Watch as we unbox and mount the Harbour Freight Chicago Electric Rotary Saw Blade. This is an extremely dangerous rotary tool accessory so use at your own risk.
Always clamp down or hold in a vise your workpiece.
Yes helps keep all hands farther away from the blade. Same goes for cutting metal with metal cutting tools. Never know when the cutting tool will snag and get caught in work piece.
Eh, I just use my fingers as a guard piece! Still have a whopping 3 guard pieces left!
As shown at the 8:00 mark
Tay Reptar And how many fingers do you have left?
Absolutely clamp and vice only. No hands unless you don't like your hands and fingers then have at it.
never use a cutting tool on a dremel while holding what you are cutting with your hand. This demonstrates how not to use cutting blades.
All he needs are some loose fitting gloves
I just bought this set of blades and a Chicago Electric Rotary Tool Kit (#63389) from Harbor Freight that has a 9 volt rechargeable battery pack. You keep mentioning that this is a very dangerous tool and not meant for kids. Well, ALL power tools are not meant for kids! I also agree with the other comments that your object to be cut should be secured with a bench or table vise when being cut. Lastly, if you are careful as an adult, you don’t need to unplug the power when attaching a saw head as mine is battery powered. I just make sure that the power is off.
I find it very rewarding to use my rotary tools with the Cub Scouts to work on their pinewood derby cars. The kids love the tools and love to see the finished project.
Thanks for watching.
All of the cutoff wheels are dangerous, but they’re extremely useful when used carefully
all tools are dangerous if used incorrectly
Some are more dangerous than others.
Thanks for infos. You are the real a danger searcher by cutting free hand ;-)
I've used these for many small projects and never had a single issue. Now that being said first off don't hold the object your cutting in your hands use a vise. Second eye protection is a must and even consider some good trustworthy gloves. And as stated in video never attach any dremel bits while plugged in that's just my opinion too. If you're not familiar with rotary tools I wouldn't advise using something like these. But I must state this again never ever hold the object you're cutting with these in your hands that's a big problem you're asking for doing that. Also never force tue tool to cut more then it's supposed too and always use commonly sense that goes for many tools honestly common sense. I watch many restoration channels and it's scary even just seeing how so many people use angle grinders without guard attached especially when you can find many videos on how easily they fail and can cause seriously bad harm. Run a saw blade such as these should be used only for small projects with all the proper steps taking as they can be very dangerous aswell.
Any tool is dangerous if used improperly. First, really who unplugs their tool every time they change a bit? I have this kit and have used it extensively with no problems. Your project should be clamped down NOT held in your hand. Or mount your tool and move the project. Also the harder the material you are cutting the faster your blade should be running. And go slow, if you force it or try to cut too fast it will grab causing it to jerk. What is dangerous is the improper use of the tool NOT the tool
@bojo perez same, you can accidentally turn it on. it has hppened before to me, fortunately i didnt get hurt
What's the difference between the damsel and the Chicago?
For a video on safety it was a dangerous example to both hold the small piece of timber and then actually perform cutting towards your face area, a big no no . I would advise both hands on that tool for guidance alone, though a small safety guard wouldn't be that difficult to fit either. Tools are only dangerous if you have no respect for them, keep eyes open at all times and never strain the blade beyond it's capability.
Thanks for that video and the instructions on how to install that circular head.
must install blade so its cutting in the direction your rotary tool spins as rotary tools are NOT reversable
Rotary tools, like my Foredom and RAM are reversible. This one only reverses by flipping the blade over.
Reversing the blade or the direction is turns allows you to come at material from different sides, to always keeping the debris from cuts and grinds throwing away from you, AND so the blade or bit wants to run away from you, rather than at you.
Such a strange take on this tool…you dislike it because it’s unsafe, but it works fine. I’m just not sure I follow that rationale, but I was looking for a video of these in action and this was that so I’m not disappointed.
Have this harbor freight Chicago rotary tool, and its a great bang for the buck!
The title led me to believe there's some flaw in the product and it should be recalled...
I've used them for many minor projects with no issue's. I guess honestly it depends on what you're cutting as far as hardness and thickness goes. I only used them for thin stuff and balsa wood as I make my own fishing lures as a hobby. It works great for cutting off small sections but I would never use it to cut long runs or thick wood.
