摘要： A cutting insert includes a first surface and a second surface each of which is polygonal and that face away from each other; a side surface that is continuous with the first surface and a side surface that is continuous with the second surface; a cutting edge formed along each of a ridge where the first surface and the side surface intersect and a ridge where the second surface and the side surface intersect; a bearing surface formed in each of a part the first surface and a part of the second surface adjacent to an insert center, the bearing surfaces disposed parallel to each other; and a recessed portion that separates the side surface that is continuous with the first surface from the side surface that is continuous with the second surface. The cutting edge includes three corner edges, a first cutting edge, and a second cutting edge, the first and second cutting edges being continuous with each other and located between each pair of the corner edges. A length of the first cutting edge is greater than that of the second cutting edge, an end portion of the first cutting edge adjacent to one of the corner edges is at a position higher than the bearing surface, and an end portion of the first cutting edge opposite to the end portion adjacent to the corner edge is at a position lower than the bearing surface. Each of the first surface, the second surface, and a cross section of the recessed portion has such a shape that outlines of the shape before and after rotation of the insert by 120° around the insert center are coincident with each other. The first surface and the second surface have the same shape, and the second cutting edge of the second surface is located at a corner at which the first cutting edge of the first surface is located.

摘要： A cutting insert has a trigonal shape. The cutting insert has a peripheral surface that extends between two opposing identical end surfaces. A median plane (M) bisects the cutting insert between the end surfaces. A through bore extends between the end surfaces. A cutting edge, formed at the intersection of each end surface with the peripheral surface, is divided into three identical cutting sections. Each cutting section is located between two vertexes of the trigonal shape. Each cutting section has a convex primary cutting edge and a concave secondary cutting edge that merge together. An insert tangential abutment surface is located between the cutting edge and the through bore. A primary relief surface forms an insert internal obtuse angle with a first reference plane (P1). A secondary relief surface forms an insert internal acute angle with a second reference plane (P2).

摘要： A drill for drilling in metal with improved performance in the smaller diameter range. The drill comprises a drill shaft, the front end of which is provided with radially outer and radially inner inserts, each insert having elongated rhomboidic shape, in which each of the short sides is broken at its middle to form a V-shape having an internal obtuse angle. The inserts are arranged such that the longitudinal axis of the radially outer insert is inclined at an angle from the longitudinal axis that is different from the angle of inclination between the longitudinal axis of the radially inner insert and the longitudinal axis of the drill.

摘要： A cutting insert includes a first surface and a second surface each of which is polygonal and that face away from each other; a side surface that is continuous with the first surface and a side surface that is continuous with the second surface; a cutting edge formed along each of a ridge where the first surface and the side surface intersect and a ridge where the second surface and the side surface intersect; a bearing surface formed in each of a part the first surface and a part of the second surface adjacent to an insert center, the bearing surfaces disposed parallel to each other; and a recessed portion that separates the side surface that is continuous with the first surface from the side surface that is continuous with the second surface. The cutting edge includes three corner edges, a first cutting edge, and a second cutting edge, the first and second cutting edges being continuous with each other and located between each pair of the corner edges. A length of the first cutting edge is greater than that of the second cutting edge, an end portion of the first cutting edge adjacent to one of the corner edges is at a position higher than the bearing surface, and an end portion of the first cutting edge opposite to the end portion adjacent to the corner edge is at a position lower than the bearing surface. Each of the first surface, the second surface, and a cross section of the recessed portion has such a shape that outlines of the shape before and after rotation of the insert by 120° around the insert center are coincident with each other. The first surface and the second surface have the same shape, and the second cutting edge of the second surface is located at a corner at which the first cutting edge of the first surface is located.
