A metal cutting tool assembly comprising a tool block; a substantially planar adaptor to be screw-clamped to the tool block; first and second insert clamping jaws formed integrally with the adaptor and defining between them an insert receiving slot for receiving a cutting insert; a relatively narrow neck portion formed integrally with the adaptor and serving to couple the first jaw with the remainder of the adaptor and screw coupling means for clamping the adaptor to the tool block; the screw coupling means including aligned screw receiving bores formed respectively in the adaptor and the block and so directed that screw insertion of a clamping screw into the aligned bores effectively clamps the adaptor against the tool block and, at the same time, exerts a resultant force on a first jaw so as to pivot it about the neck portion into effectively clamping the insert against the second jaw.
