Chesterfield-based Dormer Pramet has launched a new range of solid carbide end mills for aluminium and non-ferrous materials. The additions to its Dormer S6 assortment includes three and four-flutes cutters, along with several smaller diameters to its existing two-flutes range.

The S6 assortment is particularly suited to precision and high-speed machining of aluminium and its alloys. All geometries provide high quality surface finish, making the range suitable for airframe assembly, automotive and die and mould applications — particularly for prototyping.

All three-flute designs (S650, S614 and S654) offer smooth cutting action and reduced stress on the spindle. A four-flute option (S662) includes various corner radius designs, reinforcing the end teeth for a stronger performance.

A differential pitch option is available on select cutters, reducing vibration, maximising productivity and tool life, while a positive rake angle enables a smooth cutting action, reducing the risk of work-hardening.

The S654 cutter features a neck recess to help avoid contact with the wall in shoulder operations and an NRA profile to break swarf into manageable smaller pieces, reducing spindle load and increasing metal removal rates.
