Optimised endmill for highly alloyed steels

New grades of stainless steel and super alloys are constantly being developed for a range of industries where it is important that corrosion and contamination is minimised. However, as new materials with better characteristics are developed, the very properties that make them ideal for use in demanding applications also make them progressively more difficult to machine.

One company at the forefront of developing tools to keep pace with the advancement of materials technology is Sutton Tools. This Australian company—based in the northern Melbourne suburb of Thomastown—has long-standing partnerships with local universities and with the Defence Materials Technology Centre (DMTC) to develop and test combinations of base materials, coatings, cutting geometry and edge-preparation micro-geometry to optimise new tools to effectively and efficiently machine each new super alloy as it is adopted by the market.

The company’s latest product breakthrough is its VA-Harmony EndMill, which has been engineered specifically for milling stainless steels and super alloys—such as austenitic grades 304 and 316, duplex grades, as well as inconels 718 and 725.

Sutton Tools’ Harmony family is a range of endmills that is constantly being expanded to enable component producers supporting a broad spectrum of industries to successfully mill new materials as they are introduced. The Harmony line-up is primarily designed for use in CNC machining equipment, and the latest addition—the VA-Harmony EndMill—is aimed at those companies producing equipment for the oil & gas, aerospace, food & beverage, medical and marine industries.

Available in diameters from 6mm to 20mm, the VA-Harmony EndMill complements the existing range, furthering Sutton Tools’ aim to ensure its Harmony endmills include milling options that are optimised for any modern alloy material.
