Turning cutting insert NRM

with chipbreaker

We have launched new chip breakers for turning and bar peeling. The negative NRM turning chip breaker is for roughing and semi-roughing of stainless steel and low alloy steel. Launched under our Pramet brand, NRM is available for both double-sided and large single-sided inserts. It has been designed for continuous and mass levels of production, offering consistent performance and high feeds. However, the NRM has excellent chip-breaking properties and can also be used for roughing of stainless steel even at lower feeds, without the risk of work hardening. Its positive geometry with a wide T-land offers a broad depth of cut and promotes good chip evacuation in a wide number of applications. The chip breaker is available in grades T7325, T7335 and T9315. Meanwhile, we have developed a new chip breaker for bar peeling of stainless steel, steel and super alloys. Suitable for roughing to finishing operations, the MM chip breaker has been designed with a wide, strong T-land to offer increased stability of the cutting edge.
