- Mar 3 9:04 AMI 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.
