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?
Have you ever done heads or tails and gotten one side multiple times only to your choice to the other and then the coin flips to your original guess? I’m gonna say that’s probably what would happen here. There’s not really a good predictable way to how it’s going to break even if it breaks in a similar manner multiple times
@@gotyouchip1179 It breaks very similarly every time. You can see one shard go right over the top of the melon in pretty much every attempt. Stacking another melon on top wearing another pair of glasses would catch that one. The other large portion of the disc goes pretty much straight down every time. Again, putting another pair of glasses there would catch that. To me, this video feels like it was made by someone who wants to call out some fake tiktoks and doesn't actually care whether they get the evidence they need to do it. I agree with him, those tiktoks are pretty obviously faked, but if you're gonna make a video like this to collect evidence, you should actually bother to collect some evidence.
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.
I mean, yes, it's fake, but we all can agree that as long as it makes the point across that everyone should wear those glasses, the fake stuff is kinda worth it?
@Acuas to a degree. At some point it becomes a problem where people totally don't believe it's possible at all and don't wear safety equipment, or they try and recreate it a dangerous way. So, that can go from being awareness through satire to a hazard from apathy.

@@Acuas you don't need to lie to show why PPE is a good idea. Just look up how optometrists remove metal fragments from eyeballs. Its kind of fucking horrible.
The rest of you are missing the point chris is making: even flesh will flex enough that if the blade shard truly came to rest that far from their eye, during the hit it would have been inside their eye. Obviously it depends on the safety glasses, but none are going to have sub 5 mm flex with a hit of that magnitude. Plus I'd expect bruising around the bridge of the nose and rim of the glasses if a shard unloaded all of its kinetic energy into the glasses (and by extension the parts of the face the glasses rest on)
@@MrFlarespeed I agree 100%, there is no way that disk would embed in the lens and still not hit your eye or some other part of your face (if you were lucky). All done for clicks and likes!

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" 😁

9:26 Unironically you could probably sell this clip to the company making these glasses advertisement team and or gain a long time sponsor too It would make me wanna buy those glasses if i saw it in an advertisement
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.
Grinding disks will crumble, they are just cemented together aluminum oxide. A grinding disk penetrating polycarbonate was always an incredibly stupid thing for anyone to believe.
I always doubted this too. How can a disk which you can break in your hands penetrate something super tough and flexible. I always thought there wouldn’t be enough weight behind it.
@@therustymusket Certainly not impossible for softer things to penetrate a harder material. a .308 round made of copper and lead can penetrate 1/8" mild steel all day. That said, with certified safety standard glasses, I agree it's suuuuper unlikely for a disc to penetrate.
Thanks for making this video 😂 I’ve been telling people for years that it would be impossible for a grinder disk to stick in to safety glasses… but I couldn’t prove it sooo people just shrugged and believed there inter-web videos..
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.
I am blind in one eye from a guitar string accident. I can't tell you how many times I've seen instances of people using power tools with no safety glasses when they should be using them. Trust me when I tell you that if you even think that something might hit you in the eye, either take precautions or wear safety glasses. It's not worth losing your sight.
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 👍👍👍
The way that angle grinder at the very end seemed to come alive and come after you with a vengeance made me burst out laughing. That's great comedic content right there!
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!
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.
i always learned not to wear gloves with spinning tools as they pose the risk to suck your gloved hand in I always sweat bullets when using the angle grinder cuz it is just such a scary powerful tool stay safe
@@Moritz___ Large stationary tools, yes, I get that. but something small that can fall on your hand like an angle grinder? Gloves all day. You wont be sucked into a hand tool the same way you would a lathe or mill or something. I've seen peoples' hands saved several times from a grinding disk or cutoff wheel because they had on leather work gloves (myself included). If the glove fits your hand properly it's safer than not having them. At least that was the belief in my workplace
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 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 morbidly curious side of me really wants to google those angle grinder accidents. The sane and VERY queasy side of me is so far winning out, but not by a lot...
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.
They should try to impact the disc with a sharp edge to shatter it, emulating it breaking off while cutting. Otherwise the energy isn't transferred correctly.
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.
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.
