Query: Skip this, get a chuck.

Forget about collets and nuts. Spend the extra few bucks and get a keyless chuck. You don't need to fumble around trying to find the right collet; the keyless chuck works just like a drill chuck - it opens / closes to the correct size without changing the collet. You won't believe the time and frustration you'll save.
