American National Carbide has improved its grades designed for machining steels across the ISO P classification, from finishing to heavy roughing. All three negative-rake turning inserts in the P series have been reformulated to improve cutting characteristics and performance.

Grade AN3015 for finishing applications features a hard alloyed gradient substrate along with a multi-layered aluminum oxide CVD coating, enabling machining at higher speeds with resistance to flank wear and plastic deformation.

General-purpose grade AN3025 for machining alloy steels features a multi-layered oxide coating over a cobalt-enriched substrate for wear resistance and toughness at higher speeds.

Grade AN3035 for roughing is now more robust with a higher binder content and cobalt-enriched alloyed substrate. A multi-layered aluminum oxide coating provides toughness required for machining in unfavorable conditions, such as scale and interruptions, and with heavy depths of cut.
