Grade TN6010TN6025THM TopThread™ Grades and Grade Descriptions Coatings provide high-speed P Steel capability and are engineered M Stainless Steel for finishing to light roughing. K Cast Iron N Non-Ferrous • Reduce cycle times — high speed capability. S High-Temp Alloys • Longer tool life — new multilayer coating provides better wear resistance. 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 in machining hardened and short chipping materials. S HC-P10 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-P25 Uncoated carbide for light and medium machining. For cast iron, all non-ferrous K metals, and non-metals. Also capable of machining hardened materials at low cutting speeds.
