Inserts for milling and copy milling, plus extended copy-milling cutter range from Dormer Pramet

Dormer Pramet SRC10 cutters for copy milling Inserts for milling and copy milling, plus extended copy-milling cutter range from Dormer Pramet
Dormer Pramet has launched a milling grade for general machining applications in a variety of engineering materials, particularly steels; a new range of copy-milling inserts; plus additional copy-milling cutters .

Suitable for finishing to roughing applications, even in unfavourable conditions, the M8330 provides a highly reliable and versatile option when machining either with or without coolant in steels and cast iron. It is also suitable for stainless steel, super alloys and hardened steels.

The M8330 replaces the existing 8230 grade and features a nano-layered PVD coating. This offers both improved productivity and tool life through increased resistance to thermal cracks, improved toughness and greater impact strength.

Added to more than 90 different types of existing Pramet milling inserts, the M8330 grade is also available in a completely new range of inserts for copy milling, also launched this November.

These RCMT10 inserts offer high metal removal rates, with up to 5 mm depth of cut and strong durability. Designed to allow a high feed per tooth, RCMT10 is available in three geometries. Geometry F is for stainless steels, superalloys and low carbon steels, geometry M for steels and stainless steels, while geometry R is for cast iron and hardened materials.

To support this addition, Dormer Pramet has expanded its current line of versatile SRC copy milling cutters with the SRC10 range of small diameter cutters. These are available in sizes from 25 – 66 mm and in a variety of types, including end-mills, modular and shell-mills.

Its double negative design provides a stable cutting action, even during roughing, and is suitable for a wide variety of operations including face-milling, helical interpolation, ramping, progressive plunging and high feed cutting.

All SRC10 cutters incorporate through coolant, a high number of teeth and feature a pocket design which gives maximum support to inserts with eight surface facets.
