True story: coworker was using a grinder with a cutoff wheel and no guard. I was about 10 feet away. The wheel exploded on him and a big chunk hit him in the neck by his throat. I got to try to slow the blood coming from his neck while waiting on the ambulance. I’ll never forget him telling me not to let him die and that he wanted to see his kids. He got lucky and lived. Use the damn guard.

[@cindycindy4536]

I had a lot of old pipes and rebar to cut up and from what I read kzbin.infoUgkxPDBfLu68o58Aw85O_J-zIFfjJARBhp-3 this would be the tool for the job. Since I had never used one, I watched a couple of youtube videos and I'm so glad I did. Some really good safety tips, which I followed, and this tool did a splendid job. One good thing to know is the weight of the tool puts just about the right amount of pressure on the metal I was cutting, so I didn't have to use a lot of pressure, which is more likely to jam the tool. It made fast work of my job.

I am so glad I watched this. I am a novice- hobby- in the garage guy who works mostly as self-taught. Yes, I've thrown the wheel protectors away. Yes, I use the wheels for applications I should have used something else. Never knew the right way to put the nuts on and crank them down too tight. This really opened my eyes (thankfully I still have them). Going to check all my grinders tomorrow and get set up correctly. I just hope I won't have any nightmares sleeping tonight. Have I been lucky. Years doing it the wrong way. Thanks so much for your instruction.

[@rapsured]

I had a cut off wheel explode on me. I had the guard and it saved me. I didn't listen to others about taking the guard off.

[@Senkino5o]

Good stuff. I've had them blow up without a guard many times and its been like being sprayed with small bits of gravel at speed, didn't embed, might have broken skin or slightly bruised. Protect your eyes. If you blew off a wheel while it was mostly intact that might be a different story and 7-9" discs can kill.

[@brianelstro7801]

Unfortunately it happens fairly commonly, especially on deep cuts. As long as you maintain a proper body/tool orientation and adhere to the guard and cutting directions, it rarely causes as much damage as shown, if any. Be vigilant!

Lol I set my battery powered cut off saw on top of a rag as it was turning off- the rag got sucked in . I'm here to learn safety. I scrap metal and I take apart Transformers for Copper. Quick story- My friend plugged in his grinder and it was ON! It rolled on the table towards him and cut him ( just like your presentation discussed.) Battery powered cut off saws don't give me the RPMs- but at least I don't burn out/ overheat the motor. Also I'm rough on the tool- forcing it in when I should just cut it slowly- a BIG THANX for your help . Quick story- I know 2 people who cut 2 fingers on a table saw- one guy with 40 years experience has no feelings in two of those fingers!!!!!

[@conniecostner9665]

I fell at the bottom of my porch stairs 2 months ago, I had an old crock pot glass bowl that had a huge crack in it, needing to be hauled off where I take my trash. Needless to say I tried to break my fall and laid my ring finger open on dominant hand. Had about 6 stitches, about 6 staples on my wrist, a shot in my backside, and one in my arm. For my negligence and stupidity. I was supposed to go see a specialist, I decided against it. Urgent care told me they didn't have an ex ray machine but I had probably cut a ligament. Well, my finger will never be the same, and I already have deputyens contracture. I never thought something so small would make such an impact on my life!

I was cutting up a bike frame and I will admit that I didn’t have it probably secured and was using my foot to hold it on the ground.

I had the guard on and without I would have been horribly injured because there is a massive gouge in the guard that without would have sent a piece of the blade into my neck.

