Screwdriver Bit Wiha 41607 5 pc(s)

The Wiha 41607 set contains five 25 mm Torx T25 bits with a 1/4" hexagonal shank, designed for use with manual screwdrivers, bit holders and compatible power tool adapters. Made in Germany, these bits use Wiha's bit concept where the screw profile alone determines the correct bit. Each bit has a patented torsion zone allowing safe use with impact drivers and power tools while extending service life.

Advantages

The set reduces search and replacement time by using fluorescent blue marking that makes bits easier to locate, including under UV light. The torsion zone delivers higher wear resistance, providing up to 120× longer life compared to Wiha standard bits for T-shaped screws. The 1/4" hex shank ensures compatibility with common bit-holders and screwdrivers.

How to use

Select the T25 bit from the set and insert the 1/4" hex shank into a compatible screwdriver, bit holder or power-tool adapter. Apply steady axial pressure and use the appropriate torque setting on power tools or impact drivers. The torsion zone allows controlled deformation under overload to protect the tip and extend service life.

Recommendations

Use the bits with correct-size T25 fasteners and suitable toolholders. Inspect tips before use and replace if visibly worn. For best visibility when searching for bits in low light, use a UV light to take advantage of the fluorescent coating.
