Dormer Pramet's latest milling grades - M4303 and M4310 - provide durability and reliability in semifinishing and finishing applications.

Each is designed for high-speed milling in the die and mold segment, offering consistent wear and longer tool life. An ultrathin PVD coating increases cutting edge toughness, while its substrate provides high hardness and cutting-edge strength, preventing fracture by chipping.

The M4303 replaces the previous 7205 grade and provides superior wear resistance. It has been developed for hardened steel above 55 HRC and cast iron, but can also be used for machining steels and nonferrous metals.

The M4310 takes over from the existing 7215 grade and offers an optimal balance of toughness and wear resistance in hardened steel and cast iron. It can also be used for machining stainless steel, steels and nonferrous metals.
