    Best bit holder ever.

    Posted on Sep 19th 2019

    Got this for attaching to my 1/4 cordless ratchet and guns. Wow it’s fantastic. Great quality and has solid firm on bits. For being so small it’s quite the item. Always happy.

    Fantastic holding power

    Best adapter I've used even compared to the truck brands. Feels high quality but is prone to rust if left alone for a week in Houston.

    Wera 042750 1/4" Square to 1/4" Hex Adaptor

    This is a terrific adaptor. It holds tool bits with minimum play. The adaptor fits best on my relatively cheap craftsman 1/4 inch drive extensions. Very little play good feel for what is going on at the business end. Adding a handle to the extension and now I have T handle bit holder collection. The action of the bit holder is smooth and the bits are inserted and removed easily. Recommended

    Good addition to your Electronics Kit

    The bit holder is well-constructed and makes changing bits easy. Its a great addition to the tool kit. I'm using it for security fasteners, at the moment.

    Best of its kind

    Posted on Aug 31st 2015

    Wera makes the most refined and easiest to use of the several quick release adaptors of the same 1/4 to 1/4 design. I first bought a Tekton, which is functional but not pleasant to use due to an overly stiff spring. I've never been disappointed when I choose the WERA brand.

    Works bassackwards

    Posted on May 11th 2015

    Works well but I wish it were designed so you pulled the release collar back instead of having to push forward to insert a hex bit. This thing was engineered bassackwards so it only gets an average rating.
