Juego de puntas de destornillador Wera Bit-Check 12 BiTorsion 1 SB

The Wera Bit-Check 12 BiTorsion 1 SB is a compact set of 11 precision screwdriver bits designed for general workshop and professional use. The set contains Phillips, Pozidriv and Torx Plus tips, each 25 mm in length with a 1/4" hexagonal shank suitable for standard bit holders and drivers. BiTorsion geometry and hardened steel construction help absorb peak loads and reduce wear, providing reliable bit engagement and consistent torque transfer for a wide range of fastening tasks.

Advantages

The BiTorsion design reduces stress peaks during impact or high-torque applications, extending bit life and improving screw fit. Standard 1/4" hex shanks ensure compatibility with most bit holders, ratchets and cordless drivers. Precision tip machining delivers secure seating in fastener heads, minimising cam-out and reducing damage to screws. The compact arrangement of the set makes it easy to store and transport in a toolbox or service bag.

How to use

Select the appropriate tip from the set for the screw head profile. Insert the 1/4" hex shank into a compatible bit holder, screwdriver, or cordless driver until it seats securely. Apply steady axial pressure and rotate at an appropriate speed and torque for the screw material and size. For impact applications, the BiTorsion feature helps absorb shocks; still ensure the correct bit type and size to avoid fastener damage. After use, return bits to their holder to protect tips and maintain organisation.

Recommendations

Use the Wera Bit-Check 12 BiTorsion 1 SB with properly rated drivers and avoid excessive torque beyond the screw or driver capacity. Match tip type exactly to the fastener to prevent cam-out. Store bits dry and clean to prevent corrosion and inspect tips regularly for wear; replace worn bits to maintain safe, accurate fastening.
