Before you begin

Drill bit width and shank width

What size drill bit do I need?

The size of drill bit you need will depend on the size of the screw you want to insert.

A good rule of thumb is to select a drill bit that is slightly smaller than the width of the screw’s thread. This way, the drill bit will remove enough material to prevent splitting but will leave enough for the screw’s threads to bite into when its driven in.

Drill on top of screw You can check the sizes by holding the drill bit in front of the screw, and checking that the screw’s shank is no thicker.

Please note: Cordless screwdrivers all have hexagonal chucks, so ensure you select a drill bit with a hexagonal shank.
