Abstract:
A generally parallelogram-shaped cutting insert includes a top face; first and second main radial clearance faces, each intersecting the top face; first and second minor axial clearance faces each intersecting the top face and connecting the first and second main radial clearance faces; and a main cutting edge at the intersection of the top face and the first main radial clearance face. According to one non-limiting embodiment, the main cutting edge comprises a variable radial rake angle including a portion having a positive radial rake angle and a portion having a negative radial rake angle.

US Classification:
407113, 407115
Abstract:
An improved design of a cutting insert system includes a plurality of indexable peripheral milling cutting inserts adapted to be mounted on a peripheral milling tool holder. Each of the cutting inserts includes an insert width that is the same for each cutting insert. Each of the cutting inserts also includes a corner nose having a corner nose radius dimension that is different for each cutting insert, and an axial alignment clearance face that defines an equivalent face location and an equivalent clearance angle for each of the plurality of cutting inserts when the insert is detachably mounted on the tool holder.

International Classification:
B23B 5102
US Classification:
408227
Abstract:
A cutting tool or drill insert with chip control geometry comprising a body including a portion securable in a holder and a forward portion. The forward portion defining at least one cutting edge extending from the central axis of the body to an edge of the body. A chip groove is defined by the surface of the body adjacent to the cutting edge. The chip groove incorporates chip control geometry as spaced apart elongate projections.