I was apprentice in bodyworkshop and grinded the car body panel with disk horizontally, as it goes disk exploded in my face but as i was wearing safety glases no scratches from it. Had similar accident this year then grinding metal with cutting disk. These disks are not ment to be used for grinding i guess.
I’ll never forget my sons face the first time we worked on a deck together and I’m holding the safety on the framing nailer and unloading a shock of nails into the woods. He still talks about it 😂
I have been aware of your content in the past. But this was the first video of yours. I paid any attention to, and the past week after seeing that video, I watched all your videos
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.
I'm equally watching these videos for the craftmanship, as for the slams Cam put down the trolls with. It's most often a 'Chef's kiss' or 'Salt bae'. I think I've seen a 'Sad trombone' once, but we don't talk about that...
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 personally know a person who this happened to, but it was one of those swiss cheese cases where all the holes line up like they teach up on Human Factos training. The company cheaped out on discs, he was using the wrong disc on the wrong material, the safe guard had been removed, and the angle grinder also had speed control issues, to top it all off he was not using PPE. The disc burst and he lost his right eye. My dad was a sheet metal worker for almost 50 years, he always taught me to have the utmost respect for the angle grinder when using it. It's one of the tools I refuse to use actually, even when I'm messing around with my Dremel i use my normal glass AND a pair of rated PPE safety googles.
1985, 8th grade metal shop. The shop had long tables, topped with sheet metal, with a bench vise at each end. The teacher had the whole class around one table so he could demonstrate the proper use of a center punch. He placed a piece of metal on the vice's anvil flat, held the punch firmly and gave it a solid hit with a hammer. Next was don't do it like this - holding it between finger and thumb tip and giving it a light tap. The intent was to have the punch fall to the table top. Somehow that time the way it slipped it shot down the table, ricocheted off the sheet metal and up. Straight as a bullet it went through the left glass lens of the safety glasses a boy was wearing. The way he was leaning over and had his head turned, the punch completely missed his head. He didn't even get glass in his eye. The teacher stood there for a second with a shocked look on his face, then dragged the student to the emergency eye wash station. Later he said he'd been doing that demonstration for years and nothing like that had ever happened. From then on the plastic goggles weren't so dorky looking. We'd all wanted to grab pairs of the glasses at the start of each class.
I did search, and from now on, I'm wearing safety glasses, a face shield, a neck guard, a hard hat, and leather gloves. Those injuries are horrific, I'm not taking any chances now.
@@eboshi1231 truly the best way to get people to wear the appropriate PPE will always be to show them what happens/what it looks like if you dont wear said PPE
I am so happy to see this video, i just got done ranting to my girlfried about these videos. Where are the other videos of people getting hit in the 80% of their face not protected?😂
@@bobbygetsbanned6049 No it's not. But nobody has videos of their otherwise uncovered face getting hit, which further supports the face video theory. That was my point... Obviously blindness is the main concern.

Love this content, but please PLEASE wear safety glasses while doing stuff like this. That one at 5:20 that launched over over the shop could have gone into the shop and your face D=
@djmartin4776 i bought some on Amazon. 25€ for 50 disks. Ended up in telling Amazon they were dangerous and thrown them away. 2 colleges got hurt in the mean time.
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.
As someone who is not a certified mechanic; unless you consider training hours from UA-cam university reputable this day and age. I did not clutch my pearls when I saw you using a pair of pliers and a adjustable wrench. Great video as always sir!
Yes indeed. I have seen an instance in my shop where a single strand of wire flew off the wheel, went through the guy's jeans, into his skin, and then turn 90 degrees after hitting his shin bone.
I only use dremel cutoff wheels, and safety glasses have saved my eyes twice over the years. Never had anything embed in the glasses, but they definitely got hit and left a nice gouge. For a long time, I kept one of those damaged pairs to show to anyone who questioned why I wore safety glasses. "Its only a little 1" cutting disk. What's it gonna do?" *shows damaged glasses* "This"
About 9 years ago I had a drill bit bind up and explode and one of the fragments pinged off my safety glasses. I immediately hit the e-stop button and went and sat down for a few minutes and thought about just how glad I was to have my safety glasses on. It only left a tiny little mark in the glasses.
