hey /diy/ how do I tap out about an inch hole in plastic? It's

>>1142177
drill a series of hole in the shape of a circle and the cut it out with a knife

I never thought about that

what about

1. drill a pilot hole

2, get a hole saw and run it on a very low speed just to scratch out an outline of my hole

3. heat up a paring knife with the stove and cut it out

would this be the best way?

Run the hole saw in reverse would work better desu...

why do you think heated blade is a good idea, it is not

just use a sharp knife and stop trying to smartass a new solution

Sauce on the car?

>>1142182
ok

>>1142181
yeah, so the teeth are just scratching it instead of cutting it (too much of a cracking risk)

thanks

depending how thick the plastic is, use a conduit hole punch

I believe you mean drill or bore, tapping typically refers to the act of carving threads into the already made hole.

Also use a dremel / $20 rotary tool off AliExpress with an off-centre collet and a locking pin that wears out after a month.

using a sheet metal knock-out punch is probably the option most likely to shatter the plastic into useless mulch.

Step drill bit. Center punch where you want the hole, pilot hole if your bit needs it.

Just heat a nail above the stove
