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)
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?
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!
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" 😁
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?
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 😀
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 👍👍👍
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.
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….
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.
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.
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.
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.
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.
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.
You proved the null hypothesis.......this is just as important as if you had proved that indeed, grinder discs will penetrate safety glasses. Brilliant.
@@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.
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.
Love the sprinkle of super fun and semi-scientific stuff. Possessed angle grinders with saw blades in them from a couple months ago (reshown at the end) was my top tier laughs.
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.
Cam, you missed an opportunity to change the black hawk branding on the cut off disc to black tail. 😉 All the thieves would still have your name on the video when they inevitably steal the slo-mo footage.
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.
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 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
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.
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.
A guy at work had 9” cutoff wheel discritigrate and hit him the glasses but didn’t in bed in them but cut him pretty good around his glasses but sadly for us blokes the biggest bit went through his jeans and hit his ballsack
I have seen a couple discs come apart before but it was because it was the wrong speed disc. Also I have had safety glasses save my eyes a couple times but not from flying disc parts.
So case closed, the Myth is BUSTED. You spun the disks 4x above their rated speed and they were fine. To get them to explode you needed to literally cut the disks up like a pizza, so clearly they are not turning into ninja stars busting through lens that are rated for impacts.
I’ve had a few explode on me previously, normally happens if you twist by mistake while cutting, but never had it injure me, it hurts when hitting skin but doesn’t break skin
So definitely can't talk about it going into lenses. But the disks will 100% come apart. Our chain sharpener disks have come apart before, it's usually once the disks are old and get pretty hot from extended use, though.
So, the end result of all this is that a disc pretty much won’t fail unless it is damaged in some way before you start using it; or, perhaps, if you damage it while in use and don’t stop grinding or cutting.
Remember to wear your safety glasses I almost got a chunk of pliers almost in my eye and I wasn't wearing safety glasses at the time and remember if it might go into your eye it will
I think the worst workshop accident video I've seen is a guy working on a lathe and his shirt get tangled up and he gets pulled through the lathe and sprayed up the wall it is absolutely horrific
Good safty glases with an actual rating on them go through some really rigorous testing to make sure they dont shatter and such. I'd be interested to see this test done with the cheapest most aliexpress glasses you can find. It might not make a difference but I'd be curious.
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.
I still have the blade shrapnel in a keep safe box that almost killed me. I never wore a face shield, and the one time i decided to put one on a 3 inch chunk lodged deep into the shield and literaly touched my eye lid. This is very rare but it does happen.
My brother had a disc shatter on him and his safety glasses did nothing to protect him. Mainly because they were sitting on the bench instead of being worn.
1. Use cheaper/worst quality discs, not diablo 2. Secure glasses better so they dont bounce around (humans have ears and glasses fit actual face better than watermelon) 3. Instead of dropping metal bar sideways, you need to replicate pinching motion, maybe pliers with some kind of jig
The only video of the disc being stuck in the PPE i believe is the first one I ever saw yeeears ago. It was a blurry russian video and it was a face-shield, not glasses. I believe it because that dude was shaking and actively bleeding.
If I did a thing was watching this, I'm sure he'd shed a tear seeing you shoot at an angle grinder going max speed with a nail gun. Edit: A tear of joy, that is.
I think most of the outlandish comments are people hoping they make it on your video. You should’ve also tested different brands to see which ones were the safest. Overall liked the video (gotta support the UA-cam algorithm). It would be sick if you could do this same test but with saw blades 1. It makes a great title and 2. If you almost die you can put it in the title for even more views.
Safety glasses are made from polycarbonate. Polycarbonate does not readily puncture. Safety glasses are design to flex and blow apart before they let _anything_ through. A bump to the eye is much preferable to shrapnel inside it. Turns out the engineers who design and approve PPE know what they're doing!
Had a chopsaw blade jam and then explode once before. Fortunately i always stand off to the side of the saw, months later im looking at the shop roof and wondering what this black half moon piece is stuck through the metal paneling. It was a chunk of that disc had flown 60 feet up and pierced the roof metal .
Had 2 of the discs explode but neither looked like these they completely blew apart. Have a nice scar on my wrist and a pair of eye glasses with shards in them but never looking perfectly like these.
Years ago i was working with a bricklayer. He was working on the chimney of a two story house. He picked up the angle grinder and holding it at waist height, switched it on. Before he even got to touch the brick he wanted to cut, the blade shattered. The shrapnel arc caught him across the groin. Slicing off his penis and one testical. Worse, it severed both arteries at the top of his legs. Luckily for him an off duty ER nurse lived across the street. She climbed up onto the roof and stabilised him for long enough to make it to the hospital. They managed to sew his penis back on and it worked. But he said that every time he got horny adter that, he remembered the accident and lost his enthusiasm! Do make sure that you never take the safety guard off and always ensure that it is between you and the blade.
The nail in the coffin that all of these are 100% fake is how much the glasses move/flex when they get hit by the disc fragment. If they actually got a shard embedded in their glasses, the glasses would have flexed and the shard would seriously damage their eye. It's just not possible that the shard pierces the glasses but doesn't touch anything behind them.
When all you have is a Nail, everything looks like a Gun
😂😂😂
Think about it.
This is the strangest epoxy table build video I've seen so far
It still might be the 2nd strangest after the denim epoxy table, but both are wonderful!
he might build one with the shrapnels of grinders XD
Angle Grinder damascus!
@ Cam has plenty of material for it after this video!
We need a warning about the nail gun. It made it very obvious I was watching UA-cam at my desk when I literally burst out loud laughing. Amazing.

