We finally got hardened steel tools for our big 300 ton hydraulic press — and now it’s time to find out if they are actually strong enough. First we try something people have asked us to do for years: crush coins properly with 300 tons of force. Normal steel tools get dented by coins, so the result is never perfectly flat. These new vacuum-hardened steel test pieces should be much harder… but 300 tons on a tiny area is absolutely brutal. After the coins, things get more dangerous. We test hardened steel pieces, ball bearings, and different setups to see if anything finally explodes like a hand grenade — or if even “super hard” steel just bends, dents, and survives in a really surprising way. Can hardened steel survive our 300 ton press? Let’s find out. Thanks for watching, and have a nice day!
