International cutting tool manufacturer Dormer Pramet is releasing a new strong HM geometry within its popular double-sided Pramet SNGX 11 high feed milling range. The HM geometry is ideally suited for use on hardened steels and cast irons. Source: Dormer Pramet

This addition extends the application range of the Pramet SSN11 cutter family, which already includes the versatile M geometry for steels and cast steels, and the MM for stainless steels, soft steels and superalloys.

The new HM geometry has a highly negative and narrow T-land, as well as a positive rake to reduce vibration and enable a smoother cutting action. Together, these improve the durability and process security, prolonging tool life in the relevant materials by up to 50%, compared to the existing assortment.
