Thanks everyone for the replies. Learned something new. I do have 2 tile saws, one with an angle grinder as the head, the other has a 10" blade. I never though of using those for cutting steel. Thank you again.Getting too hot without quenching will actually take the temper out and soften them. Quenching from the wrong temp could result in excess hardness.
An abrasive cutting wheel is your best bet though. Flood cooling it would be ideal. Got a tile saw handy?
I use a 10" sanding disk on my table saw for grinding; but I always vacuum out the sawdust to avoid 'dramatic learning moments.' :laugh:I cut some high speed steel for shaper knives using a 10 inch abrasive blade on my table saw. Worked great. But I should have cleaned out the sawdust below the saw first. It was a dramatic and long lasting learning moment.
