    摘要： A cutting insert used in rotary cutting tools for performing turning spinning operations has an upper surface and an opposing base surface with a peripheral surface therebetween, the peripheral surface intersecting the upper surface to form a cutting edge. The cutting edge may be a continuous circular cutting edge. The upper surface has rotational asymmetry about an insert axis passing between the upper surface and the base surface, by virtue of having at least one spiral shaped protrusion with a chip deflection distance which continuously increases in a rotational direction about the insert axis for greater than 180°. The cutting insert is assembled to a cutting tool body having a shank portion and a cutting portion sharing a longitudinal axis, the insert axis being aligned with the longitudinal axis and the cutting insert secured in an insert receiving pocket of the cutting portion.

    摘要： A metal cutting insert comprises a top surface which is intersected by a frusto-conical edge surface to form therewith a round cutting edge. Five equidistantly spaced flat facets are formed in the edge surface. Upper ends of the facets are spaced below the cutting edge. A fixing screw secures the insert to the seat of a holder, such that two of the facets are pressed against respective flat contact areas formed on a locating surface of the holder. Each facet forms an acute angle relative to a central axis of the insert.

    摘要： A cutting tool for grooving and parting operations, comprising a tool holder provided at one of its side faces with a pocket in the shape of a polygon confined by a base support surface and at least a first and second side support surfaces projecting from the base support surface. A cutting insert is releasably securable in said pocket, said cutting insert being formed with a blade part and a base part with lateral surfaces protruding from the blade part. The base part is received in said pocket, such that a first and a second lateral surface of the base part contact the first side support surface and the second side support surface of the pocket, respectively. The first lateral surface is provided with a recess to the inside of the cutting insert, and the first side support surface is provided with a complementary projection to the inside of the cutting insert.
