Schroefbit Bosch schroefbit extra hard

The Bosch Screwdriver Bit Extra Hard is designed for durability and precise screwdriving. It has a Torx T10 tip, a 1/4" (6.35 mm) hexagonal shank and an overall length of 89 mm, supplied in a blister pack. The extra-hard material and tapered torsion zone handle high torque peaks and deliver consistent performance across a range of applications.

Advantages

The extra-hard construction increases wear resistance and extends service life. The tapered torsion zone absorbs sudden torque spikes to reduce breakage and improves bit stability during operation. The standardized 1/4" hex shank ensures compatibility with common bit holders and power drivers.

How to use

Insert the 1/4" hex shank into a compatible bit holder or screwdriver chuck until it locks. Match the Torx T10 tip to the screw recess, apply steady axial pressure and drive at an appropriate speed for the material. For high torque applications, ensure the torsion zone is aligned with the driver to allow controlled torsion absorption.

Recommendations

For prolonged service life, avoid excessive lateral forces and use the bit with drivers rated for the intended torque. Inspect the tip before use and replace the bit when signs of rounding or wear appear.
