture of those safety glasses with the blade stuck in it is real. That cracking around where the blade entered the glasses is from hard impact blowing the plastic out into his face. Those little chips wouldn't be there otherwise, and it would be next to impossible to fake them and make it look realistic. Not to mention nobody would waste their time on it.
Table saws and jointers scare the shit out of me... I've seen a 2x4 go straight through a shop door and my shop teacher cut his thumb off on it too, dado blades are just insane, and I don't even want to imagine what an injury on the jointer would look like.
The way he is confident, it is like me playing with electrical wires,when everyone is afraid.🤣🤣🤣🤣
In 1975 the next door neighbours son who was a heavey equipment mechanic had a 9 inch grinding disc explode, he was wearing goggles but that did not stop him getting so badly injured he ended up in hospital for a week. I saw him shortly after that with a huge scar across his face and nose going into the corner of his right eye. Apparently when the disc ruptured it nearly cut his nose off. The modern cutting disc may be lighter but back then the grinding discs were a quarter inch thick and the fiber reinforcing was not as strong as it is today, grinding discs are still around a quarter inch thick and therefore carry much more kinetic energy than a cutting disc.
But... had his face simply not been in the plane of rotation, it wouldn't have gone in his face! It's simple physics.
@@TonyRule As I understood it at the time he was grinding or cutting something underneath a truck where it can be very difficult to position yourself such that you are out of the plane of the disc and in any case in such confined areas there is also the probability of ricochets.
@@Equiluxe1 Then IMO he shouldn't have attempted it. But anyway, as pointed out, the energy in a section of cutting disk is very low as it is so light.
@@TonyRule not the old ones back in the 70's they were an eighth of an inch thick had less reinforcing and were rather brittle as well. I always used to do the ring test on them and if they did not ring I did not use them, modern ones dont ring if you tap them while supported via the hole in the middle. Any one who does not wear PPE use the guard provided by the manufacturers and take suitable precautions in the use of grinding and cutting equipment is both reckless with their own and others safety.
The old 9 inch is renowned for causing some extreme violence
I once had an accident with a grinder. The wheel exploded straight into me. Nothing serious just hurt a bit from the impact. And i've learned my lesson, never use cut off wheels for grinding.
This video so inspirational- AND I HAVE SUBSCRIBED !!!
Why is this in my recommended.
Because you didn't Grew up well. Cut one of your finger, learn and grow up.
Grinders don't kill people, people kill grinders. Lol!
@Jason Lee It is in Denmark :)
@Jason Lee you just come visit me, I have a few grinders I need to check against flesh :)
@Jason Lee scratch some scratches
Soren Hansen lol!
@Jason Lee its not that hard to kill a grinder. hold it in the wrong way and it will let the smoke out in just a few minutes of use.
My father cut his arm with a grinder , complications and age ... week later he was dead . A 3/8 grinder spins at around 200 revs per second , amazing forces at work . I work with a grinder a lot , but dont ever think its not a deadly tool , its as bad as a chainsaw or worse with the possibility of those carbon blades coming apart and becoming shrapnel .
I have not had a whole disc fail, but sections from the edge fly off.
Wear goggles, wear hearing protection, use a dust mask, particularly with aluminium and use the guard.
This guy's a typical shop know it all.
My line manager lost an eye from a steel filling that got infected and to say grinder wheels don't fail is bull.
We have a failure about twice a year in a shop of 8 guys. Why? Because they get hit or dropped and the damage isn't always as visible as the guy showed here.
On track with the Stihl saws, they break discs weekly. Usually just a chunk out the edge. Noone stands in front of the guy cutting and the guard protects the guy on the back.
“All it’s gonna do is cause minor flesh ripping and tearing, and you may lose a finger or two, but you don’t need all your fingers, just enough to operate the grinder. So to recap, not dangerous, don’t listen to safety, and just have fun with your power tools.” - this guy
Hi Mom! : )
Got 11 staples in my arm and 5 in my chest from one of these things, got a little to comfortable with it. They'll mess you up if you aint careful. Now ik how to use one the hard way.
what happened?
@@DerKrawallkeks kicked back due to wrong cutting angle, and grabbed my glove and tore me up. Hit 2 arteries in my arm, real bad cut into the muscle wall of my chest. Almost hit my liver. They are no joke. Treat them well.
zenith0000 Holy smokes bud, glad you're still with us! Had some experiences with these things but nothing close to what you describe, just cuts on hands etc.
@@CentralArkansasHomesteadandOff thanks for sharing your experience with me!
@@peteschubel1804 thanks dude. Itll be 1 year here in a couple weeks. Happened on 2-11-18. Still got 2 ugly scars and not much for feeling on the underside of my right fore arm.
