Screwdriver Bit Set Wiha 41592

The Wiha 41592 screwdriver bit set contains five Torx T15 bits, each 25 mm long with a 1/4" (25.4 / 4 mm) hexagonal shank. Made in Germany, these bits are designed for durability and precision and are suitable for use with hand drivers, power tools and impact drivers when a T15 profile is required.

Advantages

Wiha's bit concept simplifies selection by making the screw shape the only deciding factor. The T15 bits feature a patented torsion zone that improves toughness for use with power and impact tools and provides up to 120× longer life compared to Wiha standard bits. A fluorescent coating and blue marking make the bits easier to locate, even in low light with a UV lamp, helping to reduce losses and replacement costs.

Suitable for

• Fastening and removing T15 Torx screws
• Use with manual screwdrivers and ratchets with 1/4" hex holder
• Use with power screwdrivers and impact drivers

Key specifications

How to use

Select a T15 bit from the set and insert the 1/4" hex shank into the screwdriver, bit holder or power/impact driver. Ensure the bit seats fully in the screw head before applying torque. When using power or impact drivers, start at low speed or torque settings to avoid cam‑out and increase as required.

Usage recommendations

Store bits in a designated holder to reduce loss. Use the fluorescent coating and a UV lamp to locate bits in low-light conditions. Replace bits only when worn to avoid damaging screw heads; the torsion zone increases service life but does not eliminate normal wear.
