To coincide with the forthcoming launch of their new rotary tooling catalogue in November, Dormer has strengthened its solid carbide milling programme with the introduction of several new ranges.

These include additions to existing cutter families as well as completely new ranges, such as, corner radius and super finishing cutters.

The most significant impact concerns Dormer's multi-application carbide milling range. Numerous unequal helix, corner radius and ripper variants greatly expand the options available to customers looking for multi-material versatility and consistent performance.

Designed primarily to improve production efficiency, the new cutters are recommended for use in a wide range of machines, applications and material types with the subsequent benefits of reduced inventory and time saved on tool changeover.

Also included in the multi-material machining programme are three chamfer cutters, available with 60?, 90? or 120? angles.

The company's ball nose cutter range is another bolstered by new additions. The introduction of several surface finishes and rake angles broadens the range of applications across the full spectrum of material types, extending to hardened steels (up to 63HRc).

A completely new addition to Dormer's carbide milling portfolio comes in the form of several four flute corner radius end mills. All feature unequal helix geometry and a variety of corner radii for smoother cutting action and increased corner life in a range of tough applications including fillet radii machining.

Two new cutter families target milling operations in a wide range of difficult to machine materials including stainless steels, titanium and nickel alloys. The first features unequal helix and unequal pitch geometry and supports operations from slotting to semi-finishing. "This," explains Dormer product manager Ricky Payling, "serves to harmonise the cutting action by reducing vibrations, benefitting tool life and enabling use of increased cutting data whilst also improving surface finish and reducing microchipping."

The second new range consists of multi-flute super-finishing cutters. Available with either Aluminium Titanium Nitride or Titanium Silicon Nitride coatings, all feature very high helix and low rake angles for consistent performance and tool life in target materials, including hardened steels, stainless steel and titanium and nickel alloys.

Finally, several new single and two flute cutters support milling operations in Aluminium and other non-ferrous materials. All feature highly polished surfaces to reduce friction between the surface of the tool and the workpiece, promoting fast, efficient, swarf evacuation and reduced machine downtime. A true diamond coated version is also available for highly abrasive materials - predominantly graphite.

All cutters are available in a variety of cut and overall lengths to promote use in a range of operations.
