I've a need coming up to drill a dozen or so holes for screws in 2mm solid polycarbonate sheet - say 6mm holes for 4mm screws. But what drill bit should I use? Suggestions based on experience would be especially welcome as the internet has already given me a confusion of advice.
Some sites suggest special drill bits for plastics which I wouldn't mind buying if necessary, but they don't seem available locally/cheaply.
Some say that wood bits can be used - but don't say what kind of wood bit; and the Wiki[1] hints that my wood bits might not be the best thing.
OTOH some say high speed metal and multimaterial work. Or that high speed should be reground - which would be an adventure I'd rather avoid.
Oh, and I'd be doing this with handheld drills, not a press.
