How do you guys go about putting holes in cutting edges? Always wondered how other people do this, never did ask. I have had no luck drilling , annular cutters don't even scratch them. So out comes the torch, which is a pain. Never had much problem blowing holes through thick mild steel but I think it's where the cutting edges work harden is why it's so tough to torch or drill. Have not tried either on new edges as they usually have holes punched in them already. Just wondered if there was a better way than torching, or not. Thanks!
