Abstract: A rotary cutting tool includes a replaceable cutting tip having a cutting portion structured to perform cutting operations on a workpiece and a first threaded portion disposed generally opposite the cutting portion. The cutting tool further includes a generally cylindrical tool body disposed about a central longitudinal axis. The tool body has a first end portion adapted to be coupled to a machine tool and an opposite second end portion having a second threaded portion cooperatively engaged to the first threaded portion. The second threaded portion is moveable with respect to the tool body in a manner that selectively couples the cutting tip to the tool body.

Abstract: A toolholder has a pocket adapted to receive a double-sided on-edge cutting insert, wherein the corners of each side of the insert are radially shifted with respect to one another and has mounting pads preferably mounted about the sides of the cutting insert. The relief area for the corners of the insert is selectively fabricated to maximize the length of the support pads within the pocket of the toolholder.

Abstract: A cutter system that is designed to create a continuous cutting true helix while having cutting inserts that are indexable on at least two cutting edges by rotating the cutting insert. High positive radial and axial rakes enable free cutting machining with a fine finish and low horsepower consumption. The back face of the insert is substantially flat and is used for face contact on lockup with a mounting pocket on the cutter body when the insert screw is tightened. The mounting pocket is designed for ease of manufacture to limit tolerance buildup to ensure repeatable insert positioning and to maintain accuracy for a fine cutting finish. The insert screw hole is placed in the cross hole location for allowing an unobstructed cutting face and a larger diameter center core in the cutter body. The larger core creates maximum strength and allows longer cutting lengths. Prior to grinding, the insert blank can be used for multiple diameters of cutters. After grinding the insert blank, the inserts are made specific to the cutting diameter for which they were ground or a compromised grind may be employed for use with multiple cutting diameters.

Abstract: A cutting tool having an outer surface with a plurality of inserts connected to a distinct pocket extending generally radially on the outer surface. The cutting inserts are arranged in a helical array on the outer surface in a manner that at least one cutting edge of each cutting insert is spaced in an angular circumferential direction from the pocket of the next adjacent cutting insert. The spacing of the inserts is such that a distinct point on the each one of the one or more cutting edges define part of a layout line having a non-uniform slope.

Abstract: An indexable cutting insert includes a first component with an outer or top surface and side surfaces. A third component is mirror symmetric with respect to the first component about a vertical or y-axis of the cutting insert. A second component is disposed between the first and third components. Multiple cutting edges are defined at an intersection between the side surfaces and the top surface, wherein the cutting edges define a positive axial rake angle. In one embodiment, the first and third components are in the shape of a polygonal with a star appearance, and the second component is in the shape of a square. The first and third components are offset from one another by a first offset angle, while the second component is offset from the first and third components by a second offset angle to allow the cutting insert to be indexable.
