The screwdriver bit is a replaceable screwdriving insert. Depending on the application, the shank of the bits can be clamped in a bit holder, a ratchet or a torque spanner. However, the bits are mostly fixed either directly or by means of a bit holder in the drill chuck of the tool. Since the bits have to fit the respective screw head exactly, there are also corresponding screwdriver bit types to suit the various screw types.
