Bosch extra hard screwdriver bit set, 3 pieces, each with a 4 mm hex tip and 49 mm length. Bits have a 1/4" shank compatible with standard bit holders and quick-change chucks. The set is intended for durable fastening tasks and frequent use in household and professional applications; the tapered torsion zone absorbs torque peaks to handle demanding fastening jobs.

How to use

Select a 4 mm hex bit from the set and insert the 1/4" shank into a compatible bit holder, quick-change chuck, or screwdriver.

Replace the bit if wear or deformation is visible.

Recommendations

Use with the correct torque settings and avoid side forces to maximise bit life. Store bits in the original blister or a suitable holder to prevent damage and loss.
