Hey folks just a quick question. I got a couple of old bandsaw blades last week and profiled a few blanks. My question is I am having a heck of a time drilling holes for the pins. I simply can't afford the carbide bits. I've broken at least 6 bits. I have tried slow with and without oil and still no dice. I thought about heating the metal and drilling while hot but don't feel comfortable doing so. What methods might I be able to try?
