Sorry to call you out like this, but you made a huge mistake when filming this. As you can see on all the other influencers videos and pictures the discs always aims for the eyes with extreme precision, and since your watermelon doesn't have any eyes how are the discs supposed to know where to hit to ensure the maximum number of views?

We need a warning about the nail gun. It made it very obvious I was watching KZbin at my desk when I literally burst out loud laughing. Amazing.

[@MerlinZink]

a german youtuber had tested it with normal and safety glases (not sure if youtube made a english audioline (on the newes one they did)) his name is Jonas Winkler if your interestet about that experiment. (its called "Dieser Fehler hätte mir nie passieren dürfen" or on english "this mistake should never happend to me" or something like that)

[@chrisjones8876]

The amount the safety glasses flex when hit pretty much disproves those clips where the shard of blade has stopped millimetres from their eyeball

[@FAB1150]

It also shows how they're supposed to work Instead of breaking, they flex to absorb the impact and deflect the thing coming at them

[@claptree3217]

"Apparently, my lawyer and I do not recommend this". Best fucking quote ever.

[@alexthedonutslayer591]

Have you considered that maybe the reason why you see so many tiktoks of people with disk shards in their glasses is because angle grinders hate tiktokers and they're specifically gunning for them?

[@OllavoTozzi]

And if so, can you blame them?

[@SuperDavidEF]

@@OllavoTozzi Totally justified, TBH.

So the angle grinders are the heros we've needed all along but not the ones we deserve

[@BlacktailStudio]

Makes sense. Think about it.

[@tedteddington6223]

Been a metal worker for years, never has a single disc shatter, ever. I must be doing something very wrong....

[@aaakkk112]

I've had one shatter, I dropped the angle grinder on the floor and left it there since I didn't need it straight away, and when I later picked it up I had totally forgotten that I should have checked the disc.. I can tell you that the shrapnel can embed itself in to drywall 😀

[@livinagoodlife]

worked in construction for years. I have. But never seen an accident from it.

[@vincedibona4687]

I have had two, not shatter, but throw chunks off.

[@DavidWoods-r6o]

Yes! You don't have a KZbin channel where you feel compelled to fake a dramatic scenario!

[@lunatikas2720]

My uncle had a disk shatter on him and it sliced open his cheek

[@darrellpettis5823]

Great video! I've worked around angle grinders and I've had them blow up on me. I have never witnessed one going through a pair of safety glasses but I can tell you how to get the results you're looking for! When you pinch it as it's cutting it will explode get a piece of 1/4-in 4x4 angle start cutting into it about halfway in put pressure on it to where the metal pinches the blade and it will explode like you want!

[@christopherbedford9897]

I was wondering about that. Clearly the discs are made on a fiberglass substrate so it needs something to break several strands at once (like Cam did with the pliers) for it to break into peices, otherwise you get the disintegration scenario (as in the steel pendulum). I still wonder about how genuine the multiple tiktoks about this are though. Seems as Cam implied "a tiny bit coincidental" 😁

[@aaronwoodward8398]

The pinch will absolutely get the shatter he's looking for. The scars on my face can confirm that.

[@Trebor74]

Any broken disc should be stopped by the metal guard. Your head shouldn't be anywhere in front of that guard.

[@patdbus]

@@Trebor74 enough people out there that remove those guards, so that really shouldn be a problem for these scenarios. the real issue here should be that their face is fine, those glasses should flex considerably before puncturing, so even in its punctured it would have still hit your eye and with the force required for that you would have some other wounds as wel from the glasses digging in to your face.

[@nobodynone]

​​@@Trebor74 I had a former co-worker removing the metal guard to put a circular saw blade in it, It got pinched on a piece of wood that he was trying to saw and it jumped in his face and cut his lower jaw in two. It was one of the dumbest ideas you can have and I had no quarrel telling him that just like the guys who warned him before he did it, what an idiot.

[@RancidDragonProductions]

The fact that every video is a direct hit to the glasses with no scratches or cuts, or especially metal shards to the resr of the face is what we might call a clue as well.

[@robh.8214]

As a physiotherapist who has treated and evaluated a number of grinder disk injuries I can attest to the damage they can do. Some (possibly all) of the videos are fake. For it to only imbed right in the eye lens is highly improbable. Usually they shoot in all directions, with hands being the most common areas. I have seen where they explode and leave fine shrapnel in peoples faces that looks like freckles but is actually bits of the disk embedded and stained like a tattoo. Just about every person I have seen with these injuries has skin/soft tissue staining from the grinder grit or metal dust….

[@estyria777]

Oh that's a very good tell, thanks.