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
Back in the 70s, when I was a student, I had a vacation job working for a builder. One day, I was stood on a reinforced concrete lintel, cutting it to length with a 10” (?) electric grinder. Something happened to make part of the blade shatter, the blade then caught on the lintel and the grinder span out of my hands between my legs. My jeans were torn through to the skin just below my family jewels, but no actual skin was broken, which was lucky, as the likely point of impact would have been in the region of my femoral artery. The disk didn’t actually break, it just kinda shattered in a small area, the disk being held together by the integrated reinforcement. I just now had the thought, though not at the time, that I should have gone to play roulette right away!
at the moment 9:35 you can see that the angle grinder has protection against splinters on the operator's side, and if it really broke all the bits would fly, which in the case of the tiktok video didn't happen, and if in fact that shrapnel actually hit the glasses protection, the impact to do that penetration damage would cause significant damage to the operator anyway, as in the video they are without any scratches, so... FAKE AF
I was using a thin wheel angle grinder with face shield and gloves. The disk exploded and shocked me. Not only did the disk not penetrate my face shield, but a chunk of disk hit my hand and it didn’t really even hurt with my glove on. Didn’t draw blood or leave a bruise, and these weren’t heavy duty gloves, just normal work gloves. It was scary, but I think PPE just protects you, as the name implies.
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.
I will say I did a similar test with safety glasses and paintball goggles a long time ago, except testing for shooting safety. Blasted them from nearly point blank with high power air rifles and they were extremely resistant. I think it took something like 20 shots with a 1/8" grouping before we got penetration. The lens materials are designed to distort/deflect, not break/penetrate.
The reason you see TikToks of disk shards in safety glasses is because natural selection eliminates the ones that miss the glasses/those who aren’t wearing them before they can post something about it.
Even regular glasses are better than none at all! Used to repair pneumatic nailers and staplers and almost lost my eye to it. Disassembled a valve and the spring popped right up and hit me in glasses. Ended up indenting the glasses but better than an eye patch. Always wear safety protection, safety is number one priority.
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.
I’ve had a cut off disc break on me before and it was my fault for twisting it slightly, but I’ve never had anything fly at my face from an angle grinder. A bench grinder vibrated apart my dressing tool and sent a hardened star shaped ring of steel into my safety glasses. That one almost penetrated; there are two distinct holes in the plastic lens of one eye spaced about an eighth inch apart

Well… I think we both know what happens if it hits the other parts of your face.
Underrated comment
To be that guy, the ones that go everywhere else are in the hospital shortly after and are not allowed on tiktok under gore rules.
The amount the safety glasses flex when hit pretty much disproves those clips where the shard of blade has stopped millimetres from their eyeball
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
Eh, there are a million different glasses, of varying thickness and varying polymer blends. Some flex, some don't, some are cheap as hell some not.
All of them were different types of plastics, thicknesses and styles
The rest of you are missing the point chris is making: even flesh will flex enough that if the blade shard truly came to rest that far from their eye, during the hit it would have been inside their eye. Obviously it depends on the safety glasses, but none are going to have sub 5 mm flex with a hit of that magnitude.

9:26 Unironically you could probably sell this clip to the company making these glasses advertisement team and or gain a long time sponsor too
It would make me wanna buy those glasses if i saw it in an advertisement
it even has the brand name perfectly upright during the impact, it would be one hell of a clip for a commercial
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.
@@davidsmith2655 Like watching a race car disintegrate when they crash. The energy goes with the fragments away from the driver.
Grinding disks will crumble, they are just cemented together aluminum oxide. A grinding disk penetrating polycarbonate was always an incredibly stupid thing for anyone to believe.
I always doubted this too. How can a disk which you can break in your hands penetrate something super tough and flexible. I always thought there wouldn’t be enough weight behind it.
@@therustymusket Certainly not impossible for softer things to penetrate a harder material. a .308 round made of copper and lead can penetrate 1/8" mild steel all day.
That said, with certified safety standard glasses, I agree it's suuuuper unlikely for a disc to penetrate.
