Milling matters

The M6330 grade has been developed to achieve longer cutting edge durability and reliability in a range of difficult-to-machine materials with and without coolant.  

Particularly suited to adverse cutting conditions, including interrupted cutting, the grade is now available with many of Dormer Pramet’s inserts, including the ADMX, HNGX, LNGX, LNMU, OEHT and various other ranges.

It is said to promote greater operational reliability and tool life and has a high resistance to heat-related cracks. This is due to improved abrasion resistance from a new substrate and PVD coating. 

Dormer Pramet has also added to its face milling range for stainless steel with new, larger diameter cutters and inserts for greater depths of cut and more powerful machines.

These latest tools include octagonal OEHT 09 inserts, suitable for unstable conditions and machining fragile components in stainless steels and soft steels up to depths of 5mm.  

The versatile tool can be used for both roughing and finishing operations, boosting tooling economy, and saving on machine time. 

A new range of round inserts, REHT 24, for face and copy milling and the XEHT 09 wiper inserts add to the options available. All can be clamped into the same milling cutter, further increasing versatility and cost efficiency. 

An overview of all the new products is available in the company's 2016.1 brochure.
