High Performance Carbide Endmills

Solid Carbide High Performance
Roughing & Hard Material Finishing End Mills

To complement Somta’s standard range of X.TREME coated solid carbide drills and finishing end mills (previously TiAlN coated as standard), we now introduce two new groupings of ultra high performance carbide end mills.

Roughers
A range of high performance roughing end mills for rapid stock removal, with new geometry designed for very low cutting forces. These new roughers are for general engineering applications such as side cutting, slotting and ramping – and can be used on machines with medium to low rigidity.

Hard Material Finishers
A range of high performance finishing end mills for operation on hard materials in the range 48 to 52 HRc (455-512HB). The finishers are designed for peripheral milling of contours and complex shapes, and are ideal for hardened mould and die steels up to 52HRc (512HB).

The main features of these new high performance end mill ranges include:
• Innovative new geometries designed in conjunction with our international development partners who have
   decades of design and development experience in the carbide tooling industry. The benefit is a range of
   state-of-the-art carbide cutting tools with superior performance.
• Chamfer and dubbing features to reinforce cutting tool corners for extended wear life and reduced cutting
   tool forces at higher speeds.
• Oerlikon Balzers X.TREME coatings which further improve operational performance and wear life.
• Sub-micron grain size of the European origin carbide substrate (0.2-0.4 µm for the hard material finishers,
   and 0.8 µm for the roughers), with 9% Cobalt content.
• Shank tolerances to h6.
• The high performance rougher ranges consist of regular length, coarse and fine pitch, knuckle and flat crest
   forms, most with X.TREME coating (only product group 03C is uncoated, suitable for aluminium machining
   applications).
• High performance finishers for hard steel applications include:
   Regular length square end (03G), regular length (03I) and long series (03J) ball nose variants, all with
   X.TREME coating.
• Designed to works standard over the 4mm to 20mm diameter range. 		TX7 ANCA

In combination, these features result in an extremely high performance carbide cutting tool range, which compete favourably with current global state-of-the-art solid carbide cutting tool designs. In some applications these new solid carbide end mills have outperformed competitive products by up to four times. High stock removal rates at high speeds and feeds, excellent finish quality and extended wear life are the major benefits of these new designs, in very hard work materials with complex applications.
