Wera 05056172001 Screwdriver Bit

The Wera 05056172001 screwdriver bit is a 25 mm long metal bit with a 1/4" hex shank and a slotted tip treated with tiny diamond particles on the tip surface. The diamond particles improve grip in the screw head, reduce the required contact pressure and lower the risk of cam-out. The bit features a torsion zone that diverts kinetic energy under load peaks and a softer bi-torsion zone that prevents twisting of the bit tip under high loads, increasing the service life of the tool.

Advantages

The diamond-particle tip provides a more secure seating in slotted screws and reduces slipping. The integrated torsion and softer bi-torsion zones absorb shock and torque peaks, protecting the bit tip from deformation and extending overall durability. The standardized 1/4" hex shank fits holders to DIN ISO 1173-D 6.3, making the bit compatible with a wide range of bit holders and drivers.

Suitable for

• Precision slotted screw driving in metal and wood
• Assembly and maintenance tasks requiring controlled torque
• Use with powered drivers and manual screwdrivers that accept 1/4" hex bits

Key specifications

• Brand: Wera

How to use

Insert the 1/4" hex shank into a compatible bit holder or driver. Align the diamond-treated slotted tip with the screw slot and apply steady pressure while turning. For powered drivers, set an appropriate torque to avoid overloading. The torsion zones will absorb torque peaks during high-load operations; nevertheless, avoid using the bit as a lever or for prying.

Recommendations

Use the bit with holders conforming to DIN ISO 1173-D 6.3. Replace the bit when tip wear reduces engagement with the screw. For best results, match the bit size precisely to the screw slot and avoid excessive side loading to preserve the diamond-treated tip and torsion zones.
