BillBoost37 is a glorious beacon of light

The thing I've found is ... a sharp bit starts to cut..then catches a little and creates a crack. That'* the reason for drilling in reverse..you are basically melting your way through.

so the idea is to really melt your way through rather then cut through... makes sense

When cutting..the edge catches and you get to start over again.

Been there..tried that too many times. Tried something else.

Did you try scoring the plastic? Take a metal straightedge and a utility knife. Score the line with the knife a few times, then give it a firm and quick snap with your hand.

Turns out that most RotoZip bits are 1/8" shank, same as those for Dremel. I use RotoZip bits and their knockoffs in my Dremel-type tool.

done it millions of times. The dremel/rotorzip are much better cuts.
