    Wera 003529 Zyklop Bit Adaptor 1/4" Drive

    Posted by W on Feb 23rd 2024

    The best factor for my usage is that this bit holder does not have a magnet in it. Mechanical retention only. Bits and drives fit well, with just the right amount of wiggle room.

    Solid bit holder

    Super secure on both ends, only drawback is it’s not their Rapidaptor style so bit changes are slightly slower. Otherwise it’s great!

    This Wera Zyklop Bit Adaptor made my Zyklop 1/4-inch Drive Ratchet perfect. A must for anyone trying to downsize and get rid of dead weight.

    Socket use

    Posted by Paul Consani on Jun 21st 2020

    When traveling in my pelican case bits and sockets are used as much as possible to save tool case weight. This adapter makes all bits available to all drive ratchet handles and extenders. Great versatility. Good quality product.
