Four high-performance milling insert coatings

Four high-performance PVD coated milling inserts deliver increased productivity through increases in both cutting speed and tool life. In steel, cast iron and stainless steel milling applications a 30 per cent increase in speed and a 25 per cent increase in tool life can be achieved reducing machining time and increasing They are designed to resist oxidation, have high hardness, increased density and optimised hot hardness. TN6510 (HC-K10) and TN6525 (HC-P25) offer a good balance of toughness, wear resistance and superior edge strength. TN6510 is designed for the milling of cast and nodular irons in application range K10; TN6525 has increased toughness for milling steel and high strength nodular cast iron. TN6520(HC-K20) with its increased toughness covers a wide operating range under both stable and unstable operating conditions when machining cast and nodular iron making it an ideal first choice for general application. Optimised for wear resistance TN6520 gives long reliable tool life even in the most demanding applications. TN6540 (HC-P40) completes the range, its combination of toughness, wear resistance and advanced PVD coating combine to give superior capability in the machining of steel, stainless materials, high temperature alloys and high strength nodular cast iron.
