Thanks for the safety tips. Of all the tools in the shop, I have injured myself more with an angle grinder than anything, and I try to be safe. A few things I've learned: 1) After grinding a piece of steel, it gets very hot -- don't forget it. 2) A grinding wheel will cut through your skin a lot faster than metal -- it will take time to heal. 3) Wire wheels usually throw off wires at high speed -- they penetrate easily through cloth, so think how much easier they will go into your eye. 4) Don't think it will make you look like a pro if you take the guard off.
@@ve2jgs Greg, the angle grinder is a very useful tool after welding and during other metalworking operations. Kind of like fire, you use it but you always respect it. Grinders are like any other power tool in the sense that they have no conscience, and can do damage to the operator just as quickly they can to the part being ground. I use grinders often, but I'm always trying to be aware.
Wow. This is a how-to video of precision and perfection. There isn't a single word wasted yet the information is abundant, to the point, and all in order. There are no jump-cuts, no pauses, no annoying background music. I played it repeatedly to learn about this tool but I also played it to appreciate the first rate job you did. Thank you.
Great tip to pass on-zip tie your wheel wrench to the plug-end of a corded grinder. Not only will you never lose your key, you’ll never forget to unplug the power when changing out a disc. (Can’t remember where I picked this up, but thanks to original source! Works like a charm.) Tim, you do a fantastic job and your videos are my favs. I’ve learned so much from your channel. 🙏
A simple tip, a massive difference. Not only for the safety issues but when you have your mind focus on doing something there is no biggest disruption of your thought process than looking for the damn wrench, which is always out of place or missing. It also works for the drill key.
@@jonfisher9214Nothing, you just use your hands (preferably with gloves) to pull the disc (counter clockwise) while holding the button with the thumb of the other hand. Then when you change the disc, tighten the nut with your hand as much as you can and finish the tightening by pulling the disc (clockwise) with your hand. I worked in trades for years and you will almost never see someone on construction site using the wrench.
Nice video. I recently started using an angle grinder for cutting angle steel, and for removing old paint, primer & rust from a steel I beam bridge. We found that the Bauer Surface Conditioning Tool with the 40 Grit Stripping Drum was superb at removing a large swath right down to the bare metal, but we needed angle grinders with both the knotted & wire cup brushes to get into the tight curves & welded corners. Together both tools did a great job getting down to bare steel, so we could come back in paint with a metal primer & a top coat to restore the steel bridge to very good condition. I wore a Tyvek coverall w/ hood, booties, safety goggles, 3M P95 respirator and gloves because these tools really throw out some fine grindings that you don't want to breathe or get in your hair, skin or clothes, for that matter. We also used a large tarp to catch the grindings rather than let them get into the environment. Take care of yourself, take care of your fellow workers and take care of the environment. And use the right tools to get the job done efficiently.
I am 74 and purchased just yesterday, my first 115mm (4.5 inch) battery operated grinder however, I have yet to purchase any grinding or cutting discs while I research exactly what it is I need. Thank you for providing a large part of that information & knowledge ... I am that much nearer to selecting and purchasing my first disc or discs, with which to 'giving it a go!' Thank you again for sharing your knowledge and experience.
I can certainly agree about wearing safety equipment for your face with these, or even Dremel type tools. Just a couple of weeks ago, I was wearing safety glasses and a face shield, and still got something in my right eye. I was moving around a large part I welded together, and didn’t realize that the massive sparking was traveling around the wheel as I was moving. It ended moving around right at my face. That’s a huge amount of sparks. One managed to get through, and in my eye. Fortunately, it wasn’t too hot when it got there likely bouncing around inside my gear before entering my eye. But, if I didn’t have that protective gear, I could have had a massive problem. I’ve been doing this for a long time, and I’m normally pretty careful (don’t listen to these guys on TH-cam who tell you to take the guards off the grinders). But the more you do, the greater chance something will go wrong. Don’t be stupid, it’s not manly to go blind.
