ABSTRACT:
A holder for tightly gripping the shank of an elongate cutting or like tool comprises a shank portion and a base portion with a cylindrical outer surface. The holder has a central bore for receiving the tool shank and transverse screws intersecting the bore for tightening against the tool shank. A ring encircles the cylindrical portion of the base member and under stresses caused by tightening the screws against the tool shank, the ring and base portion deform between conditions in which the ring is rotatable on the base portion and non-rotatable on the base portion. The rotatable or non-rotatable condition of the ring indicates the tightness of the screws.
