摘要： An internal groove insert includes a rectangular main body having a top surface, a lower surface, and first to fourth lateral surfaces; and first and second projections each projecting from the adjacent first and second lateral surfaces. The first projection has a first cutting edge at the side of the top surface of the main body, while the second projection has a second cutting edge at the side of the lower surface. The first and fourth lateral surfaces are inclined by an obtuse angle with respect to the top surface, while the second and third lateral surfaces are inclined by an acute angle with respect to the top surface. The central axis of the clamping hole is inclined to be parallel to the insert corner edge where the first and fourth lateral surfaces meet.

摘要： A clamp fastens a cutting insert to a tool holder. The clamp assembly includes a body portion provided with a screw hole, a forward protrusion formed at the front portion of the body and extending downward, a rear protrusion formed at the rear end portion of the body and extending downward, and a bridge connecting the forward protrusion and the central portion of the body. The clamp assembly also includes a pressing plate having upper and lower surfaces, a front nose portion, a rear end portion, and is provided with a keyhole shaped groove having an enlarged inner cavity open toward the rear end by a narrow neck extending thicknesswise. The forward protrusion is inserted into the enlarged inner cavity and the bridge is inserted into the narrow neck of the keyhole groove so that the pressing plate is coupled to the clamp.

摘要： The present invention relates to a cutting tool capable of both drilling and internal/external turning. The cutting tool comprises a generally triangular-shaped cutting insert and a tool holder. On each side, the triangular-shaped cutting insert forms a major cutting edge and a minor cutting edge, which is shorter than said major cutting edge. Two adjacent major cutting edges form an angle of 60° therebetween, while adjacent major and minor cutting edges intersecting at a corner of the triangular shape of the cutting insert form an angle of 80 to 89° therebetween. The cutting insert is mounted in a pocket so that one of the major cutting edges of the cutting insert is projected in an axially forward direction of the tool holder, while the minor cutting edge on the side adjacent to the projected major cutting edge is projected in a radially outward direction of the tool holder.