The people who never use guards are the weekend warriors who work in their garage and actually don't have many hours under their belt with grinders. Luckily those people have never had to use grinders professionally in a large engineering workshop or on site for 55 hours a week for many years. People who have worked on site of in large engineering workshops always wear earplugs, glasses, face shields, gloves and guards. Iv'e yet to see a welder or fabricator or even a experienced labourer not use a full set of PPE. (even the experienced labourers are much more skilled with grinders than the weekend warriors are)

Same bro I’m 14 and thinking of buying a grinder and a welder for my go cart build

[@bradleypumba]

How I got started welding is my grandpa bought me the titanium 125 Flux welder for 140 on sale for Christmas (current price is $190) and I welded tons of stuff I welded some fence that needed to be fixed wheel barrels exhaust manifold and more with that about 8 months later I up upgraded to the lincon 210 mp for the gas capability and more capability because i restore trailers and i build some massive projects but I still use that harbor freight welder some times because it is so portable (im 15 now)

[@bradleypumba]

@@Johndeer325 read my other comment if u want but to start out I recommend the harbor freight 125 flux core welder its $190 especially for a go cart because its do dang portible I own a almost $2000 welder and still use that one because its so portible good luck with ur build Edit: also I would love to see the build on ur channel im subed I'm waiting for the vid lol

As an occupational safety trainer, I really appreciate you putting this video out. Great teaching and love the box that you display the exploding wheels! Gets the level of danger across very well.

[@Abe18874]

Thank you so so much. I have used a grinder in so many of these incorrect ways. I will now be safe in all the manners you have mentioned for each type of wheel. Wow, your discussion was incredible and extremely easy to follow and understand the why, the injuries at the end ground it in! Thank you and I have passed this on to my son and friends who also need to be safer. I don't think any of us can say we do it all right, maybe because we didn't know, think to ask or whatever, but this now requires us to be safe. Just started watching you vids, an have had quite a positive impression.

[@SteagallConde]

It's extremely rare for me to watch video material longer than 5 minutes and here I paid close attention to each of the thousands of seconds you explain in an extremely didactic, absolutely technical and perfectly understandable way, thank you very much for the class because I learned more than in my last 15 years of activities in my hobby of scale model railroading, CONGRATULATIONS!

I've learned so much from this video. As a mechanic for forty years I used this equipment for for fourty years and never knew some of this stuff. Thanks for bringing safety to the fore front. This video should be used in every welding or metal fabricating class. I've seen several injuries over the years and learned from every one. This is vital information.

I been working on anything with a internal combustion engine since I was 7-8yrs old,now I'm 51. My father retired after 39yrs as a heavy equipment mechanic for a road construction company,before that he was a tank mechanic in the US Army from '57 to sometime in the late 60's. My grandfather and both his brothers were auto mechanics till they died and his brothers were older than him and they worked on Model T's. My grandfather was also one of the 1st 25 GM Master Mechanics and did R&D for GM out of his own garage in the 60's. Last I heard his 327/340 powered '62 Corvair (he developed the the kit in '63 for GM) is floating around somewhere in New England.

[@brysonalden5414]

Without a doubt the most instructive video I've ever seen on grinder operation. Wish I'd watched it years ago! Thank you for posting this.

[@WildhareXXX]

This is BY FAR the absolute BEST grinder safety video ever done! I have worked with grinders off and on for over 55 years. Never had an issue, but like most everyone I violated a few safty rules myself. Thank God and pure dumb luck, never was hurt with one. It's just not worth taking chances. You never know when your luck will run out, the first, one-thousandth, or anytime in between!

[@sharit7970]

STELLAR video! DEFINITELY put on the safety glasses! Although I wear glasses for near vision, I didn't have safetys on while cutting off some bolts, and spend half a day in the ER to have a piece of metal removed from my eye. Fun fact: if you get metal in your eye, you also will need to have the inevitable rust ring removed. Just wear the safetys- learn from my mistake

[@rukus13]

This is a good video, especially for newer people getting into welding. I’ve been welding for 35 years and and have broken every safety tip you mentioned plus a whole lot more. It’s not that I just don’t care, it’s more of the places I’ve worked at. It’s more of “get it done” type places I’ve worked. The companies first rule is to make money, their second rule may be safety (if your lucky). I even had a few injuries from a cut off wheel cutting my forehead and requiring staples, to exploding disk with fragments sticking in my chest. But looking back at all my time welding for a living, I’d have to say it’s definitely not worth it. The pay is low with long hours of standing in one spot breathing the dust, looking like a coal miner at the end of the day just to go home and get up and do it all over again. Don’t get me wrong, welding is fun but only when you do it as a hobby or on the side type job. My best advice for younger people is to get a good education and find a cleaner, higher paying job. Because after 30 to 40 years of the day in, day out bs, they will wish they had.

