ABSTRACT:
An inserted cutting tool includes a tool body, a plurality of cutting inserts, a plurality of wedge members and a plurality of clamp screws. The body includes a plurality of pockets formed therein, and each pocket includes a recess for receiving the insert. Each wedge member has a hole formed therethrough and has a first abutment surface disposed in abutment with a front face of the insert and at least one second abutment surface disposed in abutment with the body. Each clamp screw passes through the hole of a respective one of the wedge members and threaded into the body so that the tightening of the clamp screw causes the wedge member to wedge the insert against the body. The first abutment surface of each wedge member is inclined with respect to an axis of the hole in such a manner that a wedge angle defined therebetween ranges from about 30.degree. to about 50.degree.. The wedge member is so disposed that the clamp screw extends radially inwardly of the body in a direction opposite to the direction of rotation of the body. Each clamp screw is displaced from a respective one of the inserts axially rearwardly of the body to thereby allow the insert and the clamp screw to be in an interference-free location.
