Screwdriver Bit Set Wiha 41611

The Wiha 41611 screwdriver bit set contains five 3 mm hex (metric) bits with a 25 mm working length and a 1/4" (25.4 / 4 mm) hex shank. Manufactured in Germany, these bits are designed for compatibility with standard bit holders, screwdrivers and power tools. The set follows Wiha's bit concept where the screw shape determines bit choice; the specially optimised T-type bits feature a patented torsion zone that makes them suitable for power tools and impact drivers while delivering a significantly longer service life. A fluorescent coating and blue marking make the bits easier to find — even under UV light — reducing replacement costs and downtime.

Advantages

The set offers high durability and precision with bits made in Germany and a torsion zone that increases lifespan by up to 120 times compared to Wiha standard bits for the corresponding T-shaped screw applications. Colour marking and a fluorescent coating simplify identification and retrieval, including in low-light conditions when used with UV light. The 1/4" hex shank ensures broad compatibility with commonly used holders and drivers.

Suitable for

• Fastening and loosening T-shaped screws where a T-profile bit is required
• Use with manual screwdrivers and interchangeable bit holders with 1/4" hex sockets
• Use with power tools and impact drivers due to the torsion zone

How to use

Select the appropriate 3 mm hex bit for the screw head, insert the 1/4" shank into a compatible bit holder, screwdriver or power tool, and engage the screw. For power tool or impact driver applications, the torsion zone absorbs shock and reduces stress on the bit. After use, return bits to their storage to keep markings visible and prolong service life.

Usage recommendations

Use the bits with compatible 1/4" holders and follow tool manufacturer's torque settings when using power tools or impact drivers. Inspect bits regularly for wear and replace if deformation or excessive wear is visible to avoid damage to screw heads.