[@hulkthedane7542]

Back in the day, probably around 1990, I was polishing a silver bracelet on a stationary/bench rotary tool. The bracelet slipped out of my hand and flew up, hitting my ordinary glasses (no safety glasses were worn...) and pierced a hole through one of the lenses. I was unharmed, NO damage to my eyes or face, "just" a hole in my glasses..... The bracelet did NOT stick in the lens but fell down. I was 17 years old, and it was in an evening touth school shop - after this incident, it was mandatory to wear safety glasses when using those machines. Hitherto it was optional, and noone used them. Great video 👍👍👍

[@MrTapanes]

Was wondering what the kids would want for Christmas. Angle grinder and a nail gun. Thanks Cam!

[@matthewmattoon]

Don't forget the hammer, you don't want the kids to shoot the nail gun holding the safety back with their finger. That would be grossly irresponsible!

[@thepagan5432]

Full face protection is advisable, after a lifetime in engineering I have small pieces of steel stuck in my left cheek (face) and another in my lower neck which the hospital said would cause bigger scars if removed. They still show up on X-Rays and scans some 40 + years later.

[@bl4cksp1d3r]

good thingit's only your illusions, and not your safety glasses!

[@jarman_2000]

every time I've blown up a cutoff wheel (from it getting pinched in between the steel), The danger was always the little fragments hitting me in the eyes, never the big pieces. I always wear eye protection, gloves, and keep the wheel pointed away from my body as much as possible. Sometimes you have to cut in a weird position at a weird angle, but most of the time, all it take is a few extra seconds of brainstorming to keep your eyes, neck and balls out of the line of fire.

[@thehaze1972]

Thanks for writing my comment so I didn't have to. 🖖

[@BillionAIRCloths]

A little info about safety glasses, so long as they are legit, angle grinders will not penetrate them. The disk can't impart enough focused force to go through as it gets spread out over the large object. As well, the flex of the plastic material they use is meant to farther spread that energy. A nail gun or high powered pellet gun will go straight through at point blank. The farther you are, the less likely a penatration will be. This is also why paintball and airsoft have different standards for their safety equipment.

[@davidsmith2655]

This is exactly correct. Current standards for PPE are that they absorb and spread out impact force. Something that would allow penetration risks multiplying the injury and damage. Just like "cheap" foreign cars that crumble under small speed impacts, better the object get smashed up than the human being protected by it.

[@freethebirds3578]

@@davidsmith2655 Like watching a race car disintegrate when they crash. The energy goes with the fragments away from the driver.

[@brendancarson8587]

I've had many disks explode. While wearing safety glasses and other times safety squints. Never had a chunk stick into a poly carbonate lens. Many flesh wounds though. Fun content keep it up!. Between this and the builds it's a good mix!

[@user-px9bd]

"Safety squints" 🤣

[@brucemcelroy3186]

I use multiple air grinders daily as a trailer mechanic. this has been a great ad for BHA. I have some of their cut-off wheels and they work pretty well. good to see that they stay together. I'll never spin them that fast.

[@amaggard14]

I’ve actually seen discs break before working as a construction worker. Normally I think it happens when cutting something and accidentally putting force on the side of the disc, like if you accidentally turn the grinder in the middle of a cut. Just pointing that out because the video made it seem like they are indestructible unless you shoot it with a nail gun or break it. Obviously though the tiktok videos are bs, which is just the nature of tiktok.

[@lauig]

Wish i had the same confidence to go through life facing dangers as that daredevil. What a true brave one this watermelon.

[@EggMcnuggets]

"I really thought this was the video that would land you Tom" is ABSOLUTE gold.😂😂😂😂

[@ToysForTheGods]

I have had a couple embed themselves into my legs over the years, which hurts like hell. I tend to not put my face in the path of destruction if I can avoid it, but in the 20 foot ceiling of my old shop, to this day is half a disc embedded from a 4" angle grinder, now the ceiling is just 4 inch hard spray foam, but keep in mind it is 20' in the air if it had hit someone in the face it would have been tragic. Was a new kid on the job that didn't listen very well but I think he had to go home and change is panties that day. Cool video, its just so important to emphasis safe use of these tools and please wear personal protection.

[@jackmclane1826]

The bounce shot was actually more powerful than a direct hit would've been. Because the disc piece rotated faster than it flew away. So it converted some rotational energy into even more speed right before the impact

[@jeffreyyoder7461]

Ah, “down” time at Blacktail Studios, lol. At least you’re not staying idle ;). You can tell you were once in emergency services. We play a bit differently. Seriously, though, thanks for the vid and I look forward to some of your future equipment tests.

[@DrivingWithJake]

Guy I worked with almost died from that hitting his jug. Made it to the safety horn before passing out. For the slowmo use a slower disk and spin it up high speed and see what it does. I believe that's what happen had a normal grinder disk on a air tool spinning much quicker and snap.