What should be recalled is the person using it. 🙄
I went out with my dog impatient for his walk and never manages to cut the gelled 6onz fibreglass cloth covering my future fin boxes on my surfboard glass job. My last resort is this tool. never having used one until I milled out the slots to put in the fin boxes I now have to be careful and try cutting the slots open for the fins. easy enough I guess until I realized the sawblades I bought on ebay, from China, never came with that manderil bit. so that's why I came on here hoping to learn something. one things for sure anti clockwise means its heading straight for me at face and stomach level so I'm wearing extra protection thankyou for the video SURFS UP. I keep hearing about Harbour Freight, wish we had that store in the UK
How do you still have all your fingers working like this.
Wish you could post a picture. Blade is mounted to mandrill. Mandrill is bent 90° about halfway down. It's my favorite paperweight set in 4 inch of clear epoxy resin, complete with the drop of blood.
Maybe a video of all the 'near miss' pics. Thanks for watching.
I find using the dremel without the flex shaft more sturdy
I love dangerous stuff. Specialty when shaping on the fly, no clamps, hold down of any type. You should build your self a table saw top and holder for your tool. and use it as you would a grinder or table saw.
I’ll be wearing a suit of armour using these 😮
Hay thanks for showing the sawling blades.
Great video and instructions! Thank you.
I kept waiting for it to hop up and cut your left hand. My butt is sore from clenching the cheeks. Dman it!
Thank you so much.Truely appreciate it.
Thank you for reminding me of this. I know precautions for circular saws 7 1/2 inch but I honestly didn't think of the same precautions against kickback and binding for a saw this small. It seems harmless enough but it could make short work of hands which will always be in the vicinity because there is no table locking, and clamping is sometimes an afterthought. Same value in eye protection precautions. Close work and need for unobstructed visual focus can put users at risk for eye injuries even more than major power tools.
I make my own blades just like these. They are dangerous so I always clamp what I'm working on , cover my neck with a bandana, and wear safety glasses. It's not a good idea to hold your work piece in your hand while using one of these blades. They will cut your fingers to the bone very easily. I've never had a blade break apart but I cover my neck just in case. These things are scary. Every time I use one I picture it breaking apart and sending metal shards into my neck. I use mine fore cutting bone when I make stuff from bone. It works so well it's easy to picture what it could do to your fingers. Also do not use one of these blades if you aren't experienced with dremels.
Yes a camping is really necessary otherwise injury must 🤒
what material did you make them out of?
I was thinking to make guard with some bottles plastic top, then I had to buy the EZ Dremel accessories, more easy and safe .also you can buy the protection cover case in Amazon, for 10.00 txs love your videos
These blades are made to fit tool 670, not used like this. Also there is no choice which way you attach the blade. The plain side goes opposite the chuck. The teeth are angled for one direction of cut. Wood to be cut needs to be held in a vice.
Thank you. Helped me a lot.
My saw attachment screw is loosening while cutting. How to correct it.
Let's just forget the fact that Dremel says to never use that adjustable chuck with the flex attachment lol
Mine have holes so far off they are unusable; 2 are so bad you can easily stand back 5 feet and see the off-center. Does anyone know how to make a fixture for those little saws?
Thanks. I'm teaching my 17 yo grandson to use a dremmel. I'll have him watch your videos.
Sandra Wade ....don’t do that, teach him use and respect for sharp implements yourself Grandpa. That’s why they invented grandpas.
May I suggest a foot pedal for safty
Debated getting one of these saw blade kits cause I bought a cheaper wireless rotary recently cause I just wanted something portable to cut small wood chunks off with before actually carving with my dremel lite. Honestly suprised there aren't universal shield guards for more rotary tools out there besides dremel. Are there any drilling/cutting bits that can do more curving/circular cuts in wood or am I just using the wrong tool
👌👍Subscribed, pressed bell🔔.. Thanks🙏 from..India🇮🇳
Do you have a video comparing the Warrior rotary bits to the dremel ones? If not, are the dremel tools bits higher quality? By a lot or a little? Thanks.
Great video, So its not recommended to attempt to cut curves seeing that would call for turning or twisting the blade a bit ? Thank you.
