Most twist bits are general purpose or designed more with metal drilling in mind. But you can buy a hi speed bit used especially for wood working. It has two cutters on the outside edge to give a clean cut. These work very well in plastic. Use low to medium speed and light pressure so as not to melt the plexy.

the suggestion approximately warmth is stable, yet enable's communicate related to the dimensions of the hollow. in spite of if it extremely is a hollow it extremely is countless inches extensive or wider, you do no longer drill it, you shrink it with a tumbler reducing device fastened on a swivel it extremely is caught to the middle of the place the hollow would be. What the warmth does is soften the glass, yet this get's troublesome. in case you had a propane torch with a needle skinny flame, you will have the skill to certainly soften interior the direction of the glass; the situation is that something of the glass contains warmth AWAY, so which you may on no account have the skill to soften the objective section. yet another technique i've got seen is to warmth up somewhat of metallic pipe it extremely is the width of the needed hollow. And as quickly as I say warmth up, I propose crimson warm. at the same time as your pipe section is getting warm, pre-warmth the section the place the hollow would be with a torch -yet do it progressively -its speedy ameliorations in temperature that shatter glass. Then place the nice and cozy end of the pipe the place the hollow could be, so the circle of warm metallic contacts the glass floor. depart it there for roughly 30 seconds, eliminate it, and then place ice interior the circle. The glass will fracture the place the metallic pipe substitute into and might then be punched out. it extremely is iffy, because of the fact sometimes a crack will only run interior the direction of the finished pane. Can the glass be bumped off? if so, mark the objective section, take it to a tumbler save and ask them to make your hollow for you. If no longer, it extremely is extremely helpful to to ask them to return to you and do the job. some vehicle glass places with cellular provider could be a stable guess, besides. there's a tumbler reducing drill bit, have self belief it or no longer, yet as others have pronounced, warm is stable once you employ it. stable success. extremely.

The only way I ever got a drill bit cleanly through a piece of plexigalss that thin was to set the drill to run in reverse and drill it that way. You need a new bit for this to work.

The best way is with a drill press (for steady, even pressure), a sharp (or new) drill bit, a piece of masking tape on top (drill thru it) and MOST DEFINITELY a piece of backing wood.
The pressure is the key.

Use a piece of masking tape over the spot you wish to drill--mark---predrill with a 1/16" bit--finish with end size bit--sand any burrs
