SNMG 90° square inserts for roughing

The SNMG has the strongest corner among turning inserts and 8 edges per insert: it is the most economical per edge for roughing and facing with 45° and 75° toolholders.

Besides chipbreakers for steel, stainless steel, superalloys and cast iron, INNOT offers SNMM-GX and SNMM-GZ for heavy roughing and the flat SNMA.
