Drill size for button & joy
ErikRuud:
My Milwaukee hole saw has a quick release arbor(the part in the middle with the pilot drill) to allow for interchangeable blades. I just pull the arbor out and pop out the plug with a screw driver.
Most other hole saws have some way to pull out the pilot bit. That usually makes removing the plug a lot easier.
shmokes:
It seems like Forstner bits aren't getting their fair share of discussion here. They're like a combination of the best of both worlds between a hole saw and a spade bit. They've been mentioned, but the debate seems to be focusted on spade bits v. hole saws.
my 2 cents
jon:
what should i use to drill button and joy holes on 1/8 inch plexi?
any tips on doing it also?
shmokes:
Use a 1 1/8" forstner bit. It drills the cleanest holes of the three bits and the lexan isn't as prone to melting as it is with the hole saw or spade bit. Spade bits are especially notorious for causing melting in lexan as I understand it. I've never actually drilled any lexan with a spade bit, though, so this is second-hand information. Don't pick to many nits over it, though. Remember that crappy button holes tend to look EXACTLY the same as nice clean button holes once the button is installed (the lip on the button will cover minor imperfections). If you're on a budget just go with the spade bit and you'll probably be perfectly happy with the results.

Shmokes is correct. Really whatever bit you use is cool. Your buttons will cover up any imperfections!
