ABSTRACT:
A handle for a machinists vise configured to preset the maximum clamping force that can be applied to the vise jaws constructed such that, in tightening the vise, when a clamping force is applied by the operator to the handle equal to a preset value, a clutching mechanism in the handle will allow the handle to slip without further tightening of the vise. The mechanism includes a ratchet for positive engagement in loosening the vise and for providing a clicking sound that the clutch is slipping and thereby alert the operator that maximum clamping force is being applied.