Don’t ever take that guard off I’m a welder but I did roofing work with my father and some idiot from the other company said this how a real man uses a grinder took the guard off cut some metal the disc broke and cracked hit the dude in his shoulder and by his neck
Just purchased my first personal grinder and full face shield. The grinder at my work always made me super nervous to use, no guard and no handle. Great tips! Feeling so much better now
I rarely comment on TH-cam but could not pass this without saying what a fabulous and concise video this is. Thank you so much for this. I learned an awful lot. The only thing I would add is some safety glasses. I am sure this video will undoubtedly prevent many accidents
Great video Tim.Also a good safety tip is: Keep your head and body out of the plane of rotation of the disc, because in the event of kickback or wheel failure, you're not in the most likely path of shrapnel. Also, gloves can be an entrapment hazard between the guard and the disc. Very impressed you said clamp the work and put both hands on the grinder - I see a lot of TH-camrs not doing this - very dangerous practice to hold the work with one hand and operate the grinder with the other.
Agreed, except I would recommend wearing gloves definitely with wire wheels and brushes. If your glove gets caught in-between the disk and the guard, it's in the wrong place to begin with. Just make sure your gloves fit... well like a glove. No flappy bits and strong fabric made for the purpose. They will keep your hands from being stripped to the bone.
Great post Tim. I tend to have 3 grinders on the go at any one time. 1 with a cutting disk, 1 with a grinding disk and one with a wire cleaning wheel. I used to use my grinders without a guard but after seeing many horror stories when things go wrong, I always use the guard and eye protection.
*Grinder 1: Cutoff wheel* *Grinder 2: Grinding wheel/flap disk* *Grind 3: Poly rust/strip disk - great for stripping alum etc of paint without cutting it in half*
Thank you! Found your video by accident. But great to see you focus on Safety! The information you provide is great for new/future metal enthusiasts. For 15yrs, I have offered welding and metal working to mostly novice students. And Safety is a constantly being taught. At the end of the day, most students appreciate the safety aspect of my class. Again, thank you for your safety information.
Thank you very much , I ordered an angle grinder today and while I waiting it to be delivered, I thought it was wise to learn some tips since I have never used one before. Thank you once again for this video which was very helpful.
I got my first angle grinder two days ago. Today, i went out and got a 5 pack of metal cutting discs, a stone cutting disc, a hard metal grinding disc and a 40 grit flap disc. Ive got everything i need to grind away 😊
Tim, I gotta tell ya....I love your videos. I know all about grinders and wheels, but you do an awesome job of explaining things in such a simple way that I watch all your vids anyways. thanks man.
Superb detailed instruction, Thank you. When you're new to purchasing something, it's always a benefit when you have video's like yours that help what to look out for before buying.
Tim I'm very happy that you explained the disc and which side of the Tom ring should be turned into the disc I was always confused with this and I only use my angle grinder as a home hobby on a rare occasion so I usually forget by the time I use it again.
I have a project and realized I need to buy and operate a grinder. So I looked you up and I think I'm well prepared! Thank you so much for an enjoyable lesson on what to buy, how to handle it and especially the safety gear to use. I have ordered safety goggles and a flip-up face shield along with my grinder. I've subscribed to your channel. Thanks again.
This vid was exactly what I was needing for my cutting wheel/angle grinder, answer. (I have the same model Dewalt you have in the vid so it was perfect for me). Have referenced this channel for countless tips/procedures for all my welding. Thanks again for posting. 🇨🇦👍🏼
Thank you so much for your videos! I recently learned to weld Stick and have been working with metal and grinders/cutoff wheels a lot at my new job. It’s all so new and unfamiliar to me and I mostly learn by observing and asking questions, but it’s great to watch your videos so I approach things with a bit of basic knowledge in my back pocket!
That was excellent. Learned heaps. Very little experience with an angle grinder, but I do own one. Think I am alot more informed in its use and safety.
Thank you so much! This was extremely informative. Now I feel like I can go into the store and make an informed choice for doing larger wood carving projects!
I remember a situation at the construction site where several older workers gathered around to talk about something and one of them was setting up the angle grinder. The moment he turned it on, the disk exploded into million pieces. Luckily, everyone walked away without a scratch. Few minutes before that, a huge drillbit had snapped while being operated by another guy. Do these things happen on a regular basis? This was 3 years ago, and I was a fresh structural engineer. So after this and quite a few other accidents at that very site, I decided to pursue the rest of my career in the bureau. Thank you for making this video and make me feel a bit more comfortable with power tools.
