Patent ID: 6945740

Claim:
A rotatable cutting tool for chip removing machining, comprising: a basic body defining a center axis of rotation and including: a front end surface, an envelope surface, chip channels disposed in the envelope surface, and cutting seats formed at a transition between the front end surface and the envelope surface and disposed adjacent respective chip channels; and cutting inserts detachable mounted in respective cutting seats, each insert having a square shape and including: first and second pairs of mutually parallel major cutting edges, four corners, and four wiper edges, each wiper edge situated between a major cutting edge and a respective corner, the wiper edges being shorter than the major cutting edges and inclined relative thereto wherein an imaginary extension line of the wiper edge forms a first acute angle with respective major cutting edge as the insert is viewed in a direction perpendicular to the top surface, the cutting seats arranged to orient the inserts wherein the axially forwardmost major cutting edge of each insert forms a second acute angle with the axis of rotation, the first angle being equal to the second angle, wherein an axially forwardmost wiper edge of each insert lies in a plane oriented perpendicular to the axis, and wherein a radially outermost wiper edge of each insert is oriented parallel to the axis.
