## Summary description

Wera Impaktor T40 bit, 1/4" drive, 25 mm length with diamond coating. Designed for Torx T40 fasteners, the Impaktor profile and coated tip provide improved grip and wear resistance under high torque. Suitable for impact drivers and hand tools with 1/4" hex holders; ideal for assembly, maintenance and demanding fastening tasks.

## Long description

Wera Impaktor T40 L.25mm 1/4" diamond coated bit is a single Torx T40 bit designed for use with 1/4" hex holders and impact drivers. With a 25 mm length and diamond-coated tip, the bit is built to reduce cam-out and to improve grip on Torx T40 fasteners. The Impaktor profile is engineered to withstand high torsional stress typical for assembly and maintenance tasks where repeated high-torque pulses are applied.
Advantages
The diamond coating on the working zone increases friction between the bit and the screw head, enhancing contact and reducing slippage. The Impaktor geometry provides greater resistance to wear and deformation under impact conditions compared to standard bits. The 1/4" hex shank ensures compatibility with common bit holders, quick-change chucks and many cordless impact drivers or hand-held tools. The 25 mm length balances access to shallow recessed screws while keeping control and stability during fastening.
Suitable for
 Driving Torx T40 fasteners in assembly and maintenance
 Use with 1/4" hex bit holders and quick-change chucks
 Impact driver applications where high torque pulses occur
 Tasks requiring improved bit-to-screw grip to prevent cam-out
Key specifications
 Bit type: Torx T40
 Length: 25 mm working length
 Drive: 1/4" hex shank
 Tip finish: diamond-coated working zone for increased friction
 Profile: Impaktor geometry for enhanced torsional resistance
 Intended use: compatible with impact drivers and hand tools
How to use
Insert the 1/4" hex shank into a compatible bit holder, quick-change chuck or the impact driver’s collet. Position the Torx T40 tip squarely into the screw head to maximize contact. Apply controlled pressure while operating the driver, allowing the Impaktor profile and diamond coating to maintain grip under torque pulses. Periodically inspect the tip for wear and replace the bit when fit or engagement deteriorates to avoid damage to screw heads.
Usage recommendations
Use with the correct Torx T40 fastener size and avoid excessive side load. For high-volume or continuous impact use, monitor bit condition regularly and replace when signs of rounding or coating degradation appear.