Hello Tim. I did learn from this video plus laugh a lot remembering mishaps that I have had in my shop. like paper towels catching fire because the sparks. and other things. I love your video and enjoy the very much. too bad you are on the other side of the world for me. really need friends in this type of job to share experience. you know. I learn to weld by doing it T.my church. during the 90's and started watching welding videos about weldingike 3 or 4 years ago. Greeting and Lot of blessing from Honduras
Just discovered your excellent channel. A great introduction to angle grinding but there is one thing I don't think you mentioned. Most grinding and cutting discs have an expiry date beyond which they are not safe to use due to the adhesive that holds the grit getting weaker. It is usually printed on the inside ring of the disc. Not an issue if you get through discs regularly but DIYers may keep discs for years due to occasional partial usage.
Great post, but you missed a type of wheel that I find super useful. The scrubby pad kind, called a strip disk. It's great for cleaning material before welding and painting. It takes off mill scale and rust really well but doesn't take off much metal like a flap disk can.
When using a wire wheel on an angle grinder would you recommend one with a variable speed or not? Some say that is best but they tend to be quite expensive.
This is a terrific video, packed with good information, well edited, and entertaining to watch. We're smart, and you acknowledge that by not repeating yourself. Thank you!
Hey man, if I remember well cutting discs have an expiration date. What about flap discs, do they expire? How long do they last if they are sitting in the cabinet outdoors?
The second one is Halotron. I do some electronics work and this is a specialty extinguisher that won’t cause additional damage to electrical equipment.
heyy. thank you very much for the tips o disc and for the safety somtimes we want to run forgeting the first rule. safety very usefull video. congratulations !!!
Thanks for this excellent video. I'm new to grinding and found it very helpful. You mentioned a variable speed grinder, but it doesn't seem like it's your tool of choice. Are there any jobs that you use a variable speed machine? Perhaps that's more suitable for working with wood as some have mentioned.
Thank you for your safety tips , according to my experience, I would like to share my experience. Angle grinder is very useful at the same time can be dangerous. It is an unpredictable powerful machine , specially more power and speed causing it more unpredictable. For those who have an accident , use the used, one with lower RPM , use those with less watts , hold it tight, grip it right and stand comfortable expect that although you are doing all right, but something goes wrong.this machine kicks back and you have to control it tight .be alert at all the times , if you are tired do not work with this machine..
Hi Tim, thank you for the valuable information. I started using an angle grinder for embellishing some wood turned objects. How to safely use the angle grinder was explained very well in the literature that came with it. However, it was very difficult to try to understand the different discs And how to properly buy and use them as this information was not included. Great explanations and videos. Tina
Only one tool frightens me more then my 9 1/4 circular saw and that’s my angle grinder in cutting mode! Thanks for your valuable information! I feel a lot more confident now.
Great fucking detail...love all the small details for us that are clueless when it comes to any type of tools..I learned a ton..please keep the videos coming!!! 👏👏👏
Question, how tight should that nut be after putting the wheel on the grinder? Cuz i've heard of a view accidents where came off while spinning and the those welders sustained some nasty injuries.
Great information. I want to clean my bathroom floor tiles which are made of Ceramic. They are sturdy and 25 years old, but stained and calcified because of the extremely high TDS water. Can you please advise the right tool? I stumbled upon Angle Grinder which can do the job with wire brush and steel cup. But also saw the Orbital Sander, I don't know if that will work, as they use it for polishing, but unable to see any reference to removing calcification and stains. Please advise.
I’ve used an 90 degree air grinder at work for 20 years 2” composite for aluminum and occasionally steel to relieve clearance issues. Never had one blow apart but I’m careful, I use deerskin snug fitting gloves to protect my hands as being careless 1 sec at 20K rpm will cut through that glove and nick you pretty good. I have prescription safety glasses with required side shields but if the work will support it I’ll wear a face shield to add another layer of protection. No shield on the grinder. At home I use the shields on my welding grinders as much as possible. I started with an older slower battery powered ryobi at 8K rpm and that one I use with a wire wheel. I’ve actually purchased a few with power cords as they are lighter. I’ve found the battery powered models wear you out with the weight over time.
Hi! I'm a photographer and am doing a calendar shoot with firefighters. Years ago, I had worked with a metal sculptor and done a series of model images with sparks he generated. This time, trying to do it without him and was planning on doing an Angle grinder with cold rolled steel. I'm assuming a larger diameter disc and higher power motor will work best. Are there any specifics you would recommend? The sparks will be bouncing off the models body btw.