[@tjshort9124]

1.Dont know who you guys are but I like the brcc gear 2. If you take a trigger activated ramset and a box wrench you can put the wrench over the end of said ramset to pull back

[@doseofreality100]

I've been around metal workers/welders for.... 12 years - I've only ever heard of 1 disc ever breaking. And it got lodged into the guy's cheekbone. Because his safety glasses just flexed and deflected the shard down into his cheek. He got in trouble/yelled at after the fact.... for not wearing a face shield as one should (and as he was trained/told to) when using an angle grinder.

[@DONCG10]

So something similar happened to a coworker of mine while we both worked in the same mechanic shop. he was using my air grinder while cutting off some bolts on an exhaust. He wanted to wear my welding mask because it had a grinding mode and I let him. About 15 seconds in all I hear is the air grinder speed up and then a pop and my coworker going S**t. The welding mask saved him from eating grinding disk in the face but it did punch a single small hole into my welding mask and bruised his nose. I still have the mask to this day and he now refuses to grind anything without a welding mask XD

[@sticustom]

I put an angle grinder down on a table whilst it was running down, it fell off, hit the concrete floor and the disc exploded. A piece hit me in the leg and cut my leg enough to bleed. No stitches. As for the angle grinder taking off like it did at the end, I’ve seen that with a 9 inch grinder. Three blokes became Olympic high jumpers.

[@seanchristie7150]

Fantastic episode, loved the epoxy pour. Crazy how much abuse the discs take before destroying themselves

[@bigv6724]

Should've scored that sticker on top. Thankfully it helps keeping it all together instead of exploding. The bigger disc's would've gotten you a better result too.

[@LawF250]

I've never had a cut-off wheel come apart. Maybe because i don't but cheap ones, and also use them correctly. I've gone through hundreds of them without issue.

[@norbertnagy5514]

Also, you probably dont spin it at tens of thousands of rpm and dont smash it, throw it nonchalantly to make cracks in it, so it disintegrates sooner.

[@terencemerritt]

Malecki, I think you need to let Cam test the shop shades my guy

[@napalmholocaust9093]

Idk what the thumb was, thought paint like for football and glare. I keep the guard on so I can set it down without it flying across the table. Worst damage I've gotten was getting a knuckle sliced open pretty good on the hand holding whatever it was when it shattered. Bust them occasionally. A 7inch disk is where they start getting dangerous, not the slim 4.5

[@Jnichols77]

I was cutting a body mount off my race car with a grinder and it bound up and came out of my hand. Knocked my safety glasses off and cut from my right nostril all the way over my left eye. 86 total stitches. The handle of the grinder hit hard enough to break my nose and orbital bone. I also just started a new job and didn’t have insurance. To make things a little worse, the disk didn’t appear broken and the next time my dad went to use the grinder a couple days later it came apart on him and cut his cheek.

[@deahy474]

We have a guy at work from Northern England (he prefers the term Scotland) he would be a quivering mess now after seeing all those discs wasted

[@nicgurkweitz389]

When I was a welding student learning to use a grinder and a cutting wheel for the first time I had one explode on me, I was wearing my leathers and face shield, it exploded into my chest, went up my leathers into and bouncing off my face shield, I did that the first week in training when I was at Job Corps. One week later another student did something similar but it lodged into the top of his thigh because he wasn't using his bottom leathers. To this day I still will never not use PPE, even though it's been 17 years. It just takes once to have your life changed forever. I live too far from any hospital to take any chances. If you want the proper way to make them explode you need to create a cut closer to the tightening nut, have a piece of metal puncture the disc while spinning as close as you can to the nut and it will explode. The discs that explode the best have a hump where the tightening nut is, if you puncture that hump while it's spinning it will most definitely explode. They're the worst ones to use as they're the most dangerous in my opinion. The flat ones don't explode as well in my opinion.

[@StephenNetherton]

Polycarbonate is designed to flex to absorb/deflect the damage. Some awesome comments on a superb video. Thanks for sharing!

[@pocketchange3543]

I've had the opposite happen. While wearing a full face shield the cut off wheel broke and a piece bounced off me, bounced off the inside of the face shield and embedded into my eye.

[@ossieljuarez1936]

I've personally had a chunk of a cut off disc hit me in the chest. It left a bruise and a need of change of shorts. After that I stopped using the cheap discs from a certain store that shall not be named.

[@swissforge8627]

Thank you for calling out this bullshit! I've seen some of these posts shared even in the fabricator/welder communities. They give a totally wrong impression of how a cutting disc behaves when breaking and thus has the potential to do harm. I always thought it's odd that none of my discs ever just explode despite me sometimes using them in ways not recommended. But other people constantly tell horror stories about them

[@marksmallman4572]

Biggest danger is nicking a finger, luckily, cauterises the would at the same time, I know!

