    Best screwdriver bits ever!

    Posted by Matthew on Feb 10th 2019

    Excellent, as an aircraft mechanic I used to have to use EZ grip or something similar to increase grip for stuck screws. However with the diamond grit added I don't have to worry about it anymore. I used to use Snap on ACR bits but these are far superior at a better price. As a bonus the gold color and red sizing band make them easier to find in the event of a lost tool (FOD prevention). Overall I can't recommend highly enough.

    I can't tell the difference between these Wera bits and the straight BiTorsion without the diamond coating. In fact the only way I knew these were BiTorsion Diamond Coated was the BDC stamped on the base. The diamond coating isn't nearly and pronounced as in the photos.

    I own a very large number of Wera tools and this is the first time I've felt like maybe one of their products was a little over-hyped. Don't get me wrong, the bits still work great but after trying them side by side with uncoated Wera BiTorsion bits I can't tell any difference in performance.

    I think this is the first time I've ever rated a Wera tool less than 5 stars. I'm giving them 4 because they work great but no better than my other, less expensive, Wera bits.
