how to drill through plastic

[JimmyDean]

Hello everyone! I was wondering what the best method was to drill through ABS plastic without cracking it, as I am building my supergun and don't want to crack my case. Thanks!

I would assume simply taking it slow is the best bet. But if you're drilling a very large hole in a smaller space, I'd start with a very small bit, and slowly work up from there.

drill a guide hole (or use an awl to get an indent) and then take it slow, at high rpm. the goal is to take off a ton of tiny pieces.

wow, you don't even need a pilot hole, most of the time even cheap ABS is full of led any way and just melts under the heat of the drill. so go slow or put the effort into a pilot first. my new best friend for many materials is the scrawl saw. dreamels tend to get messy when your burning lots of holes. get a few different sized cutting wheels for say dropping D-pads flush. and PRACTICE!!! make loads of things you aren't concerned with. well always do your best. but do some exploring, it saves these forums from getting heavy on single answer responses.

Also if you do like the dreamel say hello to hundred and thousand grit sand paper, it's always nice to have a smooth finish.

I have every drill bit known to man and have used them all on plastic and those Forstner Bits cut out PERFECT holes in the plastic every time. No accidental grabbing, no accidental slipping, no melting. just perfect holes.
