In a tool holder and support combination wherein the support has a cylindrical recess opening to a first support surface, the recess having means forming a first shoulder facing away from said surface, and said tool holder has a cylindrical extension on an axis extending from a second support surface to lie in face-to-face contact with said first surface, that improvement which comprises a tool holder having:
- (a) an annular second shoulder formed on said extension to serve as a camming surface and spaced from said second surface to lie in proximity to said first shoulder,
- (b) first means movably supported on said cylindrical extension shaped to form an annular groove in conjunction with said second shoulder,
- (c) an expansive ring confined in said groove, and
- (d) second means to move said first means toward said extension to expand said ring radially beyond the cylindrical extension into annular contact with said first shoulder to retain said extension in said recess.
