Commonly used Drill bits, taps, and measurements

[cardcollector]

Hey all,

I decided that since I was compiling a list of common measurements I used, I thought it would make a great thread to have various drill bit used for switches, taps, etc...

So here is what I have so far. If you would like a measurement, post it up.

Drill bits, taps, and screws

- Use a 3/8” bit for hole
- Or use a 1/2” bit for countersink

For the Lighted 16mm anti-Vandal Switch
-To tap and thread; 15mm bit w/ M16-1 tap
-Use a 23/32 endmill to countersink the AV switch. Drill a 5/8" hole first.

For the Gaurded Switch
- If you want to use the retaining nut; 1/2" bit
- For a force fit; 7/16” bit. 11.5mm bits work well also.
