ABSTRACT:
A new cutting plate with a chip-breaker on at least one of the working faces, the plate being triangular or quadrilateral, with a preferably zero or positive back clearance and with a cutting angle which may generally be of any size but preferably positive. The plate is characterized in that the back clearance angle .delta. and cutting angle .eta. are obtained from cutting surfaces which are portions of conical surfaces with axes perpendicular to the plane Q.sub..gamma. containing the main cutting points, that the cutting edge comprises at least one arc of a curve, representing the intersection between at least one cone and the plane Q .alpha., and that the cutting surface adjoining a cutting point, comprising two consecutive surface elements joined along an arc of a curve in the plane bisecting the cutting point, causing discontinuity in the lines of level, is such that the cutting angle decreases as the plane No approaches the cutting point.