@2:47 It can be a big hassle to get those threaded wheels off the grinder after you finish because they are sooo tight. To avoid that I use a rubber 3/4" garden hose washer that I slip onto the grinder first and then tighten the wheel down. The washer will compress as you use the wheel so it leaves about 1/16" separation so the threaded wire wheel comes off as easy as if you were using a non-threaded wheel.
So some grinders have a third handle mount on top. Seems like it would be handy for vertical surfaces or vertical cuts. That feature seems uncommon on grinders though. Wonder why?
13:05 I am a first time angle grinder user. Great video for a newbie. What kind of wheel do you suggest to remove residual glue left from an outdoor carpet on concrete steps
Yes, if you search for 'strip disc' on amazon, those wheels work pretty well. Wire wheels aren't too bad either. I'd also wear a respirator or at least a dust mask to avoid breathing in the dust from paint removal.
My own experience with angle grinders has led me to the conclusion that YOU MUST USE GLOVES, at least with wire disks. If you have never been “bitten” by a wire wheel turning 12,000 rpm, it is hard to believe what damage they can do in the blink of an eye.
@@allanmears4218 I guess you pick your poison, but, unlike a lathe, drill press, router table, table saw etc. with handheld tools you have to worry about them jumping out of position and presenting a hazard from an unexpected direction. I have never been “grabbed” by, say, my Milwaukee Magnum wrist-snapper corded drill, though it is 8 amps and wants to rip all the tendons in my hands to shreds with torque.
On a bench grinder yea you wouldn't want to use gloves because they can suck you in but with battery powered hand tools you most definitely want to use gloves and always wear eye pro @allanmears4218
something you missed about the cutting and grinding discs, a lot of them have an expiration date stamped on the inner ring, google says it's 3 years from date of manufacture. seems to be more like a best before date though, i've been working through a 50 pack of "expired" in 2018's and no notable stories to share. i like how you only showed knotted/twisted wire wheels, i hate the wire brush ones. i find the knotted ones aren't as grabby if you catch an edge the wrong way and i've never had one of the knotted ones stick a bristle into my ball bag.
Great tips on how to hold for a cut! I have gotten a hot bit from a wire wheel, running on the wimpy cheap HF grinder, to somehow go around the face shield to hit my eyelid. So I'm gonna actually follow the guidelines I've seen that you still need to wear goggles under a face shield. I will agree that the trigger switch grinder is much nicer than the slide switch...
Yes my friend," I also see you as a good teacher. I was a teacher myself but never a stick welding teacher. i have seen many videos but yours i liked most because the way you explain has a lot of sense (logic)
On my welding mask I got Shade for welding Grind for grinding but what is cut mode for is it for plasma cutting or Acetylene cutting torches I think it goes to Shade 5 setting
Hello, don't be tired I had a question Is it possible to cut a iron square box profile that is tangent to the wall with an angle grinder? Considering that the iron sqare box profile has no distance from the wall, the cutting wheel may hit the wall, will the cutting wheel's collision with the wall cause the cutting wheel to break, or will there be no problem?
Is there a specific reason that many fabricators tend to work with the flap discs instead of the hard grinding wheels? I cant understand why they would choose a more expensive disc that wears out faster and has a bunch if flex to it over a hard disc when they are grinding their welds smooth

- Thanx a multimillion for sharing clear, relevant info on using my angle grinder.
Your comment was 3 months ago. What did you do? Did it work?
Excellent video thank you. Answered all my beginners questions.
Buying my first angle grinder today. Thank you.
Great post, but you missed a type of wheel that I find super useful. The scrubby pad kind, called a strip disk. It's great for cleaning material before welding and painting. It takes off mill scale and rust really well but doesn't take off much metal like a flap disk can.
When using a wire wheel on an angle grinder would you recommend one with a variable speed or not? Some say that is best but they tend to be quite expensive.
Great video! Thank you for the instruction and the safety pointers.
Hello Tim can you tell me which disc is best suited to sand off zinc coating before welding
Excellent video Tim. I always snap my used discs in half so people (my grandfather) don't take them out of the garbage and try to use them!
Great idea. I'm the type to take stuff out of the trash and use it 😂
Other than the reasons you mentioned in the video, how can you tell it’s time to change cutting wheels? Do they wear?
Thank you for shating all the grinding, cutting, and safety info
What would you use to cut tin?
This is a terrific video, packed with good information, well edited, and entertaining to watch. We're smart, and you acknowledge that by not repeating yourself. Thank you!
