The demands placed on bits and bit holders are becoming increasingly intense, Impact drivers are conquering the power tools market. Work becomes faster and simpler.

Impact drivers are suitable for simple as well as more demanding jobs. Rotational blows tighten the screw more simply than a perpetual torque - somewhat similar to a nail which is driven into a wall with a hammer, the screw is tightened in the correct direction with permanent radial blows.

But Impact drivers also have disadvantages; extremely high contact pressure is required in order not to slip out of the screw. Bits and holder
are subject to rapid wear during screwdriving jobs. Permanently occurring torque peaks can exceed the physical limits of the tools currently available in the market.

Wera resists with its Impaktor system


Impaktor bits - depending upon the output, up to 5 times longer service life than with standard Torsion bits
Impaktor system bit and holder - Depending on the output, up to 10 times longer service life than with standard or Torsion bits.

Impaktor holder to cushion extreme impulse peaks, special torsion effect from the double-torsion spring, equipped with a ring magnet to easily hold longer and heavier screws, also ideal for abovehead work, particularly suitable for use with impact drivers, the magnet can be retracted and in this way disabled.
  • Suitable for bits with a 1/4" hexagon head drive
  • Enhances the productivity when screwdriving with power tools
  • Suitable for extra high torque e.g. from today's 18V impact screwdrivers

897/4 IMP Impaktor Stainless steel holder with retaining ring and magnet


The Impaktor stainless steel holder with a retaining ring and magnet is designed primarily for industrial screw assembly applications e.g. with screwdriving robots.
It focuses on the basic bit holding function and the cushioning of the extreme impulse eaks with its two different torsion zones.
  • n Suitable for bits with a 1/4" hexagon head drive
  • Enhances the productivity when screwdriving with power tools
  • Suitable for extra high torque e.g. from today's 18V impact screwdrivers

Impaktor Diamond bits25mm long


Minute diamond particles are applied to the tip of the bit. They literally šbite' themselves into the screw and in power tool applications reduce the particularly high cam-out effects.
  • 1/4" hexagon, suitable for DIN 3126-D 6.3, ISO 1173 bit holders
  • For use with impact screwdrivers
  • Particulary high strength
  • Reduce the danger of premature bit breakage
