Abstract: A cutting insert includes a body having an upper face, a lower face, a plurality of planar flank faces joining the upper and lower faces, and a plurality of curved flank faces joining the plurality of flank faces. A T-land is formed at a downward sloping angle with respect to the upper face. A cutting edge is formed at an intersection of a respective flank face and the T-land. A curved cutting edge is formed at an intersection of a respective curved flank face and the T-land. A micro-channel is formed in one of the flank faces, the curved flank faces and the T-land and proximate one of the cutting edge and the curved cutting edge.

Abstract: A cutting insert (100,100′) includes a body (102) having a top face (104), a bottom face (106) opposite the top face (104), and at least one flank face (108, 110, 112, 114). A coolant inlet aperture (126), a coolant outlet aperture (132, 134), and an internal coolant passage (128, 130) in fluid communication with the coolant inlet aperture (126) and the coolant outlet aperture (132, 134) are formed using electro-magnetic radiation. The coolant inlet aperture (126) can be formed in the top face (104), the bottom face (106) and/or the flank face (108, 110, 112, 114), and the coolant outlet aperture (132, 134) can be formed in any different face (104, 106, 108, 110, 112, 114). A method of forming the internal coolant passages (128, 130) is described.

Abstract: The invention relates to a method for producing a blank, in particular a blank for the production of a cutting tool, wherein a green body extending in the direction of the extrusion axis is produced from extrusion material by means of an extruder which has an extrusion channel extending along an extrusion axis; wherein the extrusion channel together with a movable mold element forms a die of the extruder; and wherein the mold element is moved relative to the extrusion channel and within said extrusion channel during the extrusion of the green body, whereby the shaping geometry of the die is changed so that the completely extruded green body hereby has a first functional segment and a second functional segment adjacent thereto in the direction of the extrusion axis (4); wherein the two functional segments differ with regard to their geometries impressed by the die.