Hey man, if I remember well cutting discs have an expiration date. What about flap discs, do they expire? How long do they last if they are sitting in the cabinet outdoors?
Excellent video. 👍
Additionally, I like the idea of a second fire extinguisher in case the first one catches fire.
The second one is Halotron. I do some electronics work and this is a specialty extinguisher that won’t cause additional damage to electrical equipment.
heyy. thank you very much for the tips o disc and for the safety
somtimes we want to run forgeting the first rule. safety
very usefull video. congratulations !!!
Nice explanations on small tips I didn’t realize. If I were using a grinder all day long I’d definitely use a respirator, not a drywall dust mask.
Thanks - so I only need to do up that threaded washer very loosely with my fingers - so why did they include a spanner?
Thanks for this excellent video. I'm new to grinding and found it very helpful. You mentioned a variable speed grinder, but it doesn't seem like it's your tool of choice. Are there any jobs that you use a variable speed machine? Perhaps that's more suitable for working with wood as some have mentioned.
Thank you for your safety tips , according to my experience, I would like to share my experience.
Angle grinder is very useful at the same time can be dangerous. It is an unpredictable powerful machine , specially more power and speed causing it more unpredictable. For those who have an accident , use the used, one with lower RPM , use those with less watts , hold it tight, grip it right and stand comfortable expect that although you are doing all right, but something goes wrong.this machine kicks back and you have to control it tight .be alert at all the times , if you are tired do not work with this machine..
Hi Tim, thank you for the valuable information. I started using an angle grinder for embellishing some wood turned objects. How to safely use the angle grinder was explained very well in the literature that came with it. However, it was very difficult to try to understand the different discs And how to properly buy and use them as this information was not included. Great explanations and videos. Tina
Thanks for the detailed information. How about wheels or disks that are designed for cutting wood, what is the right direction for installation?
I've never used one to cut wood...
Thanks
Answered my question at 3:14 flipping the nut over.
Only one tool frightens me more then my 9 1/4 circular saw and that’s my angle grinder in cutting mode!
Thanks for your valuable information! I feel a lot more confident now.
Really helpful, clear explanations too, big fan
Great fucking detail...love all the small details for us that are clueless when it comes to any type of tools..I learned a ton..please keep the videos coming!!! 👏👏👏
Yours is my favorite of all the welding channels I've seen (and I've seen many). Thanks for this great angle grinder primer! It's exactly what I need!
Question, how tight should that nut be after putting the wheel on the grinder? Cuz i've heard of a view accidents where came off while spinning and the those welders sustained some nasty injuries.
Great information. I want to clean my bathroom floor tiles which are made of Ceramic. They are sturdy and 25 years old, but stained and calcified because of the extremely high TDS water. Can you please advise the right tool? I stumbled upon Angle Grinder which can do the job with wire brush and steel cup. But also saw the Orbital Sander, I don't know if that will work, as they use it for polishing, but unable to see any reference to removing calcification and stains. Please advise.
I’ve used an 90 degree air grinder at work for 20 years 2” composite for aluminum and occasionally steel to relieve clearance issues.
Never had one blow apart but I’m careful, I use deerskin snug fitting gloves to protect my hands as being careless 1 sec at 20K rpm will cut through that glove and nick you pretty good.
I have prescription safety glasses with required side shields but if the work will support it I’ll wear a face shield to add another layer of protection. No shield on the grinder. At home I use the shields on my welding grinders as much as possible. I started with an older slower battery powered ryobi at 8K rpm and that one I use with a wire wheel. I’ve actually purchased a few with power cords as they are lighter. I’ve found the battery powered models wear you out with the weight over time.
Hi! I'm a photographer and am doing a calendar shoot with firefighters. Years ago, I had worked with a metal sculptor and done a series of model images with sparks he generated. This time, trying to do it without him and was planning on doing an Angle grinder with cold rolled steel. I'm assuming a larger diameter disc and higher power motor will work best. Are there any specifics you would recommend? The sparks will be bouncing off the models body btw.
@2:47 It can be a big hassle to get those threaded wheels off the grinder after you finish because they are sooo tight. To avoid that I use a rubber 3/4" garden hose washer that I slip onto the grinder first and then tighten the wheel down. The washer will compress as you use the wheel so it leaves about 1/16" separation so the threaded wire wheel comes off as easy as if you were using a non-threaded wheel.
I am a total non-DIYer but I need to convert a threaded rod into a smooth rod. What blade do I use to remove the threads.
