      I had to make a bunch of holes (1/8" & 1/4") in 1.5mm thick FR-4 board
      (PC board material) and know twist drills aren't good for that. I tried
      Harbor Freight glass drills at a medium low RPM, no lube and found they
      cut a fairly clean hole (use a backer board) and I could drill stacks of
      5 boards at a time.
