Wiha 41633 csavarhúzó-bitszett

The Wiha 41633 screwdriver bit set contains five T25 Torx bits, each 50 mm long with a 1/4" hexagonal shank. Made in Germany, these bits are designed for demanding fastening tasks and are suitable for use with hand drivers, power tools and impact screwdrivers where T25 screws are used. Wiha's bit concept simplifies selection by focusing on screw shape: the T-bit matches T-shaped screws with a 90° angle between thread and head for precise engagement.

Advantages

The bits feature a patented torsion zone that allows use with power tools and impact drivers while reducing breakage, delivering a lifespan up to 120 times longer than Wiha standard bits. A fluorescent blue coating makes individual bits easier to find, including under UV light, which reduces losses and replacement costs. The 1/4" hex shank ensures compatibility with common bit holders and quick-change chucks.

How to use

Insert a T25 bit into a compatible 1/4" bit holder or directly into the tool's chuck. Ensure the bit seats fully before applying torque. For power tools and impact drivers, engage at controlled speed and torque settings appropriate for the fastener and material to avoid cam-out. After use, store bits in their holder to protect the fluorescent coating and maintain easy identification.

Recommendations

Use the Wiha T25 bits for their intended Torx screws and inspect bits periodically for wear. The torsion zone is designed to absorb peak loads, but replacing heavily worn bits preserves screw heads and maintains fastening quality.