You just said the things I've been saying to some of my friends for years! I guess thats why I spend my free time making cool stuff, and they watch a lot of TV. ;)
I died 3 times looking at a grinder without a gaurd on it. It wasn't even plugged in.
Lol
its battery powered
😂🤣😂🤣😂🤣
A very very thank you to you ,, last time (1 year ago when i held an angle grinder in my dads workshop I was fed with those stories and I wasnt even able to turn it on
For more than 3- 4 mins , constantly turning it on and off ,, today I watched your video and went there and without any fear and with visions of what all you did in video to prove proper handling wont cause blade to explode ,, I just came after cutting a knife shape from a sheet metal ,, started with a bar and then went on to sheet metal .. . Thankyou very much ,, adios
" It's ok Bobby, you have 7 more fingers and two thumbs". LOL keep up the great work. Peace my friend.
Wood workers are far more likely to lose fingers than metal workers. My dad took me into his works one day (I was about 6) and his manager in the office didn't have a full finger on either hand, when I mentioned it too him later he said, 'that is why he works in the office'.
Sparks=clue....got it.
Also fire. If it's on fire, and it shouldn't be, you did something wrong.
If grinding wheel stuck - grinder jumps in other direction, opposite of sparks.
Ive been collecting sparks for years, still cant find any damn treasure
I love the shower of hot metal in my face. Reminds me of all the times hot brass would go down my shirt and touch me in ways nobody else can. Gives me chills just thinking about it.
Subbed because youre pretty funny and you edit well. Great work!
Thank you! Telling us the actual risks in addition to what's overkill. I appreciate it.
Always like hearing your perspective Doug. Situational awareness and common sense.
The guys who circumvent safety devices are all the same, It's some type of bravado issue for them, as if having a milky eye, missing finger, or black lung is just part of being a man. They are all over the place, guys who shim circular saw guards open, guy who remove chutes from lawn mowers, guys who take deflectors off grinders. You are not smarter than the engineer who designed the tool you are using. Safety is not a common sense issue, stuff fails, discs shatter, people die and fate cares not one bit if you were the best or worst of operators. Protect your Eyes. Protect your Lungs. Protect your Ears. Disrespect the tool and safety at your peril.
stfu
Uh, nah
You are 100% correct. The guy who made the video is a complete idiot who shouldn’t be close to a workshop.
But worse I think is the morons agreeing with his very poor practice.
well said.
I agree, the guard is not even necessarily to protect you from yourself, its to protect you from a variety of factors.
Like, theres a chance a grinding disk may be cracked because someone dropped the grinder or a manufacturing defect.
Just because it isn't guaranteed to hit you when it shatters there is still a chance it might hit your or someone else.
What if you turn that thing on and it shatters the second you touch material? What if a sizeable chunk gets flung off the jobsite and hits a kid in the head?
The crap this guy is spouting would not come from anyone with an engineering degree or half a brain cell.
just simple maths lets you figure out how dangerous that grinder wheel can be:
Assuming a 180mm (7 inch) grinder at 8500 RPM:
180mm*3.141=565.38mm circumference = 0.565m
8500*0.565=4802.5 meters/minute = 80 m/s
*The surface of that grinding disk moves at 288km/h or 179 mph.*
Do you want to get hit by a quarter of a grinding disk at that speed? Do you want to take that angry fast piece of disk into your nuts?
I found some cutoff disk mass specs too (Merry Country 180 Professional Line Grinding Discs):
*180x1.6: 88g*
*180x3:
172g*
*180x6: 360g*
Kinetic energy = 1/2 * mass * velocity²
So if a quarter of the disk decided to break off you'd get, respectively
180x1.6: 0.5*0.022*80²= *70.4 Joule*
180x3: 0.5*43*80²= *137.6 Joule*
180x6: 0.5*90*80²= *288 Joule*
a .22LR has 170-300 Joule of energy.
You gotta ask yourself, do you want to risk basically shooting yourself in the hand, or the dick, or the eye with a .22LR for literally no reason other than taking the guard off for the sake of taking it off?
We could figure out exactly how much energy each part of the disk would have based on distance from the spindle and the respective mass of the area but i can't be bothered
Love the fact that he tried to make a point about the grinder wheel and the grinder was like “Nah nope, not today buddy”
Great video! Love the commentary
One year ago yesterday I was injured by a cutoff wheel. I bought a brand new grinder and a pack of discs from harbor freight and the first use the wheel exploded sending a shard into the top of my hand to the base of my thumb. (I had full hand and eye protection). I had to get 12 stitches. I lost so much blood I passed out. I came close to losing my thumb. And bleeding out. My hand still hurts to this day. Don’t buy power tools from harbor freight folks! GARBAGE!
