Probably a Dumb Question
I am making some Oland tools. Got some 3/4" round bar, set screws, tap, drill bit, ferrules, cutter bits, etc. My problem is that I'm breaking drill bits. I've drilled my hole for the set screw and tapped it. Then, while working my way up the ladder to drill my hole for the cutter, I've broken 3 drill bits. There must be something I'm doing that is not right. Drill press is set as slow as it will go. I started with a tiny bit to get a pilot hole started. Every time I get into the intersection with the set screw hole I start hearing a clicking sound as if there were a chip trying to bind up. So, I retract the bit and clear the chips of metal. I reinsert the bit into the hole and at the same point I hear another click or two and then the bit breaks. What could I be doing wrong? Should I have drilled the deeper, larger cutter hole first and the set screw hole second? Help please! I'm about to pull what little hair I have left out.
Working flat so I can play round,
