Abstract
A cutting insert comprises an upper side or chip surface, a bottom surface and side faces extending between these two surfaces. At least one side face is provided with a first, possibly helically twisted relief surface and under this first relief surface, a secondary relief surface. Between these two relief surfaces a recess is provided. With this recess, all grinding in the immediate proximity of the cutting edge is avoided. Further, by providing the recess, it is also made possible to precisely position the insert in the milling cutter body, even when the first relief surface is helically twisted.