If you want to cut curves, you should consider getting a routing accessory and a routing bit. They look similar to drill bits. You can also use a cutting bit, which also looks like a drill bit, but is designed to cut from the edge, while the routing bit is designed to cut at the bottom. If the material is thin enough, then you _can_ cut curves, but you must do it top-down. So you're only ever cutting straight down. I just did that on a thin piece of metal, with a different disk, of course.
When that pine came out of your hand I said NOPE
I tried using this same set last night, just purchased it so it had never been used, at least not by me. I've never used this type of accessory on my dremel before, but I use large saws and other power tools often, and I use my dremel often. But anyway, as soon as I turned my dremel on and it started spinning the damn mandrel bent!!! Thankfully I turned it off before it bent more and the blade started hitting the dremel or broke off! I'm not sure why it did that, if it was something I did wrong or if the mandrel was damaged before I attached it. Does anyone have any experience with that issue or have any insight to what might have happened so it doesn't happen again?
Good information. Thank you!
Forbidden electric toothbrush
I bought one similar to this and the mandrel bent over at 45 degrees. Only had my tool set at number two. Probably at 8000 rpm.
Good video
You can get injured from using any tool that will remove material in any manner from any material as hard, or harder, than human flesh. That being said, what in the everloving prompted you to talk safety then have your flesh in close proximity to the cut on the workpiece? I know a professional that lost four fingers because he got careless and tried to bump move a piece of wood with a running saw. That little saw may be little, but it is no more OR LESS dangerous than a table or radial arm saw. If any power saw binds, it will buck, and if you have flesh in the way, you will lose some. Please don't do that again, okay? (Familiarity breeds contempt and power tools just don't care, even little ones like dremels.)
Ive had the biggest blade in a flex shaft, working on a project, somehow grabbing in the inner pant leg of my shorts... I was lucky and dumb that day, no damage, also had the blade fly off from lack of tightness on the screw
Thank You!
If you're not sure you can cut straight consider drawing a line on your material and securing cutting piece with clamps.
Good Info!! Thank you!
For these type of cuts I use my dewalt oscillating tool. It is designed for these type of cuts
Being a safety professional for 30 plus years, I have seen some serious accidents with rotary tools being large or small and I agree with Karl this is a serious tool. I would recommend to use a face shield with safety glasses. Good Class.
Yes Sir. This is a preventive measure. Why not design a safer Mandrel with a shield and a speed controller on the drill body itself? Many jobs do not need 20,000 rpm speeds. Also as the saw blades are made of thin sheets the drill should be clamped and job moved across with a guide so that it goes straight and does not twist.
You been a safety professional for 30 years ? That is hard to believe since you didnt moment the fact he was holding tiny pieces of wood in his hand trying to cut each one. That was very dangerous and no common sense
I have a scar in my forehead from one of those blades, still have the blade and the broken mandrel
Protect for hands and face, use correctly, and no problems.
What's minimum blade size in Drexel to cut slate I need to cut 6mm depth in wave shape
I wouldn't recommend using this accessory for cutting any material.
Will these work for the hyper touch rotary tool
If you use the correct collet, yes.
This tool is incredibly dangerous, I almost took my finger off a few minutes into use and needed lots of stitches. It can be used fairly safely but dremels do get stuck and kick sometimes when cutting highly irregular parts.
Say. Although you used the saw blades on wood, can they be used on plastic ? Or is another type of blade is used ?
Is this just about Harbor Freight saw blades or all rotary tool blades?
Because of this beautiful tool, I now write to you with just one finger, the one I barely see with the eye that remains.
Ouch!!!!!!!!!!!!
Should hv provide Transperant Polycarbonate Coller for Disc
What did you have it plugged into ? You never showed what was powering the blade.
LadyInKY .....what are you, a dumbass? It’s hooked to his washing machine, everybody knows this man. Get with the damn program!
As soon it flew out of his hand im done...☠️👀
I can't get mine to stay done up every time I go to use it comes undone . Ha vent got a vice or similar to do it up with just a screwdriver... ? Help
Loctite or some other thread sealer may help. Stay out of the cutting line of the blade.
