    摘要： The present invention relates to an internal groove insert. The internal groove insert comprises: a rectangular main body comprising 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 edge where the first and fourth lateral surfaces meet.

    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.

    摘要： The present invention discloses a cutting insert being capable of radiating effectively heat generated during the cutting machining process and having a structure by which a sufficient surface area is in contact with a tool holder and cutting fluid can be smoothly flowed. The cutting insert according to the present invention comprises an upper face and a lower face being opposite to each other, a plurality of side faces connecting the upper face and the lower face and a through hole passing through the upper face and the lower face, the upper face being divided into a periphery region disposed adjacently to cutting edges formed by the upper face and the side faces, and a central protruded region disposed between the through hole and the periphery region and surrounding the through hole, the central protruded region being placed higher than the edges. Here, the periphery region is formed along all the cutting edges and comprising an descent face inclined downward from the cutting edge to the central protruded region, a bottom face and an ascent face inclined upward from the bottom face to the central protruded region, and a plurality of grooves are formed on the central protruded region of the upper face, the groove being formed such that both ends of respective groove are directed to the adjacent cutting edges.