The pinch will absolutely get the shatter he's looking for. The scars on my face can confirm that.
Any broken disc should be stopped by the metal guard. Your head shouldn't be anywhere in front of that guard.
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?
And if so, can you blame them?
@@OllavoTozzi Totally justified, TBH.
Been a metal worker for years, never has a single disc shatter, ever. I must be doing something very wrong....
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 😀
worked in construction for years. I have. But never seen an accident from it.
I have had two, not shatter, but throw chunks off.
Yes! You don't have a UA-cam channel where you feel compelled to fake a dramatic scenario!
My uncle had a disk shatter on him and it sliced open his cheek

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

You need an irregular surface like concrete. Thats how it happened to me. Bout pissed myself after the fact when i realized what almost happened
Thanks mate. I am now going to start using a full face shield instead of just using safety glasses when using a grinder.

25 yrs in construction and I never met anyone hurt by an exploding cutting disk...
LOL... your sense of humor is on point...
Blacktail Studios has become Mythbusters, I love it!
We had a guy at work who removed the guard to fit a bigger disk. It shattered and hit his nick. He's 6ft deep now, RIP.
I always thought it was one of the massive 12in blades that were actually sticking in peoples face and glasses when they blew up
I have seen a couple discs come apart before but it was because it was the wrong speed disc.

@@Lyonscarpentry I've only ever had them fall apart like the second test. Never had them crack necessarily.
… assuming the disk is manufactured to a certain quality standard (maybe don’t buy them on Temu)
@@georgwitting7865 DEWALT disc was the last one I had blow on me, I’d be too scared to try the cheap ones
You are so frickin' hilarious!!! 😂A true kid at heart. 🥰
So, the end result of all this is that a disc pretty much won’t fail unless it is damaged in some way before you start using it; or, perhaps, if you damage it while in use and don’t stop grinding or cutting.
You could hire a woodworker to build a half arc above the wheel to put a bunch of glasses on. 👍

I still have the blade shrapnel in a keep safe box that almost killed me. I never wore a face shield, and the one time i decided to put one on a 3 inch chunk lodged deep into the shield and literaly touched my eye lid. This is very rare but it does happen.
I’m going out on a limb and saying the disk through the safety glasses is so exceedingly rare it’s next to 0
My brother had a disc shatter on him and his safety glasses did nothing to protect him. Mainly because they were sitting on the bench instead of being worn.
Clutching his pearls ?! Hilarious ! 😆 😆😆
1. Use cheaper/worst quality discs, not diablo
2. Secure glasses better so they dont bounce around (humans have ears and glasses fit actual face better than watermelon)
3. Instead of dropping metal bar sideways, you need to replicate pinching motion, maybe pliers with some kind of jig
The only video of the disc being stuck in the PPE i believe is the first one I ever saw yeeears ago. It was a blurry russian video and it was a face-shield, not glasses. I believe it because that dude was shaking and actively bleeding.
If I did a thing was watching this, I'm sure he'd shed a tear seeing you shoot at an angle grinder going max speed with a nail gun.
Edit: A tear of joy, that is.
I think most of the outlandish comments are people hoping they make it on your video. You should’ve also tested different brands to see which ones were the safest. Overall liked the video (gotta support the UA-cam algorithm). It would be sick if you could do this same test but with saw blades 1. It makes a great title and 2. If you almost die you can put it in the title for even more views.
Safety glasses are made from polycarbonate. Polycarbonate does not readily puncture. Safety glasses are design to flex and blow apart before they let _anything_ through. A bump to the eye is much preferable to shrapnel inside it. Turns out the engineers who design and approve PPE know what they're doing!
Lmao the last angle grinder going haywire :D
@Mr. Hewes at 00:52 😅
Had a chopsaw blade jam and then explode once before. Fortunately i always stand off to the side of the saw, months later im looking at the shop roof and wondering what this black half moon piece is stuck through the metal paneling. It was a chunk of that disc had flown 60 feet up and pierced the roof metal .
Cam the KOR and mythbusters all in one who NU?
So great
You’re next influencer
And the first thing you do? Not wear safety glasses. Lol. Love the vids
Whether or not these videos were faked it is entirely possible. I know this from experience and am lucky to still have my eye
One day you’ll get Tom. Hang in there and keep trying.
In hospital near me they have a box of safety glasses with grinder disks stuck in them
5.25 that's not not pliers and a crescent wrench, that's two adjustable hammers
You’re in the danger zone Thumbs up 👍 good demo! Thanks
Had 2 of the discs explode but neither looked like these they completely blew apart. Have a nice scar on my wrist and a pair of eye glasses with shards in them but never looking perfectly like these.
Years ago i was working with a bricklayer.
He was working on the chimney of a two story house.
He picked up the angle grinder and holding it at waist height, switched it on.
Before he even got to touch the brick he wanted to cut, the blade shattered.
The shrapnel arc caught him across the groin. Slicing off his penis and one testical. Worse, it severed both arteries at the top of his legs.
Luckily for him an off duty ER nurse lived across the street. She climbed up onto the roof and stabilised him for long enough to make it to the hospital.
They managed to sew his penis back on and it worked. But he said that every time he got horny adter that, he remembered the accident and lost his enthusiasm!
Do make sure that you never take the safety guard off and always ensure that it is between you and the blade.
how about casting the broken pieces of the discs into an epoxy table ;)
keep on keeping on.
It’s almost like anzi standards where developed to stop nail guns
The nail in the coffin that all of these are 100% fake is how much the glasses move/flex when they get hit by the disc fragment. If they actually got a shard embedded in their glasses, the glasses would have flexed and the shard would seriously damage their eye. It's just not possible that the shard pierces the glasses but doesn't touch anything behind them.
Another fantastic video!!
I see people use cut off disk for grinding all the time. This will shatter it quite quickly.
This is the content I live for
Brilliant video , great slow motion . nice table , oh sorry wrong video hahahahahahahaha love the video .
