Abstract: A cutting tool for chip removing including a cutting insert provided with a through hole, a J shaped locking pin actuated by a locking screw, and a tool holder having means to receive the cutting insert, the locking screw and the locking pin. The cutting insert is positioned in place by passing its hole over the clamping head of the locking pin and is securely locked into the tool holder's receiving pocket in both horizontally and vertically directions. For some embodiments the insert is clamped due to a simultaneous tilting and downward sliding movement of the locking pin while for other embodiments the insert is clamped due to both a horizontal and a vertical force which are components of a pulling force applied by the locking pin. A shim can be installed by passing its hole over the lower end of the locking pin and it is secured in place by the means of a collar that is provided by the locking pin.
