Abstract

A cutting tool assembly comprising an elongated tool shank having, at a side adjacent a leading end thereof, a shank holding portion and an exchangeable adaptor having an insert retaining portion for retaining a replaceable cutting insert and an adaptor mounting portion releasably scoured to the shank holding portion by two clamping screws. The clamping screws are inserted into respective adaptor through bores formed in the adaptor mounting portion and threaded bores formed in the shank holding portion, the threaded bores being substantially aligned with the respective adaptor through bores. One of the adaptor mounting and shank holding portions is formed with a recess and the other one is formed with a protrusion mating with the recess and received therein, the bores passing through the recess and the protrusion and being oriented transversely to an axis of relative rotation of a workpiece with respect to the tool. The axes of the threaded bores are located substantially in a reference plane of the tool assembly which plane passes, during operation of the tool, through the axis of rotation. The axes of the through bores are slightly offset with respect to axes of the respective th…
