Reliable screwdriving with Wera

Practical benefits
  • Secure grip prevents slipping: Tiny diamond particles bite into the screw recess, ensuring you avoid frustrating cam-out and head damage.
  • Built for impact tools: The specialized Impaktor technology offers above-average service life, allowing you to handle demanding jobs with impact drivers.
  • Quick profile identification: Thanks to the clear color coding, you can instantly select the right TX 40 bit from your toolbox.

In a nutshell

The right choise for

With the Wera 867/1 imp DC sb Impaktor bit, you tackle demanding impact driver tasks with total confidence and control. Engineered to handle extreme peak torque, the Impaktor technology and specialized torsion zone absorb intense forces to prevent premature breakage and extend bit service life. The diamond-particle coating bites firmly into the screw recess, virtually eliminating cam-out, protecting fastener heads, and reducing required contact pressure. Featuring a standard 1/4" hexagon drive, a 25 mm length, and clear color coding for the tx 40 profile, this bit delivers the reliable performance you need for heavy-duty fastening jobs.

Product description

High quality bits for recessed TORX® screws. The Impaktor technology offers an above-average service life even under extreme circumstances. Enhanced friction resistance, thanks to the rough diamond-particle coating on the bit tip, prevents any slipping out of the screw head. Particularly suitable for use with customary impact drivers. 1/4" hexagon, suitable for holders as per DIN ISO 1173-D 6.3.

  • For recessed TORX® screws
  • Impaktor technology for above-average service life
  • Particularly suitable for use with customary impact drivers
  • Diamond coating for a secure fit in the screw, literally bites into the screwhead to prevent cam-out
  • 1/4" hexagon drive (Wera connecting series 1)

Application

  • TORX® socket screws

Drive

  • 1/4" hexagon, suitable for DIN ISO 1173-D 6.3 bit holders

Design

  • The Impaktor technology ensures an above-average service life even under extreme conditions thanks to a best-possible utilisation of the material properties and optimally designed geometry, particularly suitable for use with conventional impact drivers, the rough diamond coating reduces the danger of any slipping out of the screw head due to the enhanced frictional resistance. Take it easy tool finder: Output colour coding (green = TORX®) and large stamp to enable the desired bit to be easily located.

Features and benefits

  • Impaktor technology for an above-average service life even under extreme demands
  • For an above-average service life. Maximum utilisation of the material properties, a very special geometry - designed particularly to meet the extreme demands - as well a specific manufacturing process mean that Wera Impaktor tools have an above-average service life. Another product advantage is the coating of the Impaktor bits with minute diamond particles. These diamond particles reduce the cam-out effects - particularly high in power tool applications - which can lead to a slipping out of the screw head. The diamond particles literally bite themselves into the screw recess. This means that less contact pressure is required, something that greatly delays fatigue setting-in in power tool screwdriving jobs.
  • For use with impact screwdrivers. Improve productivity when screwdriving with power tools.
