What tool(s) do you use for drilling button holes?

Grauwulf:
Those bits are only good for a wood CP.  If you have a metal cp, you either need a metal hole saw, similat to the wood one shown, or a step drill bit. Neither of those options are horribly cheap, so if you only have a couple of holes to do, I would call around to some of the local shett metal or machine shops and see if then can do the holes for you.

Thanks for the info - you answered my question before I asked. I have about 3 holes I need to drill into a metal CP. Looks like I'll need a new drill bit...

You can buy a bi-metal hole saw at the BORG or other big box lumber yards for less than $15. These will drill a hole in metal, wood, acrylic, etc. If you are building arcade games, this is a good staple for the tool crib!

for leaf or microswitch buttons?  1 1/8" is fine for microswitch but usually you need 1 3/16" for leaf.  A greenlee punch is the best way for metal.  You drill a pilot hole and then use the punch to cut the actual hole.  They can be found cheap on ebay but are expensive new.

For metal control panels I use a 1-1/8" knockout (a.k.a. chassis) punch from Greenlee.
