On the magnetic Makita screw holder, what size bit should you use.
1 inches or 2. Or does it depend what type of screw length your using.
Some bits barely stick out of the holder, other stick out more

Doesn't the longer bit lock in?

Yes it locks okay. But on a shorter screw the sleeve fits better with the shorter bit

You may need to use both, sometimes you need reach, other times you may be in a tight spot?

Very good
