ABSTRACT:
The present invention relates to a turning insert that comprises a generally rectangularly shaped body having a front end surface with a main cutting edge at the intersection between the front end surface and an upper land area. A chipforming area is provided in the forward portion of the upper surface and is shaped in the form of a number of distinctly provided recesses and ridges in order to promote improved chip control and to obtain narrower chips in grooving operations.
