A:  Any drill bit should work on PVC pipes. I regularly drill 1/4" holes in PVC using a standard 1/4" drill bit.

A:  Yes these bits will cut plexiglass but you must first use masking tape to cover the area that you are drilling to prevent the plexiglass from heating up and also use a slow speed with light pressure.

A:  Don’t know. I only used mine on wood. Plexiglass I don’t think is that hard so it might work. Watch your speed so you don’t crack the plexiglass.
