ABSTRACT:
The invention is an improved clutching means for driving between axially aligned parts and is particularly adaptable in tapping attachments having free axial float. The clutch drive means is in the form of a sleeve having a ball race carrying driving balls interposed between axial splines on a driving part and on the driven splindle part in both direct and reverse drive.
A torque release clutch is provided. It acts on a drive member through which drive is transmitted in both direct and reverse drive so that it will release in the event of excessive torque in either direct or reverse drive.