[@jayakarc1673]

This is deep. 🙏

[@aroncanapa5796]

I've only spent 6 years in the field and all the reasons you stated plus the fact that every place I go I seem to make less then the shit bags so I'm done with the field.

[@flacidfrank8410]

How much money were you making and what type of welding were you doing? I'm going to college for welding and you've got me a bit spooked

[@rukus13]

Flacid Frank in the 80’s I was making $4.85 an hr. Today I’m at $19.00 hr. Doing standard mig welding on square tubing, and sometimes a little tig welding on smaller/thinner pieces. Right now we are building advertising billboards that stand alongside the highways and byways. But mostly we do parts racks for major automotive factories. I’m sure there’s other places that pay more but in my small town there’s not much here. I’m now in my 50’s and after my wife passed away, I know I’ll be working way after retirement if I’m able. All and all it’s a job, but all my life I felt as if I was working just to survive. Get a good education and get a job to where it feels like your living not surviving. Also think about your health, breathing weld fumes and grind dust day in and day out is not good. And the frustration of a boss always over your shoulder wanting you to go faster or work longer hours also puts a toll on your health too. I hope this helps you on your journey thru life, it’s definitely not easy to raise a family.

Glad I watched it, I wrote 12,000 rpm on the side with a sharpie so I won't buy wheels rated below the rpm.

Thanks so much for this. I've been using angle grinders safely for many years but you still taught me new stuff, especially about putting shields around the area against sparks and type 1 guards. Can't get them in the UK so I modified a spare guard - I now feel even safer. Thanks again!

Bro!...the exaggerated unsafe scenario in the beginning was hilarious and spot- on, thanks for the video 🤣👍

[@willieengelbrecht9825]

Thank you very much for this very informative video. I am very cautious in using a grinder and lately only using smaller grinders. You gave me a lot of safety tips up the sleeve. Had almost a life-threatening incident with my big grinder almost 40 years ago, replacing floor covering with tiles, which was glued to the floor. Trying to remove the glue for better grip, the glue built up on the disk and eventually exploded - it missed me with millimeters luckily - leaving a huge hole in one kitchen cupboard.. Emphasizes using the right disk for the right purpose. Now we have special diamond disks to do this luckily.

[@skyhawaii5446]

You are a great teacher. I fear grinders for 2 reasons. First, I know someone who had a grinder accident. Second, power tools that cut freak me out because I am left handed. You covered everything people do wrong at home and or on a job site. The end of your video was and eye opener for me. I am a professional painter and from time to time, I have to use a grinder to prep metal objects for painting and a sanding disk to shave down wood, bondo or epoxy wood fillers. Some grinders have have holes on both sides. Some of my festool sanders do as well. I am not to proud to tell you and your readers, that I am now confused as to how I should hold a grinder and what side the handle should be on. I am certain there are other people out there like me who have to adapt to our handedness if a tool is designed specifically for right handed users. I don't want to be one of the guys in the photos, so I will gladly welcome any advice. In additional I saw a guy on a job site take a worn out sanding disk and peel off all the paper and use the remainder as a cutting disk for metal and tile. Will this work, or is it another way to potentially be in your photo contest if things go wrong? Again, many thanks for taking the time to make this video. Respects, Sky

[@kaw420TSVR]

I’ve been using grinders on everything over the years but only having seen this have I decided to immediately replace every disc I have, the examples of them going wrong have changed my ways. Thank you, excellent video.
