Bosch PRO Impact Torsion Torx Screwdriver Bits T25 - T40

The Bosch PRO Impact Torsion Torx Screwdriver Bits are heavy-duty, impact-rated bits engineered for demanding screwdriving applications where durability and torque resistance are essential.

Manufactured from heat-treated modified steel, these bits deliver outstanding strength under high-torque conditions — making them well suited to installers, contractors, and tradespeople working with impact drivers and drill drivers on a daily basis. Bosch claim up to 50x greater robustness compared to their standard Extra Hard bits.

The extended torsion zone is a key design feature, absorbing torque stress at the tip of the bit rather than allowing it to build to a breaking point. This helps prolong bit life significantly during sustained heavy-duty use.

Colour-coded rings indicate the head type at a glance, while laser markings allow quick size identification — useful when working at pace on site. Available in T25, T30, and T40 Torx sizes, all at 55mm length with a standard 1/4" hex shank.