That particular set of saw blades is pretty cool, but definitely not the safest route for cutting. One thing I didn't like about it was that the hole in the blade has to much play which ib turn crwates wobble and eats up collet's. There's probably a fix for this, I would assume something to fill the slop in the blade mounting hole, even some paper, cardboard, or tape..? Think I'll give that a shot right now as a matter of fact.. excellent video and good safety advise..
The mandrel dia. should be the same size as the hole in the saw and back collar to push the saw against the collar and tighten with a nut with the washer on the mandrel having outer threads. Not with a screw on an inner hole. This will stop the WOBBLE. also aguard made from a jar Lid,
I saw those on the shelf recently. They look scary. I kept moving...
Far more dangerous then a radial arm saw. But slightly less dangerous then the thin disc cutoff wheels that shatter with the slightest off axis twist.
THX SOLD!!
really intended to be used with a trigger style rotary tool, so it doesn't keep going should you lose control or drop it. this is the principal design used for surgery, those don't even have guards.
I think Ducky used one in NCIS.
I forgot about autopsies. I think I have seen it as well on NCIS (and shows like it). images.dotmed.com/images/listingpics/979400.jpg
ri mar I used something similar for a frog necropsy. It worked well when sharp, but was a cheap knock of that quickly dulled. Something like this might work well, but perhaps the teeth aren't fine enough.
ri mar but wouldn't the blades for autopsies be carbide tipped. I mean they do saw the skull open to examine brain.
ri mar rotary cutter for bias strips where can
I get it to buy
Sliced my thumb open with one of them awesome blades. Just one them freak accidents. Plus side didn't hurt much
Hope it wasn't too bad. Thanks for watching.
The blade flew off and hit me in the chest - the easi lock metal disc in the middle completely came off !! I am newly widowed and trying to fix things but what can I have done wrong I'm scared to use it again!!
Best advice I can give on that....if the tool scares you, don't use it. My girl is scared of the router and insists that I am 3 feet away when she turns it on.
The screw that holds the blade down cannot handle the vibration at this high speed... Even the dremel blades are not designed this large... if you have to use some type of circular saw for wood just use the proper circular saw, rotary tools like dremels really arent designed for this sort of stuff as the tool can "kick out" of your hand. Bad idea. If you want to cut small wood pieces with a dremel just use your typical cutoff disc which is NOT metal but looks more like a small angle grinder disc...and always put the piece you are working on in a vice so it doesnt fly at you like in 8:00
I'm just learning about tools it has not been easy. I was under a vehicle for the first time trying to remove a rusty bolt. Lol. Home depot or Lowes not very helpful because they don't know. So I wait for some guy to come along and ask there opinion. I'm in the process of converting a van into a camper. If you wait for someone else the job will never get done
if use carefully and be cautious while you cutting , no risk or harm , dont use carelessly
My fingers hurt, just seeing you cut that piece of wood...
Ironically, you constantly point out how dangerous it is to use that tool without having your own caution :( Good video anyway... Thanks!.
I bought some of these to play around with, but my oscillating multi-tool cuts way faster and safer.. not even a competition 💯
You really should read about a subject called up milling and down milling as it relates to circular cutting of wood or metal. Similar to using a router and which way you want to move. I can think of no practical use for this dangerous tool. Too many options out there for cutting small items.
@8:02 gave me a mini heart attack 😨 that is one dremel attachment i won't be buying
Sir, I'm from Pakistan and I have these blades I got experience with it it is really too dangerous if your hand angle isn't good so it's too hard to cut any substance without any guard it should be fix like big bench grinding blade otherwise we can got an injury, I have face myself after injury now 2022 3 years ago But yet My index finger doesn't feel anything 🙄
Anything that cuts or rips into wood or metal is always used with caution and if you do not you need to stay away if you value your life.(not joking)
Every comment is this tool is so dangerous I would never buy this but yet I just got a pack of these and watched this to find out how to use them 👀👀👀👀👀👀👀👀👀👀👀
Just imagine what could happen , if the mandrel get slightly loose due to rpm...
Shoul hv given Friction free lock washer get loosing while Cutting if allignment is drift there is chance of getting injury
definitely should have a shield on that
Please share this on your page if you wish.
