Circular saw on a grinder? Also, test the blades spinning in the same plane. Opposite directions. And make them touch slowly. Don't have them at an angle like now.
I really appreciate what you say about the accumulation of grinding dust. It doesn't look dramatic in the moment like this example but it adds up fast. You're usually breathing in a lot more than you realize. Protect yourself. It's worth dealing with the discomfort/heat/fogging/whatever.
All dust is eventually like smoking, keep breathing it long enough for high enough concentration and you will develop lung cancer. Whether we live long enough to experience it is of course another question but research is quite clear that the variance in is quite big in how sensitive some people are for lung cancer. Some people are quite resistant and won't develop lung cancer even when smoking (smoke is also mostly dust) for 120 years, but other people can be so sensitive that daily vacuuming for 20 years is already a risk factor. The issue is, that you won't know beforehand how sensitive your lungs are.
@@avlehtine There's angular velocity and mass on the outer edge and it's quite substantial inertia at 10k+ rotations per minute. Grinder disks usually snap when working because it comes to a sudden stop, when the material you are cuttin pinches the blade. Most grinder discs can bend quite a bit, it prematurely uses up the disk but usually doesn't break it.
To answer to myself, most cutting DISCS break when they get pinched by the material you're cutting. It's the reason why circular saws have a blade to separate the material, to prevent kickback. For angle grinders similar pinching destroys the disk or stalls the grinder
I had a cut-off wheel explode on a disc grinder once, took me almost a year to get full functionality back in my thumb because a wheel shard hit it so hard I felt no pain, only pressure. That's when you know shit is bad, when a red waterfall pours from your hand but you feel nothing. Make sure your grinding/cutting discs are not expired, the glue that holds the abrasive material together degrades over time. I didn't know this.
@@jttech44 lol I was gonna give him a chance, but you are most likely correct. It gets in the way and whatnot, but yeah, I cringe when I see people using an abrasive cut-off disk or a stone grinding wheel with no guard. A lot of energy is going to be released when that thing binds the wrong way at 10,000rpm and frags. Google some pictures of the aftermath... it can be real ugly. Penetrating welding helmets and face shields and everything. Work safe, my friends.
@@jttech44 And there's no shame in being a little paranoid or let's say 'hypervigilant' about not getting hurt in the shop... a lot of injuries are life-changing. Think about it like you are potentially one of the first ones to die in a 'Final Destination' sequel and you'll be more likely to keep your appendages and functions, lol.
this channel was always chaotic fun, even after the novelty reached it's inevitable age of maturity, as all things must. but what you have done here is pure, pure poetry
@@johnturner4400 I miss Channel much safer usually means the chance of death is close to 50% instead of 80 or 90%. Whenever the diamond disc was brought out the chance of immediate catastrophic failure was high. Because when something like a diamond fails it fails very dramatically. And when you have something spinning at well over 1,000 RPM dramatic failures are not good for life and limb
I had a lot of old pipes and rebar to cut up and from what I read th-cam.com/users/postUgkxPDBfLu68o58Aw85O_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 always just SO AMAZED by the creativity of this channel. you have been going on for years and still keep innovating on what content you can create with the common thing being the hydrolic press. Amazing content.
Just when I think you guys have done the most terrifying thing ever you completely Amaze Me Again by doing something like this. I'm on the other side of the screen and I'm still ducking for cover.
When watching those 2 diamond blades going at it, i couldn't help but instinctively cover my eyes with my hands, expecting blade fragments to to be flying off. When I looked in the manual that came with my grinder, it didn't specifically say you shouldn't mount 2 of them in a press and push them into each other, so i guess it's perfectly safe 🤣🤣
The title of this video is one of those phrases I never would've thought I'd read, let alone had the possibilty existing with actual results. This channel is really great at that.
I thought for sure when this channel first blew up, that you would run outa ideas, but this is Amazing Idea, and you never cease to amaze me with your videos Thank you!
I remember the first time I used an Air Grinder for Autobody work, with 8" or 10" Disc, grinding out some fender rust, everything was going great, until I started on the inside of the wheel well and caught the edge of the disc and it EXPLODED! Luckily it all missed me, I was wearing eye protection and a dust mask, but what I really needed was Brown Stain Protection for my pants!
Its crazy how you do Seemingly stupid, fun and educational content in one, thats one of the reasons im staying on this channel, keep up the good work and try not to kill yourself with those experiments
That's exactly why I made my own using the big heavy metal gyro like wheel out of an VHS player and spun it up with a large DC motor to several K rpm, also because I couldn't afford toys when I was a kid so I got creative :D
Love these vids! I dont know why but its oddly satisfying for me to watch 2 high energy objects go against eachother or 2 really sharp objects cut eachother :D And ur commentary is funny af! Really hope to see more of this kinda stuff!
this! is why I subscribed! to the OG of the Hydraulic press channel!!! the only couple who can bring originality into the realm of pressing something unto something else!!!!! keeeep it going
You should do the same with Circular Saw Blades LOL. Yes...I'm crazy And stupid!!
This is definitely coming soon! maybe even next week :D
@@HydraulicPressChannel ohhh you guys are amazing!!! one of the best sience channels out there!

