Coffret d'embouts tournevis Wiha 41605

The Wiha 41605 screwdriver bit set contains five T15 Torx bits, each 25 mm long with a 1/4" hex shank. Made in Germany, these bits are designed for use with manual screwdrivers, power tools and impact drivers where T-shaped screws require a 90° angle between thread and head. Wiha's bit concept simplifies selection by focusing on screw shape; the T-bit in this set features a patented torsion zone that increases service life and allows safe use with powered drivers. A fluorescent blue coating makes the bits easy to locate, including under UV light.

Advantages

The set reduces tool replacement costs by offering a significantly longer lifespan compared to Wiha standard bits, due to the torsion zone optimised for T-shaped screws. The fluorescent marking improves visibility and recovery of dropped bits, even in low-light conditions when used with UV light. The 1/4" hex shank ensures compatibility with common bit holders and chucks.

Key specifications

How to use

Insert the 1/4" hex shank into a compatible bit holder or screwdriver. Align the T15 tip with the screw head and apply steady axial pressure while turning. For use with power tools or impact drivers, ensure correct seating of the bit before applying torque to reduce the risk of cam-out and to take advantage of the torsion zone that absorbs shocks.

Recommendations

Use the bits with appropriately sized T15 screws and check compatibility with your tool's chuck or adapter. When working in low light, use a UV light to locate fluorescent-marked bits. Replace bits that show visible wear or deformation to maintain screw quality and safety.
