摘要： A clamp mechanism capable of preventing a cutting blade tip from being shifted and spattered by a centrifugal force and preventing an extra displacement and a deformation from being produced on a rotary tool body; a rotary cutting tool for cutting by a plurality of throw-away tips (22) installed on the outer periphery of a cylindrical tool body (21), wherein the throw-away tips (22) are fixed to a cartridge (23) with mounting screws (24) to fix to a tool body (21), and the surface of the throw-away tip (22) in the area ranging from the use cutting blade of the tip to the other side thereof through the mounting screw (24) is pressed, for clamping, with a stop screw (26) inserted through an inclined screw hole (28) formed in the tool body (21).

摘要： A clamping mechanism that prevents the shift and scattering of the cutting inserts due to centrifugal force and that prevents the generation of unwanted distortion and strain in the rotary tool body. The rotary cutting tool of the present invention has a plurality of cutting inserts 22 along the periphery of a cylindrical tool body 21. The cutting inserts 22 are securely attached to cartridges 23 by using attaching screws 24. The cartridges 23 are then attached to the tool body. Each of the cutting inserts is clamped such that a set screw 26 screwed into the corresponding slanted threaded hole 28 formed in the tool body 21 presses the cutting insert 22 at its surface portion located on the other side of the attaching screw 24 with respect to the cutting edge of the cutting insert 22.
