Chisel snapped
Paleo replied to Paleo's topic in Hot Cuts, Anvil devils, metal cutting on the anvil.
Thomas, Thanks for the info on tip quenching,no I did not move it up and down. The "tool steel" I used was from a demolition air hammer's 4 foot chisel cut down. Do you think I should use water,oil for quenching? Thanks Paleo -

I’m making a 14” chisel for stone quarry work made from 7/8 tool steel (according to spark test) with a 7” taper. The first one I made I cut the taper using a band saw and then sanded smooth. I then heated to cherry color quenched the tip and waited until blue moved down and a complete quench in water. The first time I used it an 1-1/2” of the tip snapped off. Where am I going wrong? Thanks