Don't rely on safety accessories, rely on safe practices. No shield is going to care if you get hurt. Every shield is going to have an opening so the tool can work. So that shield is just going to be an illusion you fool yourself into thinking you're safe. Which is itself a dangerous situation.
The one from the dremel brand has a shield
@@1pcfred common sense is needed but accidents happen no matter how careful so nothing wrong with safety features for added safety
thanks
I bought one this afternoon. Yer vid was very useful. thanks for taking time to share your thoughts and experience.
Glad it was helpful!
Modify a Plastic funnel as a shield.
It is very DANGEROUS because the cutting blade jams or ‘Kicks Back’ when you are cutting the wood etc - Something is terribly WRONG !?? 😨😰🤦🏻♂️🤦🏻♂️
You can’t stress enough how dangerous it is and state you really need to know what you’re doing with it. However you hand hold the wood, at one point bit gets grabbed out of your hand and you are cutting towards yourself rather than away from you.Would you run a circular saw in the direction of your body? Sorry but I got suckered in by the click bait title. I expected you to say it was dangerous as the saw blade comes loose and could fly off due to speed and vibration. I’ve had it happened with grinding wheels on dremel which is why I use the new click lock dremel wheels for cutting and grinding
All good points to keep in mind.
Thanks for watching.
Can it cut aluminium sir?
That would depend on the thickness.
Same as the cutting wheel bit.
Not sure of the cutting wheel you are referring to.
I literally just bought this set of rotary blades today for use in my Chicago Electric rotary tool (also purchased some time ago at a Harbor Freight). I tightened it up and turned it on at the lowest speed to test it out, as this is my first experience putting a mini saw blade on the tool. In less than 3 seconds the mandrel bent into an almost L shape. The blades are rated for 20000rpm and on the lowest setting my tool should only be moving at 8000rpm. Has anyone else encountered this? I plan to return it/exchange it tomorrow, but should I invest in another of the same brand? Is this common or a one off?
I suggest getting your money back. There are way to many options of cutting and this method is totally unsafe.
Maybe you didn't put the mandrel inside far enough. Almost all of it should go in.
Oh hell no I use mine on rocks and really don’t have to worry about your digits . That always concerns me and I think it should . Seen a few fingers laying around job sites in my time and that sucks
*With so many SAFER options on the market, I would never use this.*
Ya. This tool is dangerous as hell, even for an experienced woodworker. Mine collects dust. It’s a last resort.
To Kosmic: Why is this? It doesn't look so imposing. It's the real and large circular saw which is slightly more trepidatious.
@@eddyvideostar because the risk of the blade flying loose and hitting you in your face at 30,000RPM
I have a ideal for the sheld you can take some duck work that then metal an make a see shape gard
it looks just like my $5.00 china 6 piece kit
Be careful 8:02
I purchased this kit last Spring. I SHOULD have made a video on what happened. Before I even started cutting, the mandrel BENT AT HIGH SPEED and I almost dropped the tool from vibration. This could have been a very dangerous situation. I couldnt believe that the mandrel was that soft and weak. DO NOT purchase this saw kit unless you want to lose a finger or eye, due to that easily bendable mandrel!
WOW...
Thanks for sharing.
People....read this comment and use this 'tool' at your own risk.
Dude, mine did too. Mandrel bent badly, vibrated heavily under the speed and the cutting wheel went flying off after the screw worked lose. Luckily not into my face or body as I watched it hit the floor and ricochet off the walls into a coat I had hanging up. I was stupid enough to try it again making certain it was properly tightened and I used at a lower speed. Another fresh mandrel started bending and the wobbling began. Was able to cut the Dremel off before things went too haywire. You are right, these things are extremely dangerous.
Exacly the same thing happen to me too as soon as the blade touched the piece of wood!
wvsky i had the same thang happen to me wiyh cut off disk whats ip with the the metal posts ther making this wasnt even harber fraight it was a dremal brand .
The same thing happened to me.. I did drop my tool.
I bought this kit it is made in use from strong stainless steel.not bendable.
The scary part would be if that blade were to grab the workpiece and kickback into ur hand 😰😰
Don’t know how many times these mandrels work their way loose! Mostly with buffing wheels, as I avoid using saw blades on these mandrels styles.
There are so many other tools for straight line cutting that are safer. I personally would not have it in my shop.
