The simplified analytical calculation and von Mises stress fields obtained by Finite Element Method are provided. The technical solution of clamping screw is based on the specialized screw head that is of hexagonal-conical shape. The higher axial force in screw arising from the tightening, higher contact pressure clamping the cutting tool insert. The frictional force between screw head and the insert surfaces presses the cutting tool insert into its seating when tightening and helps to get out the insert when un-tightening. The design of clamping specialized screws gives the possibility to use them in integrated cutting tools with two or more cutting tool inserts.
