Screwdriver Bit Set Wiha 41631

The Wiha 41631 screwdriver bit set contains five T15 Torx bits, each 50 mm long with a 1/4" (6.35 mm) shank, designed for accurate fastening tasks. The bits use Wiha's bit concept that selects bits by screw shape; they are suitable for both manual and powered use and include a fluorescent coating for easy identification in low light. The set is compact and intended for precision work where compatibility with common bit holders and impact drivers is required.

Advantages

Wiha bits are manufactured with a patented torsion zone that increases resistance to breakage under torque and makes them suitable for power tools and impact screwdrivers. The fluorescent coating improves visibility and reduces loss, while the standardized 1/4" shank ensures compatibility with most bit holders and quick-change chucks. The T15 size and 50 mm length suit many precision fastening applications.

How to use

Select the appropriate T15 bit from the set and insert the 1/4" shank into a compatible bit holder, screwdriver or quick-change chuck. Apply the bit to the Torx T15 screw head, maintain axial pressure, and drive the screw at moderate speed. For powered tools or impact drivers, allow the torsion zone to absorb torque peaks; avoid excessive side load to prolong bit life.

Recommendations

Use the bits with compatible 1/4" holders and avoid using damaged or worn bits. Store the bits in a dry place and use UV light for quick location when needed; replace bits that show rounding or excessive wear to prevent screw damage.
