Abstract: A cutter insert of the indexable type for a rotary cutter includes a body of a plate of a generally circular shape and having three notches of a V-shape formed in a circumferential face of the body in equally circumferentially spaced relation, each V-shaped notch being defined by a pair of first and second opposed walls. A front face of the body cooperates with the circumferential face, interrupted by the three V-shaped notches, to define three arcuate convex cutting edges each having a leading and a trialing end. A marginal portion of the front face disposed adjacent to and extending along each cutting edge serves as a rake surface for the cutting edge, the rake surface being recessed adjacent to the first wall of the V-shaped notch so as to slope toward a rear face of the body toward the first wall to provide a convex portion extending between the front face and the first wall. The first wall of each V-shaped notch, intersecting a respective one of the cutting edges at the leading edge thereof, is sloping toward the trailing end of the adjacent cutting edge at the second wall of the notch and is inclined with respect to a plane disposed perpendicular to the front face and passing through a center of a circle along which the one cutting edge extends and the leading end of the one cutting edge disposed at the first wall.

Abstract: A milling tool includes a reversible cutter insert with a central opening having two pairs of cutting surfaces and edges. A pair of planar locating shoulders are disposed on each side of the insert, and each shoulder extends between the insert side face and an adjacent one of the cutting surfaces. The plane of each locating shoulder is at an angle to and intersects the longitudinal axis of the insert central opening. A cutter holder has a slot receiving the cutter insert with a pair of planar locating surfaces oriented at the same angle as the insert locating shoulder plane. The holder locating surfaces are abutted with and contact the insert locating shoulders to support the insert and permit one of the pair of insert cutting surfaces and edges extending out of the slot to cut a workpiece.

Abstract: In this insert, in addition to the insert being formed so that the cutting edge is twisted at a helix angle within the range of 5° to 25° about the axis when the insert is attached to the insert mounting seat, the thickness of the insert body at the flank located on a straight line, which passes through the center of the rough hemisphere formed by the rotational locus of the cutting edge and forms an angle of inclination of 90° relative to the axis, is set to be within the range of 0.5 D to 0.9 D relative to the thickness D of the rough plate that composes the insert body. As a result, since a comparatively gentle but adequately large helix angle is imparted to the cutting edge, cutting resistance decreases. In addition, since the thickness of the insert body at the flank on the rear end side of the insert body is not excessively thin, the rigidity of the insert body is adequately secured.
