    摘要： A parting blade includes an internal cooling agent supply and has two substantially plane-parallel lateral faces and a continuous transversal bore connected to a cooling agent channel that runs parallel to the lateral faces in the interior of the parting blade. In order to provide a parting blade that has no projection on one side, a stopper is provided having two substantially parallel end faces and a circumferential face that connects the end faces. The stopper can be inserted into the transversal bore of the parting blade, thereby sealing the transversal bore relative to at least one lateral face of the parting blade. The stopper terminates without protruding over the sealed lateral face, flush with the lateral face. The stopper has an opening on both the end face and the circumferential face. The openings are connected to one another in the interior of the stopper to connect the cooling agent channel to a cooling agent source.

    摘要： An indexable cutting insert has two cutting protrusions extending from opposite end surfaces towards a mid plane. Each cutting protrusion has a rear surface, an oppositely facing rake surface, a relief surface. A main cutting edge is formed at the intersection of the rake and relief surfaces, and extends between two main cutting edge ends. An edge projection is formed by a line connecting longitudinal projections of the main cutting edge ends of each main cutting edge. The edge projections of both of the main cutting edges form a non-zero first angle therebetween. The rake surfaces of the cutting protrusions are located on longitudinally opposite end surfaces of the cutting insert. Two clamping recesses and two abutment recesses serve as contact surfaces for clamping the cutting insert in an insert pocket of a cutting tool.

    摘要： A cutting insert comprising a rake face region located on an upper surface, a flank located on a front surface, and a cutting edge located at an intersection between the rake face region and the flank. At least three types of projections having different distances from the cutting edge are located on the rake face region. When these three types of projections are arranged in the order of their increasing distance from the cutting edge, namely, a first projection, a second projection and a third projection, the top of the second projection is located lower than an imaginary straight line connecting the top of the first projection and the top of the third projection in the side view.

    摘要： A round cutting insert includes a bottom surface, a clearance side surface and a top surface. The top surface includes a chip control feature in the form of a continuous, circumferential depression formed by a substantially planar bottom surface and a pair of upward sloping substantially planar side walls that form an angle with respect to the top surface. The chip control feature may also include a plurality of radially offset bumps located in the depression. The bumps may have the same size and shape, or may have a different size and shape. The top surface also includes an elevated island having one or more indexing marks for easy indexing of the cutting insert.

    摘要： A cutting insert and a cutting tool which can suppress lowering of blade-edge positional accuracy while holding by a holder having a small thickness is enabled are provided.
    The cutting insert includes a first end surface, a second end surface, and a peripheral side surface connected to the first end surface and the second end surface and having a rake face, a flank, and a cutting edge formed in a connection region between the rake face and the flank, and a through hole penetrating the first end surface and the second end surface is formed. It is the cutting insert including a first contact surface substantially perpendicular to a center axis direction of the through hole and capable of contacting the holder, a second contact surface substantially in parallel with the center axis direction of the through hole, substantially perpendicular to a plane including the first contact surface and capable of contacting the holder, and a third contact surface inclined with respect to the center axis direction of the through hole and capable of contacting the holder, and a cutting tool including the cutting insert as above.

    摘要： A cutting tool has a holder and an indexable cutting insert secured therein. The holder has a head and a shank extending therefrom along a holder axis, the head having spaced apart lower and upper clamping portions located on opposite sides of a first plane containing the holder axis. The lower clamping portion has spaced apart first and second lower clamping surfaces located on opposite sides of a second plane perpendicular to the first plane, and the upper clamping portion has an upper clamping surface intersected by the second plane. The cutting insert has a peripheral surface with a plurality of circumferentially spaced cutting portions, and the second plane intersects the plurality of cutting portions. The upper clamping surface makes contact with a first abutment portion of the peripheral surface, and a second abutment portion of the peripheral surface makes contact with the first and second lower clamping surfaces.
