WNMG 80° trigon inserts

The WNMG combines the 80° corner of the CNMG with the 6 edges of a triangular insert: it turns and faces with the same tool and costs less per edge. It is widely used in series production on steels and stainless steels.

It is available with chipbreakers for finishing, semi-finishing and roughing, in cermet, for cast iron and ductile iron and as the flat WNMA version.