[@swissforge8627]

@marksmallman4572 Yeah, but keeping the protective guard on there and in the right position pretty much negates the issue of reaching into the blade. Also helps a lot in terms of sparks and debris. I only remove it in really tight situations, which is usually where accidents happen ironically lol

[@bandana_girl6507]

As someone who used to work in an ER with ophthalmology, people underestimate just how small something can be to still cause a big issue. We even had someone who had major issues not from the general facial trauma from something that knocked his safety glasses up but from the little tiny splinter/sliver that was just late enough to get in to his eye. I never heard the full story as to what happened or what material he actually got in there, but IIRC, the main bit hit the brow of his safety glasses

[@Talinthon]

My mechanic got a split upper lip from a zip disc coming apart on him. It left one heck of a scar that makes him look like he was on the losing end of a knife fight. He was not wearing a face shield. I've had 8" x 1" surface grinder wheels come apart on me twice. Both times were my fault - first time I jammed a diamond dresser between the work piece and the wheel while my nose was 6" away from it and second time I forgot to do a ring test (lightly tap the wheel with a wrench listening for a ting or a tunk with tunk meaning the wheel is cracked and needs to be thrown out) before putting it on.

[@JosGeerink]

Care to explain?

[@kalyky]

@@JosGeerink He is talking is terms of a statistical hypothesis test. In this case, the null hypothesis is that the cutoff wheel fragments will not pierce the safety glasses as seen in the other media. 'We' are assuming that those other videos are fraudulent to an extent. The alternative hypothesis in this that wheel fragments can dramatically penetrate safety glasses as seen in the viral Tiktok videos. You can't really "prove" a hypothesis (very strictly speaking, (and this isn't a science paper)), but this video's experiment did not provide enough evidence for us to 'accept' the alternative hypothesis instead of the null. Rick is saying that although we didn't have the same result as other videos showed, and we are still just assuming they are fabricated to an extent, that it is still a useful result: We have gained some evidence that proper safety glasses can't just be stabbed through by a shattered cutoff wheel.

[@graeme0]

When I was an apprentice I used a full face mask as I wear glasses. One day a 3" milling bit exploded into my face, it bounced off me knocking me backwards and a chunk imbedded itself onto a pillar. Scratched the face shield and bruised me but nothing more (apart from a very angry apprenitce master!!). A valuable lesson in PPE... and listening to the lessons downcut milling and feed rates...!!!

[@LogicalNiko]

I think the issue with the cuts is that you are creating most of the edges with the tin snips so they are not going to be as sharp and pointy as some made by natural fractures. Then with the angle grinder test the metal bar is now pulverizing the disc material into small bits which will not have enough mass to penetrate deeply. Inducing natural fractures is not very easy. Generally you need to induce a wobble in the material to where waves formed in the disk overcome the material strength. Possibly mounting the blade off axis might help. Something like introducing a spacer on one portion of the blade forcing it off the axis of rotation.

[@MagixianX1]

Had this happened to me twice at full speed so far, once directly into where my eye was. Always have a face shield on, theyre the same material and thickness as the safety glasses. Just like yours its a decent scratch and you feel your head knocked back a bit. One shattered and hit my thumb nail, again no bloodshed but it will bruise and hurt.

[@mattelias721]

This is decent content, Cam. If nothing else came of it, you demonstrated eye PPE works. I've had discs vaporize and was glad I had glasses on, but I do agree the number 'influencer' stuff is staged. The key thing here is that those safety glasses you used were curved, so you'd have to have a literal perfect strike - ALL the mass of the fragment forcing into ONE perfect point at a EXACT 90-degree angle of inflection (90 in three dimensions, too). Even then, as someone below pointed out, that fragment likely doesn't have the mass to penetrate it. Source: former Army guy with ballistics knowledge.

[@estyria777]

Poor watermelon xD I generally don't play with power tools, and you won't catch me messing with a grinder ever. That said, do wear your safety glasses. My Dad was a transmission tech for a very long time, and when I was a little girl he had a shard of metal fly right into his eye. The doctor saved his eye, and his sight, and for the rest of his life he had half a cat-eye pupil. It was pointy at the top. It lives in my memory any time I'm about to do something remotely risky.

I think the issue with the cuts is that you are creating most of the edges with the tin snips so they are not going to be as sharp and pointy as some made by natural fractures. Then with the angle grinder test the metal bar is now pulverizing the disc material into small bits which will not have enough mass to penetrate deeply. Inducing natural fractures is not very easy. In most materials it happens after the material starts deflecting off axis putting load in directions the disc was not designed to support. The only thing I could think of is somehow inducing a bend or wobble at very high speed would help facilitate this situation…how? No clue.
