Killer Drill Bit?
Who has a good drill bit to recommend for a tough steel drilling job? I have a broken starter bolt in my block that has been a thorn in my side. I finally came up with a way to center the whole for extraction and started drilling yesterday. Three different 1/8" bits and they all barely put a divit in the bolt. I hope I can just buy an individual bit for this first hole. I have left hand bits for going up in size