oh yeah. screw battlebots, i'm just going to watch angle grinders fight to the death from now on.
He can really grind away at his job.
and thumbnail is not clickbait 😀
Lol. I thought I missed the educational point of the video.
I was not ready for this violence 😳
It was terrifying to watch!
> I move away from the mic, not to breathe this grinding wheel shit.
@@theherk Yes, same here. Yuk.
… did you not read the title lol? He does say “brutal”.
The freaking chocolate rain guy is here!🥹
Holy shit, I fu*king love this channel. "2 grinders, 1 press. Shit happens." Lmao
Aaaah ptsd.
2 girls, 1 cup...
I love that you can hear a giggle after he says that
@@Orbuzzon hey! Shit also happens there!
@@Mr.Sparks.173 Ahahaha
"This time is going to be SLIGHTLY more safe." Now that doesn't sound like the Lauri we all know and love. 😂
Bruh , If that isn’t my life motto , I don’t. Know what is lol
It's still a grinder disc and therefore it can still kill everything

Important safety moment
It's the same with woodworking, especially when dealing with cocobolo. That sawdust can be deadly. It does not enter my shop. Always protect yourself.

I was actually shocked at how well the discs held together
A thousand times this. I was expecting the 90 degree angle to just twist and snap the discs the moment they connected.
I was expecting more explosions, but I guess it goes to show how much better they last when held securely/consistently.

"Don't breath this" - will it blend guy
iPhone Dust
Don't breathe a single breath.
Wow - that’s a throwback!
YES!! Will it blend.. that guy is a TH-cam icon..
He even had Ken Block on one of his videos
"Use the breathing thing when using the grinders. You don't want to breathe this shit."
Good professional advice.

Youre saving a lot of fingers by doing this so we dont have to let our intrusive thoughts win
and eyeballs
and garages
Never even comes once in my mind that I will watch an angle grinder fight each other.
this channel was always chaotic fun, even after the novelty reached it's inevitable age of maturity, as all things must. but what you have done here is pure, pure poetry
I don't think even 10 per cent of viewers realise that you have to clear the dust safely too.
Thanks Lauri for all the work done to entertain us 🎉
What do you mean?
Exactly the dust from those discs would absolutely shred your lungs
@@MonstertruckBadass
Think like glass dust you don't want to breathe that stuff in. Same with the angle grinder disc dust
Great reminder.
The dust is a side effect from grinding away at the job.
You are taking this to another and different levels every time, keep doing that !
0:18 Two Grinders One Press, i see what you did there :D
bahahahaha i thought the same
@@muenstercheese We all did.
The reason we love this channel: The epic tool battles that we all didn’t know we needed.
This is exactly the kind of stuff i have always thought in my mind but never had enough courage to try out xD
It was much safer than I thought :D
So does this mean we can try it at home?
"much safer" on this channel still isn't too close to "safe" for a normal person
@@Krecikdwamiljony yep don't try this at home :D

Finally some grind metal from Finland.
That is proper testing, I'm sure the grinder disk manufacturers are watching! 🙂
Yes, we are ;)
I didn't know I needed this until now!

This channel gets more and more dangerous and I love it.

I mean you have a whole series in just testing grinder discs vs each other
but also More safety yall shouldn't even be in that shop half the time I think
this has to be the sketchiest shit i've ever seen, i squinted the whole time and im no even in the room. i love it
4:13 That's one way to get a small cutoff wheel when you don't have a worn out one lying around..... Haha
I kind of wanted to take cover while watching this. 😄
Went smoother than I expected at least
Having a grinder cut into the gearbox of a running grinder would be interesting to watch.
This really grinds my gears 😂
I like the way you think
This is exactly how the manufacturers intended these discs to be used.
Dude! That's the most insane thing I've seen you do, yet! I love it!
You people are insane! This was so funny! And I will be sure to use the "breathing thing" whenever I use a grinder!
I like these because now I know exactly which discs to buy to grind down my other discs
Like Robot Wars but no let up. Good work!!! keep uploading please 👍🍺🇬🇧
I remember the first time I used an Air Grinder for Autobody work, with 8" or 10" Disc, grinding out some fender rust, everything was going great, until I started on the inside of the wheel well and caught the edge of the disc and it EXPLODED!

