Grade TN6010TN6025TN7110THM TopGroove™ Grades and Grade Descriptions P Steel Coatings provide high-speed M Stainless Steel capability and are engineered for finishing to heavy roughing. K Cast Iron N Non-Ferrous S High-Temp Alloys H Hardened Materials wearresistance toughness Coating Grade Description 05 10 15 20 25 30 35 40 45 P An advanced PVD TiAlN coating over a very deformation-resistant unalloyed carbide M substrate. TN6010 is ideal for finishing to general machining of most workpiece K materials at higher speeds. Excellent for machining most steels, stainless steels, cast irons, non-ferrous materials, and super alloys under stable conditions. It also performs N well machining hardened and short chipping materials. S HC-S10 H P M An advanced PVD TiAlN-coated grade with a tough, ultra-fine-grain unalloyed substrate. For general-purpose machining of most steels, stainless steels, K high-temp alloys, titanium, irons, and non-ferrous materials. Speeds may vary N from low to medium and will handle interruptions and high feed rates. S HC-S25 H P Coated carbide. MTCVD/CVD — TiN-TiCN-Al2O3-TiN. Very wear resistant. Light and K medium machining. For steels and nodular cast iron. HC-P10 P M Uncoated carbide. Extraordinarily good balance of hardness, wear resistance, edge K stability, and toughness. Light and medium machining. For cast iron and all non- ferrous metals and non-metals. Useful in unfavourable conditions. N S HW-K15 H widia.com E47
