Brutal Angle Grinder Fight with Hydraulic Press

In this exciting Hydraulic Press Channel video, we put various grinding discs to the ultimate test! Watch as we attach an angle grinder to the hydraulic press piston and another to the press table, creating a high-pressure grinding disc showdown. Discover which grinding disc is the most durable and which one gets cut in the process. We'll compare different grinding disc materials and brands to find out which one performs the best under extreme conditions. Don't miss this epic face-off between the unstoppable force of the hydraulic press and the immovable object of the grinding discs. Tune in now to see which grinding disc reigns supreme!

It's still a grinder disc and therefore it can still kill everything

[@awldune]

I was actually shocked at how well the discs held together

[@avlehtine]

A thousand times this. I was expecting the 90 degree angle to just twist and snap the discs the moment they connected.

[@FixingWithFriends]

I was expecting more explosions, but I guess it goes to show how much better they last when held securely/consistently.

[@jarivuorinen3878]

@@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.

[@jarivuorinen3878]

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

[@sudinghosh9355]

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

I 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.

[@JohnSmythe-od4gk]

Important safety moment

[@christopherlewis1847]

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.

[@jo-han]

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.

[@BasedF-15Pilot]

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.

[@tigweldNY]

were you using a guard?

[@jttech44]

@@tigweldNY We both know the answer to that question is "no"

[@tigweldNY]

@@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.

[@tigweldNY]

@@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.

[@the_undead]

@@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

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 🤣🤣

[@ChickenDeranged]

the fear of two grinders coming together is very real! lol

[@jbnrusnya_should_be_punished]

It's interesting, but before doing any type of competition, you should do a baseline test with two identical grinders and discs, respectively, to ensure they will grind evenly and rule out the grinders' power affecting the results. I could be wrong, but I believe that even a difference in power of 100 watts can make one of 2 identical disks look better, simply due to the grinder's power.

[@superhawk20002]

And it seems like there is a bias towards the bottom grinder. I feel like it should be simple to see, but I cant wrap my thoughts around it. Repeating the tests with the same discs, just swapped grinder position would rules it out.
