    • The present invention relates to an apparatus for clamping a cutting insert to a tool holder. The present invention comprises a tool holder, comprising: a cutting insert pocket and a mounting bore; a clamp lever comprising a clamp portion and a lever portion placed in the mounting bore; and a fixing screw. The fixing screw is fastened through a hole which extends downwardly from a side wall of the tool holder to the mounting bore. One end of the fixing screw further comprises a pressure-applying surface substantially perpendicular to the rotational axis of the fixing screw, and the side surface of the lever portion of the clamp lever comprises an inclined surface which makes contact with the pressure-applying surface of the fixing screw. According to the clamping apparatus of the present invention, the cutting insert can be firmly clamped to the tool holder.

    • A hexahedral-shaped cutting insert is disclosed which has an upper surface, a lower surface, a plurality of side surfaces connecting the upper surface and the lower surface and a central hole passing through the upper and lower surfaces. The lower surface has a flat mounting surface, and the upper surface is curved concavely over the whole area thereof and provided with cutting edges along the borderline to the side surfaces, and corner cutting edge portions formed at borders of two adjacent cutting edges. The cutting edges are formed such that the height is largest at corner cutting edge portions and smallest in the middle portions. A land portion, a downward inclined surface, a bottom surface, and a seating surface portion are formed from the cutting edges inwards on the upper surface. A plurality of semispherical protrusions are formed on border portions between the downward inclined surface and the bottom surface, and at least one corner cutting edge portion has a corner bottom surface surrounded by an arc belt protrusion which connects two adjacent semispherical protrusions.

    • A clamping device for a cutting insert is provided to clamp the cutting insert having a central hole on a tool holder firmly by forming a projection on a pressing part. An insert clamp(20) fastens a cutting insert(10) having a central hole(12) to a tool holder(40). The insert clamp includes a front projection part(21), a central body part having a pressing part(22) and a screw hole(23) through which a clamping screw(30) passes, and a rear projection part(24) having a rear contact surface(25). The front projection part is formed on the front end of the insert clamp, spaced from the inner wall of the central hole, extended downward, and formed with a projection part(21b) having a convex surface tangentially contacting the inner wall of the central hole. The pressing part is formed on the lower surface of the central body part of the clamp, and formed with a projection part having a convex surface tangentially contacting the upper surface of the insert.