Or just buy the grinder from harbor freight and run proper wheels on it (CGW, Norton, Sait, etc.)
or just learn how to use a grinder properly
harbor freight grinders are a ok mines going on 5 years and i make stuff like what's in my profile photo its the consumeables that are trash mate
I have a good old Makita, that machine is a dream
I’m sure it hurt like an SOB. Not to be a Debby downer but I highly doubt you passed out from blood loss, more likely just seeing that you were bleeding. Absolutely believe that you could have lost your thumb, but no where close to almost dying from the blood loss associated with it. Be safe
At work I was cutting a piece of 1 inch angle iron from underneath and just like you said it pinched the blade and kicked back into my into thigh. Cost me 24 stitches. Two days later I bought one for my garage. Lol. Some lessons are learned the hard way
Thanks for this video. I'm a woodworker but used a grinder quite a few times in my day but I never knew the limits of them or how dangerous they actually are.
Nice words at the end! You will see me back here.
Considering that 20% of all power tool injuries are from Grinders (Source:Metabo) and 80% of those injuries are to your primary hand:
1) The inevitable outcome will be is a SEVERE dysfunction of the hand.
2) Partial loss of prehensile function (meaning you can`t easily grab things with your hand anymore)
3) and almost ALWAYS complete loss of fine motor function.
What does this mean to you:
a) Complete inability to continue working
b) loss of income and
c) severe social distress.
The point: Yeah, a grinder injury may not kill you - it''ll just ruin your life.
KEEP THE GUARD ON
WEAR PROTECTIVE EQUIPMENT
Most injuries happen to new users AND those with 10+ years. i.e Inexperienced and those whose luck is running out by sheer force of numbers
(Reposting @deceneu and edit)
I use a lot of the cutoff wheels for work, they're more dangerous than you think, but I've never been injured by one. My welding hood on the other hand has a hole right where my forehead would've been. I was in a tight hole cutting a piece of pipe, I slipped, caught the wheel sideways, the wheel caught, then came apart as the grinder spun up again when I pulled back. I happened to twist the grinder inline with my face in that split second going for the off switch and half the wheel went into my hood point first. It made it through and stuck there quite well. Sometimes freak accidents happen and there's a reason I wear protection.
Thanks dude, good advice!
Great video. I feel less afraid of a grinder wheel flying into my face. I’ve already imbedded one into my thumb. Obviously I learned something from that. No loose clothing material around a grinder!!! Thanks for the lesson on balance. I think everyone needs that. 👍🏼
Good job. 👌 😊 This video definitely will increase your viewing time.
Thank you thank you thank you, at last some common sense on the internet about grinders, being an engineer on the tools for the last 25 years it was nice to see someone putting forward the logic and reality, might have been worth explaining you dont have to hang on the end of the key to tighten them up, personally I leave the nut half a turn undone and turn turn the grinder on, it nips it up nice, then I let the cut set the torque on the nut, not over tightened and best of all you can remove it without the key!! no over tightening, no fractures in the blade, just happy days of grinding... many thanks again for teaching this base line logic in a crazy world of health and safety.
This vid gives me so much of piece of mind.
My heart throbs when I use an angle grinder.
This is what I have been looking fore as a metalworksnoob, I had to watch it in full HD. Great video.
Hearing protection is something I don't see a lot of in your videos. Almost gives me second hand ringing ears when you guys hammer loose inside the hull, the echo must be immense. I thought ear muffs were very cumbersome and in the way, so I treated myself to some form fit custom earplugs about a year ago. They are fantastic. I can still hear conversation just fine, but they have a valve in them that will close when there is a sudden loud noise. I wear them all day every day at work. Don't really notice that I have them in. Super comfortable and great for my ears.
Yeah, i learnt that one from my workmate that is 10 years older than me and had to spend $10k on hearing aids so he can hear his wife and kids.
What are these ear plugs your talking about? I have a real sweet set of ear muffs that allow me to hear talking, music, etc then "close" with a loud noise. I love them, but it think ear plugs like that would be even better!
I'd be interested in knowing what earplugs those are as well.
Huh ?
This is all nice and great if it's your own tools. As someone who has to deal with shop tools and deal with people who don't respect the tools.
It's not worth the damn risk.
My health isn't worth the damn risk. like many of us here my hands, eyes, and fingers are what make me money. My house, car, and lively hood aren't fucking worth it.
what a great programme very nice there pard
Your attitude is refreshing
Make sure the sparks are going towards you (if you don't have the guard on). Otherwise, if the sparks are going away from you, the actual wheel itself is pushing the grinder towards you, and if it jams up, it may suddenly (and with great force - even a power hand drill can do this when it binds) lurch towards you. Well, it's a good way to get nasty cuts on your hands, arms, and torso...
thats myth, when a rotating object explodes, it explodes in all directions.
