 iron screw "For demanding face-milling applications in steel, stainless steel, cast iron, ductile iron, and other materials, Dodeka inserts and cutters from Kennametal are engineered to deliver higher cutting speeds and feed rates along with extended tool life," said a spokesperson. "The results are improved cutting performance and productivity across demanding materials. "Compared to competitors' face-milling inserts, Dodeka inserts provide up to 30% more cutting performance at the same level of power consumption. At the same cutting conditions, Dodeka inserts supply up to 50% longer tool life. "With 12 cutting edges per insert, the unique Dodeka geometry generates low cutting forces, resulting in increased performance per edge. The inserts are also designed for ease of use, with a single screw for insert changing and indexing. "New HD roughing inserts in the Dodeka family exhibit excellent chip-forming and evacuation characteristics along with high accuracy - axial runout is less than 0.0004 inches and radial runout is no more than 0.002 inches. "Dodeka wiper inserts feature six cutting edges (three right hand and three left hand), and only a single wiper insert is needed to achieve a surface finish better than RA 1.5 at high cutting speeds. Inch and metric diameters are available across the entire Dodeka family." "Competitive pressures continue to grow for manufacturers around the world, and improving productivity remains critical for shops to stay in business," said Osny Fabricio, global product manager, indexable face milling for Kennametal. "The Dodeka family is a very cost-effective and user-friendly means to achieve better metalcutting performance in irons and steels."