Can you make a video about assembling the "cutting" wheel...and everything has has to do with the cutting blade, thanks.
So some grinders have a third handle mount on top. Seems like it would be handy for vertical surfaces or vertical cuts. That feature seems uncommon on grinders though. Wonder why?
Can I use this tool to refinish a terrazzo floor? Thanks...really enjoyed your video...
13:05 I am a first time angle grinder user. Great video for a newbie. What kind of wheel do you suggest to remove residual glue left from an outdoor carpet
on concrete steps
I have had a few grinder wheels explode and you never find all the pieces. Thank you for the great video and for highlighting unplug, guard etc.
Thank you very much, excelent video. Quick question, it is ok to use a grinder to remove paint from a Metal surface ?
Yes, if you search for 'strip disc' on amazon, those wheels work pretty well. Wire wheels aren't too bad either. I'd also wear a respirator or at least a dust mask to avoid breathing in the dust from paint removal.
Great, thank you Tim!
My own experience with angle grinders has led me to the conclusion that YOU MUST USE GLOVES, at least with wire disks. If you have never been “bitten” by a wire wheel turning 12,000 rpm, it is hard to believe what damage they can do in the blink of an eye.
I will never use gloves with any rotating machinery. Too much chance of it grabbing you.
@@allanmears4218 I guess you pick your poison, but, unlike a lathe, drill press, router table, table saw etc. with handheld tools you have to worry about them jumping out of position and presenting a hazard from an unexpected direction. I have never been “grabbed” by, say, my Milwaukee Magnum wrist-snapper corded drill, though it is 8 amps and wants to rip all the tendons in my hands to shreds with torque.
Afaik wire wheels are rated at lower rpm than 12000. Last one I bought is rated at 8000rpm
I got hurt and cut a mast chunk out of my finger with an angle grinder. I took the the guard off too. Was a bad idea.
On a bench grinder yea you wouldn't want to use gloves because they can suck you in but with battery powered hand tools you most definitely want to use gloves and always wear eye pro @allanmears4218
something you missed about the cutting and grinding discs, a lot of them have an expiration date stamped on the inner ring, google says it's 3 years from date of manufacture. seems to be more like a best before date though, i've been working through a 50 pack of "expired" in 2018's and no notable stories to share.
i like how you only showed knotted/twisted wire wheels, i hate the wire brush ones. i find the knotted ones aren't as grabby if you catch an edge the wrong way and i've never had one of the knotted ones stick a bristle into my ball bag.
Great tips on how to hold for a cut!
I have gotten a hot bit from a wire wheel, running on the wimpy cheap HF grinder, to somehow go around the face shield to hit my eyelid. So I'm gonna actually follow the guidelines I've seen that you still need to wear goggles under a face shield.
I will agree that the trigger switch grinder is much nicer than the slide switch...
Really appreciate your video, as an novice.
Dude!!! Awesome video. Been a handyman for a little over a year and just now having to educate myself about grinders
Quick question do grinding and cutting discs have a shelf life thank you for sharing your wonderful videos I am watching from South Africa
Yes they do have a shelf life. The expiry date should be written on the abrasive wheel.
Yes my friend," I also see you as a good teacher. I was a teacher myself but never a stick welding teacher. i have seen many videos but yours i liked most because the way you explain has a lot of sense (logic)
Thank you very informative!! Im a girl. Dad never taught us about tools. I love remodeling, repurposing.
If new to grinders this video will answer a lot of your questions
On my welding mask I got Shade for welding Grind for grinding but what is cut mode for is it for plasma cutting or Acetylene cutting torches I think it goes to Shade 5 setting
That’s right. Lower amperage plasma cutting and oxy-fuel.
Do you know what grinding attachment to use to remove polyurethane sealant from concrete expansion joints?
Hello, don't be tired
I had a question
Is it possible to cut a iron square box profile that is tangent to the wall with an angle grinder?
Considering that the iron sqare box profile has no distance from the wall, the cutting wheel may hit the wall, will the cutting wheel's collision with the wall cause the cutting wheel to break, or will there be no problem?
Is there a specific reason that many fabricators tend to work with the flap discs instead of the hard grinding wheels? I cant understand why they would choose a more expensive disc that wears out faster and has a bunch if flex to it over a hard disc when they are grinding their welds smooth
They remove material faster and are less likely to leave grooves. Both types have their place, though.