Thanks for making this video 😂 I’ve been telling people for years that it would be impossible for a grinder disk to stick in to safety glasses… but I couldn’t prove it sooo people just shrugged and believed there inter-web videos..
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.
Lol the proper way to explode a grinder blade? Those words don't belong together.
I am blind in one eye from a guitar string accident. I can't tell you how many times I've seen instances of people using power tools with no safety glasses when they should be using them. Trust me when I tell you that if you even think that something might hit you in the eye, either take precautions or wear safety glasses. It's not worth losing your sight.
Did the high E string get you during tuning? Or did you take a dirty g-string to the cryball while performing at a strip club?
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 👍👍👍
You were both really unlucky and incredibly lucky at the same time.
The way that angle grinder at the very end seemed to come alive and come after you with a vengeance made me burst out laughing. That's great comedic content right there!
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!
"Safety squints" 🤣
So safety squints work? 😂
Joking, anyone reading this, use proper safety gear.
Nothing gets through the squint
1:41 high quality disk😂
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.
Thanks for writing my comment so I didn't have to. 🖖
i always learned not to wear gloves with spinning tools as they pose the risk to suck your gloved hand in
I always sweat bullets when using the angle grinder cuz it is just such a scary powerful tool
stay safe
@@Moritz___ Large stationary tools, yes, I get that. but something small that can fall on your hand like an angle grinder? Gloves all day. You wont be sucked into a hand tool the same way you would a lathe or mill or something. I've seen peoples' hands saved several times from a grinding disk or cutoff wheel because they had on leather work gloves (myself included). If the glove fits your hand properly it's safer than not having them. At least that was the belief in my workplace
"and balls"
This is the wisest guy in the comment section
With every slowmo shot my mind filled the space with the slowmo guys background music/sound
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.
Did this unnamed store's name happen to rhyme with "Barber Weight"?
Therapist: “So, what keeps you up at night?”
Cam: “I lay there thinking about how I’m going to secure Tom’s subscription on UA-cam.”
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 morbidly curious side of me really wants to google those angle grinder accidents. The sane and VERY queasy side of me is so far winning out, but not by a lot...
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.
They should try to impact the disc with a sharp edge to shatter it, emulating it breaking off while cutting. Otherwise the energy isn't transferred correctly.
Love your usual wood working videos but it’s refreshing to see you do some fun stuff aswell. All your contents really interesting man keep it up 👍🏻
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.
1:06
oh the irony of doing this without safety glasses on
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.
I was apprentice in bodyworkshop and grinded the car body panel with disk horizontally, as it goes disk exploded in my face but as i was wearing safety glases no scratches from it. Had similar accident this year then grinding metal with cutting disk. These disks are not ment to be used for grinding i guess.
Yeah, full face shield for the win!
i can recover from a disk in my cheek.. eyes not so much..
I’ll never forget my sons face the first time we worked on a deck together and I’m holding the safety on the framing nailer and unloading a shock of nails into the woods. He still talks about it 😂
Nail gun looked fun till the wife gets a suspicious flat tyre
I have been aware of your content in the past. But this was the first video of yours. I paid any attention to, and the past week after seeing that video, I watched all your videos
"I really thought this was the video that would land you Tom" is ABSOLUTE gold.😂😂😂😂
Hi Cam love the videos, had a good laugh about how some points in video your neighbours number is blurred and other it’s not 😂
@10:15 - you said “pee pee”.
Yes. Yes he did. He also said e as in e for everybody. Pee pee for everybody.
Hehehe
Your videos calm my anxiety. Idk why
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.
Who & how did they stop his bleeding ?
I'm equally watching these videos for the craftmanship, as for the slams Cam put down the trolls with. It's most often a 'Chef's kiss' or 'Salt bae'. I think I've seen a 'Sad trombone' once, but we don't talk about that...
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.
alllmost got my old EMS helicopter company to land in my yard to be on duty for this video.
I personally know a person who this happened to, but it was one of those swiss cheese cases where all the holes line up like they teach up on Human Factos training.
The company cheaped out on discs, he was using the wrong disc on the wrong material, the safe guard had been removed, and the angle grinder also had speed control issues, to top it all off he was not using PPE.
