    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.

    Good adaptor. Holds C63 bits well but a little loose for E63.

    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.

    Great Part, No Magnet

    Posted by Nuke on Feb 14th 2017

    While a magnet is not required since it grabs the bit's very securely, it would be nice to have a magnet to help the screws stick to the bit like other wera bit adaptors. Otherwise 5 stars.

    Need another

    Very clever solution for 1/4 bits. Right now it is being shared between my zyklop speed ratchet and my wera torque wrench. I am glad to be able to swap bits in order to save space in my bag.
