Dormer Pramet has recently launched a new range of tangential face milling cutters and robust double-sided inserts for heavy roughing in the power and marine industries, which result in good impact strength and cost-efficient machining due to both high feed and cutting depth capabilities. The tangential inserts LNEX suit the S60LN15C cutter for face milling of cast iron and steel in heavy conditions.

The inserts were produced with grades M5326, M8326 and M8346, developed specially for heavy milling to offer additional durability, and come as M and KR chipbreakers. M suits positive geometry for standard workpieces and promotes low cutting forces, while KR suits negative geometry for hard workpieces and heavy cutting conditions.