The disc burst and he lost his right eye.
My dad was a sheet metal worker for almost 50 years, he always taught me to have the utmost respect for the angle grinder when using it. It's one of the tools I refuse to use actually, even when I'm messing around with my Dremel i use my normal glass AND a pair of rated PPE safety googles.
Blacktail Studios has become Mythbusters, I love it!
1985, 8th grade metal shop. The shop had long tables, topped with sheet metal, with a bench vise at each end. The teacher had the whole class around one table so he could demonstrate the proper use of a center punch. He placed a piece of metal on the vice's anvil flat, held the punch firmly and gave it a solid hit with a hammer. Next was don't do it like this - holding it between finger and thumb tip and giving it a light tap.
The intent was to have the punch fall to the table top. Somehow that time the way it slipped it shot down the table, ricocheted off the sheet metal and up. Straight as a bullet it went through the left glass lens of the safety glasses a boy was wearing. The way he was leaning over and had his head turned, the punch completely missed his head. He didn't even get glass in his eye.
The teacher stood there for a second with a shocked look on his face, then dragged the student to the emergency eye wash station. Later he said he'd been doing that demonstration for years and nothing like that had ever happened.
From then on the plastic goggles weren't so dorky looking. We'd all wanted to grab pairs of the glasses at the start of each class.
Do not search for that 7:02
I did search, and from now on, I'm wearing safety glasses, a face shield, a neck guard, a hard hat, and leather gloves. Those injuries are horrific, I'm not taking any chances now.
@@eboshi1231 truly the best way to get people to wear the appropriate PPE will always be to show them what happens/what it looks like if you dont wear said PPE
Too late 😭😭😭😭😭🙏
👏@@eboshi1231
safety regulations are often written with blood
I am so happy to see this video, i just got done ranting to my girlfried about these videos. Where are the other videos of people getting hit in the 80% of their face not protected?😂
Was there ever a video of someone getting hit in the mouth or cheek? How do they know to always go straight for the eyes? lol.
That's the real risk, getting a nasty scar on your face.
@@bobbygetsbanned6049 No it's not. But nobody has videos of their otherwise uncovered face getting hit, which further supports the face video theory. That was my point... Obviously blindness is the main concern.
Sehr lehrreiche Tests die du da machst, diese Unfälle entsprechen der Tatsache, passiert meistens wenn man bei der Arbeit verkanntet. Bitte immer ausreichende gute psa benutzen. Euere Gesundheit, und euer Leben wird es euch Danken. Bitte mehr Info über solche Dinge 😊
Love this content, but please PLEASE wear safety glasses while doing stuff like this. That one at 5:20 that launched over over the shop could have gone into the shop and your face D=
Exactly! They are testing protection without protection...
Those things will shoot put extremely fast and have a chance at coming directly to them
This is a GREAT video demonstrating the benefits of safety glasses.
I never would have thought that they would have survived or protected so well.
9:20 maybe you are using branded disks and accidents require low price ?
My thoughts exactly. I've heard stories of em coming apart and injuring people and I think it involves dollar store disks
@djmartin4776 i bought some on Amazon. 25€ for 50 disks. Ended up in telling Amazon they were dangerous and thrown them away. 2 colleges got hurt in the mean time.
0:54 my guy passed the vibe check 🤣🤣
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.
LOL - the helmet for the nail gun shots 😂
Polycarbonate is designed to flex to absorb/deflect the damage. Some awesome comments on a superb video. Thanks for sharing!
😂 the nail gun. Absolutely amazing.
Malecki, I think you need to let Cam test the shop shades my guy
As someone who is not a certified mechanic; unless you consider training hours from UA-cam university reputable this day and age. I did not clutch my pearls when I saw you using a pair of pliers and a adjustable wrench. Great video as always sir!
4:44 bounced but didn't look like it lost momentum
Any bounce is a loss of momentum. It causes it to roll off more easily, especially with the angle of the bounce.
The nail gun bit is peak "Boys will be boys" ROFL. loved it
2:06 LMAO.
“As long as you rip it in half, these things break easily!” 😂😂😂🤓
Wire wheels are far
more wicked. I’ve had wire stuck in places I don’t care to mention.
