Abstract
A metal cutting insert for use in turning or drilling operations and having a rake surface and a pair of relief flanks merging in a nose of radius r and defining with the rake surface a pair of cutting edges; each cutting edge having a first portion of length 1 tangential with the corner, the first portion enclosing an angle .epsilon. and a second subsequent portion defining between them an angle .beta.; a chip former groove being formed in the rake surface adjacent the cutting edges and the nose. The cutting edge is positive in the region of the nose and the first portions and the chip former groove adjacent thereto have a first portion which slopes towards a base of the insert, any chip deflecting portion thereof being sufficiently spaced from the cutting edge to allow for chips to have reached a desired minimal length prior to their deflection.
