Screwdriver Bit Set Wiha 41609

The Wiha 41609 screwdriver bit set contains five T30 Torx bits with a length of 25 mm and a 1/4" hex shank. Made in Germany, these bits are designed to fit T-shaped screws and to be used with hand tools as well as power tools and impact drivers thanks to an integrated torsion zone. The set features fluorescent blue marking for easy identification, even under UV light, and is engineered for long service life compared with standard bits.

Advantages

The Wiha T30 bits simplify selection by focusing on screw shape rather than tool type, reducing confusion when choosing bits. A patented torsion zone allows use with power and impact tools while increasing durability—Wiha states an up to 120× longer lifespan compared to their standard bits. Fluorescent blue coating improves visibility in low light and under UV, lowering loss rates and replacement costs.

Suitable for

• Driving T30 Torx screws in assembly and maintenance
• Use with manual screwdrivers having 1/4" hex bit holders
• Use with power tools and impact drivers for higher torque applications
• Work in dimly lit environments where UV identification helps

How to use

Select a T30 bit and insert it into a compatible 1/4" hex bit holder, screwdriver or power/impact driver. Engage the bit with the T-shaped screw head and apply steady axial pressure while turning. For impact applications, ensure the bit is fully seated and use moderate impact settings as required. After use, store bits in their holder to maintain the fluorescent coating and reduce loss.

Usage recommendations

Use the Wiha T30 bits with correctly sized 1/4" bit holders and matched Torx screws. Avoid excessive side loading to prolong bit life; inspect bits periodically for wear and replace when tip deformation is visible.
