Putting you in control of difficult materials

Dormer Pramet has launched several high-performance grades for milling hard materials and for precision thread turning.

The new milling grades - M4303 and M4310 - provide durability and reliability in semi-finishing and finishing applications.

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

Created within the company’s Pramet range, the M4303 replaces the previous 7205 grade and provides superior wear resistance. It has been developed for hardened steel above 55HRC and cast iron, but can also be used for machining steels and non-ferrous metals.

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

Meanwhile, Dormer Pramet has announced a high wear resistant grade for thread turning.

The new T8010 is ideal for continuous high precision thread turning of steels, stainless steel, cast iron and super alloys. It further extends the company’s Pramet assortment in this application area and supports the universal grade T8030.

Offering excellent wear resistance while ensuring operational reliability, the T8010 has enhanced plastic deformation resistance which provides a stable cutting edge and allows for increased speeds.

A gold finish on the insert provides a simple wear indicator, while a hard substrate and PVD coating has been optimized to deal with interior residual stress, helping to improve tool life.