Not the video I expected that I actually want to see. Awesome
Anyone else find themselves moving to one side a bit whenever those discs started to touch? :p
"two grinders, one press, grinders are spinning, press goes down, shit happens" lol
Honestly the thumbnail sent chills down my back. Stopping all to watch this Face Off. Because these darn things can take your face off!
try adding some laterall projectile when the 2 disks are battling. some rubber band/spring loaded device for safety.
"2 grinders 1 press"
You are a genius Lauri hahaha
The 3rd match no survivals 😂😂😂
Bro you're going crazy with this
keep up the good content 😉
Its crazy how you do Seemingly stupid, fun and educational content in one, thats one of the reasons im staying on this channel, keep up the good work and try not to kill yourself with those experiments
Good to see you still hard at work! The world needs a mad scientist like you!
У мене навіть в кімнаті з'явився запах горілих дисків ) Дякую за відео!
I even smelled burnt disks in my room) Thanks for the video!
Such an inspiring channel - come up with simple but brilliant idea:
Put stuff in press, see what happens... 5.2 million subscribers.
the fear of two grinders coming together is very real! lol
its like watching two unstoppable objects against each other
Wow I have never really seen a channel that does this type of stuff just for fun and to see what happens, and its really interesting!
Laurie and Hanna y'all rock! Love the channel and content! Peace
I have never been more excited to see a video
this is the most educational channel on TH-cam
At 4:12 the way the discs just rapidly fart each other away is hilarious
"slightly more safe" LMFAO 😂😂😂😂😂😂😂😂😂😂
It is now plainly obvious why the Finland is the happiest country in the world for the sixth time. The fun police would be all over this in Australia.
This is exactly how I thought my bayblade would act like in real life back when I was 10, how disappointed was I....
That's exactly why I made my own using the big heavy metal gyro like wheel out of an VHS player and spun it up with a large DC motor to several K rpm, also because I couldn't afford toys when I was a kid so I got creative :D
"2 grinders 1 press" with a pause for laughter... awesome
These thoughts come to me in the middle of the night when I'm trying to sleep😂😂😂
This guy really grinds away at his job. Good work hydraulic press dude!
Very clever idea. Thank you 😃
Now know which disk to use in my shop if I need to grind or dull another disk...useful info. I do this all the time.
Even watching it seems dangerous😂
Seriously ! Ten points for creativity!
Amazing competition nobody never see on internet anything crazy like this 👌 good job I like this video and channel 💪
I LOVE ANGLE GRINDER FIGHTS!!!
I only had to watch 7 seconds to know this one deserved a like!
Actually the best grinder wheel review I've ever seen
This is the best use of angle grinders I've ever seen. Subing and my new fav channel. LOL This is what TH-cam is suppose to be.
I'm metal fabricatior and it's give me goosebumps watching this without safety goggles😁😁so cool😃
This is the kind of stuff that happens when you let your intrusive thoughts win LOL i love this
I commend your work in the field of unofficial power tool comparison! 👍🏾
Science simply does not get more science-y than this right here.
0:44 "...slightly more safe..." because flying cutter material is more safe when there's twice as much!
This is EXACTLY what I wanted!!!! Thank you!!!
I love all your post very entertaining and crazy, keep up the good work
Thumbnail still of the video does not disappoint. Great video.
Haven't even started watching and I had to push the like button.
I love this channel with a burning passion
Todo esto fue mas intenso que cualquier capitulo de Beyblade...
This channel hasn't disappointed me since i subscribed!
imagine u enter this workshop and hear cheering noises and see a crowd cheering and betting on the discs xD
Grinder go brrrrrr
Love these vids! I dont know why but its oddly satisfying for me to watch 2 high energy objects go against eachother or 2 really sharp objects cut eachother :D And ur commentary is funny af! Really hope to see more of this kinda stuff!
The fact that this occurs by accident, in my shop, makes me feel so creative.
How dangerous do you want the test to be?
Lauri: YESSSS!
This is what the internet is for! Thank you
Two grinders spinning at extreme speeds are clashing with hydraulic press' force. Sparks are flying.
5:59 'Something is going on'
I’m 1:57 in and you got some f*cked up sh*t going on. 😂 good shit! I love this channel. You’re crazy AF partner.
Very interesting video.. Thank You! Could not wait to see the results !
i Love the Grinder Battles :D
