CNMG and CNMA 80° rhombic inserts
CNMG is the most widely used turning insert: the 80° corner lets you turn and face with the same tool and offers 4 edges per insert. INNOT offers it with chipbreakers for finishing, semi-finishing and roughing of steels, stainless steels and superalloys, in cermet, in a cast iron version and as the flat CNMA without chipbreaker.
For heavy roughing there are CNMM-GX and CNMM-GZ, with a single-sided chipbreaker and a reinforced edge. Every product page shows the available sizes, nose radii and recommended grades.
