What kinds? I need more specific info, like what would I buy if I went to home depot or a hardware store>

It's not like there's a recipe or anything. Just look at what you want to do, and get the tools that fit the job. Small hole = small drill bit, etc. Figure it out.

I want to cut big holes like 24mm and 30mm. That's hole saw tier size. So should I just buy a hole saw?

Yep. You probably can do it with a handrill if it's just thin plastic.

a hole saw should cut it just fine, just go slower so you don't melt it

Sharp drill bits(twist or Brad point should be fine, forstner too, skip spade) for smaller holes, up to maybe 1-1.5 inches. Decent hole saws past that, drilling slowly and making sure to evacuate chips frequently.

A rotary tool can do small cuts, Dremel makes those abrasive/fiberglass reinforced cutting wheels that are designed for plastic, they work pretty okay, and I think the miniature saw blades probably work well too. One of my favorites for thinner materials is a blade I made from some shim stock(a tin can lid works too). Cut a roundish piece out, around 0.5 to 1.5 inches, stab a small hole in it, mount it on a mandrel, and run it against some concrete or a rock or something until it's round, then touch up the edge a bit by just grinding it vaguely edge-shaped with the concrete/rock, the bottom of a ceramic mug, actual sharpening stuff, etc.

For larger cuts, just go slow, using whatever you normally would. Circular saw, reciprocating saw, miter saw, table saw, hand saw, etc. Higher tooth count and slower feed rate is key.

Plastic is weird, since it melts so easily, so a lot of the time you might need to clean up the edges a small bit.

For holes use pic related. For other shapes I would use a box cutter if the plastic is thin enough.

Are you the same guy who asked this 6 months ago but refused to buy a drill to do it?

We told you before that the soldering iron idea was retarded

Small holes - Step drill like >>1169989
Larger holes - Hole saw (wood backing material helps)
Other shapes - picrelated gets the job done, but for a lot of cutting, a jigsaw might be better

Styrofoam hot wire-cutters work for thin plastics too <2mm thickness too, but if it's just a circular hole, use a hole saw.