@@Paopao621 He didn't say anything about it exploding. If it catches, it can and will kick towards you. Can you control the kick? Sure. Do some people get lazy sometimes? Of course. Is that a reason to abvoid grinders? Maybe...if you're a bleeder.
I have had loads of discs explode on me.... And the battery ones doesn't go as fast as the corded ones... I actually prefer using the guard just to control where the sparks go and to get into them stupid awkward positions where if the disc explode will hit your face....
I've been using them for 20 years and the handful I've broke were my fault for binding or pinching them. You're your own problem, stop fighting it and stop using the left side... you big dummy.
@@manbunmyname5866 im guessing you've perfected the art angle grinder as a precision tool..
You can't fix stupid and you are truly the King of them.
It’s ok to be frightened darling. It’s normal until you learn to do something.
Best advice I’ve heard in a while
Guy at my work had a cutting wheel split his face open. Teeth and blood everywhere. He wasn’t wearing a grind shield though
mattroski007 lol *gets tackled and dragged off stage*
Later that week individual grinds himself severely, that's exactly what would happen to me if I made a video of me being a " master of grinding"
Life does have a tendency to deliver what you expect.
I like the part when that disc separated and you hear it stick the wall across the room. A friend of mine almost died when a cut off disc separated with a large piece ending up in his abdomen, he almost bled to death. The grinder he was using had the guard removed by someone previously.
I seriously doubt that was a cut off disc. And I have noticed a theme in these reports where the fault is not the user. We like to point the finger at the person who removed the guard, and not the person who choose to use the tool as they did.
Actually a great video mate. Well done
"he might loose a finger, it's okay"
I was circumcised with a grinder
I believe this lmao
You grew up well. Congrats ! 💀
I rarely operate my angle grinder because fear of injuries & getting hurt untill i watched this video.
SV Seeker ......Thank you very much for showing & telling us this.
Reminds me of what my moms reply was when a concerned teacher felt the need to confront my mom regarding how I asked if she could call the police instead of calling my parents to tell them about my bad behavior in class that day.
She simply said this... "Fear is a good thing"
First that's a batery powered grinder that I think it use a bldc motor. The starting torque is much smaller than that on a corded grinder(read about the series wound motor). Less torque=less strain on the disk at starting =less chance of breaking. Secondly it has much less then 9000 rpm when cutting.. maybe 5000 rpm. The guard is there to protect you from disk break sparks and for resting the tool with the disc touching the bench. I've heard a story where using a guard could have saved someone's life. A worker was cutting some steel using a grinder without a guard.. then a power outage happened.. the worker puts grinder on the bench forgetting to turn it off.. power comes back.. worker rush to stop the grinder.. but grinder spins and falls from the bench on the floor.. disk brakes and a pice of it hits worker in throat cutting blood vessel.. worker bleeds to death. Be safe! Never use a grinder without a guard!
Yes and just always unplug the damn thing.
20v Max Dewalt he is using is a 9000 rpm brushless motor, with a soft start, electric brake and auto stop if pinched. It's a joy to use, but needs 6ah batteries if you're going to grind with it. Highly recommended.
As an experience user of this tool, here's some advice: never force the abrasive disc into the work or an accident is likely to ensue. If you drop a disc on a concrete floor, throw it away. Same with a grinding wheel. If it is dropped on the floor, chuck it. It might have a hairline crack in it as a result and can and will explode once spun up to thousands of rpms. And remember, everything is known in the state of CA to cause birth defects and cancer because proposition 65 says so.
For all my life "26yr old" ive been scared of grinders. I will never be again bcuz of your video ! This is so much more instructive than every safety video on the web ! Wow !
definitely showing this at the next safety meeting, Thanks!
I had two new cutt off wheels explode in a row one day. No side pressure, correct disk size, correct disk speed. Seems contrary to the experience of most people. Has me a lot less confident with the angle grinder.
Yeah but have you tried just not making mistakes? Because according to the moron in the video, it's as simple as that folks.
I think you might want to check the brand of disk or maybe see what kind of crazy grinder your using. that is very unusual
haven’t broken a wheel in my 5 years. maybe my time is coming. who knows.
"their face in the line of rotation, all those sparks hitting you in the face, that is called a clue".. friends that is priceless !!!
thanks bud this vid removed some fears
G'day Doug
I just love it when you go off on a tangent... you would do great as a " stand up" comic , but please don't give up your day job cause I love SV SEEKER videos too .... can't wait for your next rant .
Much respect from
