摘要： A cutting insert has an upper surface having a long side, a short side, a lower surface, a lateral surface and a through hole. The lateral surface has a first lateral surface. The first lateral surface has a first plane that is overlapped with a central axis of the through hole in a front view and is parallel to the central axis, a second plane that is located closer to the short side than the first plane and is parallel to the central axis, a third plane that is located more away from the short side than the first plane and is parallel to the central axis, and a first inclined surface that is located between the second plane and the upper surface and comes closer to the central axis as coming closer to the long side. The first inclined surface is located away from the first plane.

摘要： Provided is a cutting insert which is resistant to breakage and can stably be restrained. A cutting insert configured as a vertically mounted insert has a first rake face adjacent to a first major cutting edge, a second rake face adjacent to a second major cutting edge, a restraint surface located further inward than the first and second rake faces to come into contact with a tool body when a second end surface is used, and a reinforcing portion projecting from the restraint surface. The reinforcing portion has a third projecting ridge provided to extend between the first and second rake faces and halve the restraint surface, a first projecting ridge connected to one end of the third projecting ridge to extend so as to cover at least a portion of a boundary between the first rake face and the restraint surface, and a second projecting ridge connected to another end of the third projecting ridge so as to cover at least a portion of a boundary between the second rake face and the restraint surface.

摘要： Provided is a cutting insert that can suppress damage of a corner cutting edge. The cutting insert has an approximately polygonal shape, and is constituted of a main cutting edge and a corner cutting edge connected to the main cutting edge. The cutting insert includes: a first side face portion that is connected to the main cutting edge, has a negative clearance angle, and is formed such that height thereof increases gradually in a direction of approaching the corner cutting edge; and a second side face portion that is connected to the corner cutting edge, has a negative clearance angle, and has height that is greater than the first side face portion.

摘要： A cutting tool includes a toolholder and a cutting insert. The toolholder includes a toolholder pocket having a pocket wall including a first anti-rotation engagement surface and a second anti-rotation engagement surface. The cutting insert is mounted in the toolholder pocket. The cutting insert includes: an upper surface, the upper surface having a plurality circular sinusoidal cutting edges; a lower surface opposite the upper surface; and an exterior sidewall between the upper surface and the lower surface. The first anti-rotation engagement surface and the second anti-rotation engagement surface of the pocket wall of the toolholder engage the exterior sidewall of the cutting insert to resist rotation of cutting insert.

摘要： An indexable cutting insert, arranged for being mounted in an insert seat of a tool body of a shoulder milling tool, includes a triangular top surface, a triangular bottom surface, and three circumferential surfaces extending between the top and bottom surface. On each side of the cutting insert an individual one of the three circumferential surfaces extends along an edge of the triangular top surface and along an edge of the triangular bottom surface. The cutting insert includes at each of the top and bottom surfaces three cutting corners, three main cutting edges and three minor cutting edges. Each cutting corner connects a main cutting edge and a minor cutting edge. Each of the cutting corners, each of the main cutting edges and each of the minor cutting edges are provided at an intersection between the top surface or the bottom surface and one of the circumferential surface.

摘要： Provided is a cutting insert, within which a burr being generated at an outer edge of a finished surface is inhibited and chipping of the cutting insert is inhibited even when the cutting insert is formed to have multiple corners superior in economical efficiency. The cutting insert has an upper surface, a lower surface on an opposite side to the upper surface, and a circumferential side surface connecting the upper surface and the lower surface to each other. A first ridgeline at which the upper surface and the circumferential side surface intersect each other includes major cutting edges and wiper cutting edges which are alternately disposed one by one, and corners each disposed between each of the major cutting edges and each of the wiper cutting edges. A distance between the corners that are adjacent to each other is equal to or less than 60% of a diameter of an inscribed circle of the first ridgeline. The corner that is positioned at one end of the wiper cutting edge is formed at a deburring cutting edge that intersects the wiper cutting edge at an angle smaller than an angle formed by the major cutting edge and the wiper cutting edge. The corner that is positioned at the other end of the wiper cutting edge is formed at a corner cutting edge having a curvature larger than that of the wiper cutting edge.

摘要： An insert may include a first surface, a second surface, a ridge line located at an intersection of the first surface and the second surface. The first surface may include a first corner, a first side and a second side. The ridge line may include a corner cutting edge located on the first corner, a first cutting edge located on the first side, and a second cutting edge located on the second side. The first surface may further include a first region located from the first cutting edge toward a midportion of the first surface, a second region located from the second cutting edge toward the midportion of the first surface, and a concave part located on at least one of the first region and the second region.
