Set di punte per cacciavite Wiha 41622

The Wiha 41622 screwdriver bit set contains five 25 mm square (T) bits with a 1/4" (6.35 mm) hex shank, manufactured in Germany. Wiha's bit concept simplifies selection by focusing on screw shape: these T-bits are designed for screws with a 90° angle between the thread and the screw head. A patented torsion zone makes the bits suitable for power tools and impact drivers while significantly increasing service life. A fluorescent coating with blue marking improves visibility and makes the bits easier to find, including under UV light.

Advantages

The set reduces replacement frequency through an optimised design that delivers up to 120× longer lifespan compared to Wiha standard bits. Enhanced visibility with blue fluorescent marking helps lower costs by reducing lost bits. The torsion zone permits safe use with power tools and impact screwdrivers while maintaining precision for square/T-shaped fasteners.

How to use

Select the T-bit that matches the screw head size, insert the 1/4" hex shank into a compatible screwdriver, bit holder or impact driver, and drive the screw with steady pressure. For use with power tools or impact drivers, ensure correct bit seating and moderate speed to maintain control. After use, store bits in their case or a designated holder to preserve the fluorescent coating and prevent loss.

Recommendations

Use the Wiha 41622 T-bits for applications requiring reliable engagement with square-head screws and where extended bit life and fast identification are priorities; inspect bits periodically for wear and replace when signs of deformation appear.
