What kind of bit should I use to drill a 1/2" hole into acrylic glass (plexiglass)? The local hardware store does not have a 1/2" hole saw - which was my first inclination. I am now considering these options in the following order:
- Spade bit
- Forstner bit
- 1/2" straight drill bit
- Step-up from small (3/16") to 1/2" straight bit
- Knock-out/Step-up bit
- 1/2" Diamond plug cutters (expensive)
I'm thinking the spade bit may work but will leave a rough surface (which I can sand) and will give me less control than a forstner bit. Starting with small straight bits and stepping-up to 1/2" seems safe but time consuming.
