The deepened drive end of the KO-KEN Sleeve-Drive tools prevents the sometimes "wobbly" connection between pulse tool - extension - socket. An O-ring inside Sleeve-Drive optimizes the perfect fit of extension bars and sockets on the anvil to the effect, that the exactness of the required torque given by the pulse tool is generally improved. Further, the Sleeve-Drive avoids the direct transmission of vibrations on the pulse tool and finally on the operator.

The .ACK type is 1mm smaller than the average Sleeve Drive to fit on US models like Atlas Copco Pulse Tools.
