I'd like to cut two square holes into a plastic bumper, what are the best tools to use for this? I was going to masking tape out the profile, drill holes (being careful not to stray outside the boundary) and then neaten with a stanley. Any better ways to achieve this? I obviously want the tidiest holes possible and am thinking cutting discs will melt the plastic.
I would drill small holes in each corner then use a dremel on a slow speed and take your time. Ideally you need to finish it with a vent trim or something as it wont be perfect.

dremel all the way, wouldn't even consider another tool ....... and when you cut the square out, look inside and discover extra bits of plastic and metal bracing and stuff you didn't know was even there, swap the cutter for a penis shaped filer, whap the tool up to max speed, stick the dremel in there and wiggle it about until the noise stops ..... everything in that hole will have been filed down to nothing but the dust of melted plastic, metal swarf and bits of loom !
Annoyingly my Dremel packed up a little while ago, bugger! I might have to splash out on a new one as they are very handy.
The new quick change cutting discs they do are very good
If you don't want the expense of a Dremel, you could do it with a coping saw. They only cost a few quid and you just drill holes in each corner, thread the blade through one of the holes, attach to the coping saw frame and cut along the line.
You can tidy up the line with a rasp, file and/or sandpaper afterwards.
