Unlike the normal high speed steel drill bits, even the titanium coated ones, these cobalt bits will go through lots of holes, even in heavier gage steel like z-channels and the like. The other bits go dull after just a few holes.

I followed all the instruction. Slow speed, cutting lubricant, etc. would not drill into a stainless steel screw head at all. Was hoping to use it with a screw extractor that required a bit of a hole in the head. No dice.
