Wera Series 1 851/4 IMP DC Impaktor Power Bit, Phillips PH 2 Head x 1/4" Drive

Maximum utilisation of the material properties, a very special geometry - designed particularly to meet the extreme demands - as well as specific manufacturing process means that Wera Impaktor tools have superior 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.

Wera Bits are designed for the most demanding applications in trade and industry. They are designed to have the ability to transfer high torque loads, safe to use and extremely durable.

Features Impaktor design for Phillips screws, PH 2 x 50mm Overall Length x 1/4" drive

For hexagon bit holders and direct drives

Wera Bits for hard materials (e.g. metal sheets or structures) prevent premature breakages of the tip, created by the large amounts of peak torque generate to the screw and bit

    #2 Phillips Bit

    Strongest bit for impact use. Not the "God" bit but takes abuse in stride. If you are tired of constantly changing bits try this one.

    Tough but no Diamonds

    Posted by John O. on Jan 22nd 2018

    There is absolutely no diamond coating as far as I can tell, so the line about them aiding grip is total BS. Still, they wear longer than Dewalt impact bits and I haven't broken one yet.

    Great fit but short life

    Posted by D.O on Dec 30th 2017

    I was using milwaukee shockwave bits but wasn't satisfied with the fit, how much they deformed and how much wobble was in the shaft. These wera bits are made to tight tolerances and fit in stainless hardware very well. They spin true in the chuck, no wobble. My only gripe is that they explode a lot sooner than the milwaukees. I deal with a lot of stainless fasteners stuck in corroded aluminum and my M18 and M12 impacts will kill these bits after a couple hundred uses. The upside is that the tips keep their shape to the very end and don't destroy screws. I might buy more in the future but only after testing out some wiha bits too.