Yup, wicked is a good way to describe wire wheels.
Yes indeed. I have seen an instance in my shop where a single strand of wire flew off the wheel, went through the guy's jeans, into his skin, and then turn 90 degrees after hitting his shin bone.
I only use dremel cutoff wheels, and safety glasses have saved my eyes twice over the years. Never had anything embed in the glasses, but they definitely got hit and left a nice gouge.
For a long time, I kept one of those damaged pairs to show to anyone who questioned why I wore safety glasses. "Its only a little 1" cutting disk. What's it gonna do?" *shows damaged glasses* "This"
@Mr. Hewes at 00:52 😅
About 9 years ago I had a drill bit bind up and explode and one of the fragments pinged off my safety glasses. I immediately hit the e-stop button and went and sat down for a few minutes and thought about just how glad I was to have my safety glasses on. It only left a tiny little mark in the glasses.
1:39 That looks like sooo much fun!
one of my favorite videos I've seen in a long time!
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
Lololololol
Back in the 70s, when I was a student, I had a vacation job working for a builder. One day, I was stood on a reinforced concrete lintel, cutting it to length with a 10” (?) electric grinder. Something happened to make part of the blade shatter, the blade then caught on the lintel and the grinder span out of my hands between my legs. My jeans were torn through to the skin just below my family jewels, but no actual skin was broken, which was lucky, as the likely point of impact would have been in the region of my femoral artery.
The disk didn’t actually break, it just kinda shattered in a small area, the disk being held together by the integrated reinforcement.
I just now had the thought, though not at the time, that I should have gone to play roulette right away!
at the moment 9:35 you can see that the angle grinder has protection against splinters on the operator's side, and if it really broke all the bits would fly, which in the case of the tiktok video didn't happen, and if in fact that shrapnel actually hit the glasses protection, the impact to do that penetration damage would cause significant damage to the operator anyway, as in the video they are without any scratches, so... FAKE AF
Cool video. You should use a reference measure to get the velocity of the flying pieces.
1:57 In Latin America we also know them as:
UNITED ARMED X'DX'DX'D
I was using a thin wheel angle grinder with face shield and gloves. The disk exploded and shocked me. Not only did the disk not penetrate my face shield, but a chunk of disk hit my hand and it didn’t really even hurt with my glove on. Didn’t draw blood or leave a bruise, and these weren’t heavy duty gloves, just normal work gloves. It was scary, but I think PPE just protects you, as the name implies.
I love how you aren't wearing safety glasses while demonstrating their necessity.
Priceless, as always your nimble mind hits the spot, very entertaining
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.
@@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
I will say I did a similar test with safety glasses and paintball goggles a long time ago, except testing for shooting safety. Blasted them from nearly point blank with high power air rifles and they were extremely resistant. I think it took something like 20 shots with a 1/8" grouping before we got penetration. The lens materials are designed to distort/deflect, not break/penetrate.
The reason you see TikToks of disk shards in safety glasses is because natural selection eliminates the ones that miss the glasses/those who aren’t wearing them before they can post something about it.
I like the enthusiasm but lol no.
@ funny how they don’t make tiktoks about it when the disk pierces their skull
The pliers and crescent wrench sums this channel up.
5:02 that would be me.
Even regular glasses are better than none at all! Used to repair pneumatic nailers and staplers and almost lost my eye to it. Disassembled a valve and the spring popped right up and hit me in glasses. Ended up indenting the glasses but better than an eye patch. Always wear safety protection, safety is number one priority.
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.
The universe that day pointed at you and said
F you in particular

Great video. Don't slow down on the woodwork stuff but yup, more of this kind of thing would be fun 😄
Damn. This is a nod to safety glasses. They are incredibly informative.
I’ve had a cut off disc break on me before and it was my fault for twisting it slightly, but I’ve never had anything fly at my face from an angle grinder. A bench grinder vibrated apart my dressing tool and sent a hardened star shaped ring of steel into my safety glasses. That one almost penetrated; there are two distinct holes in the plastic lens of one eye spaced about an eighth inch apart
