Grade WU10PTWU25PTWU10HTWP10CTWP25CT WMT™ Turning, Grooving, and Cut-Off Grades and Grade Descriptions P Steel Coatings provide high-speed M Stainless Steel capability and are engineered K Cast Iron for finishing to heavy roughing. 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 M An advanced PVD-TiAlN coating over a very deformation-resistant unalloyed carbide substrate. The WU10PT™ grade’s new and improved coating enables speeds to be increased K by 50–100%. The WU10PT grade is ideal for finishing to general machining of mostworkpiece materials at higher speeds. Excellent for machining most steels, stainless steels,N cast irons, non-ferrous materials, and super alloys under stable conditions. It also performs S well machining hardened and short chipping materials. H HC-P15 P M An advanced PVD-TiAlN-coated grade with a tough, ultra-fine-grain, unalloyed substrate. K For general-purpose machining of most steels, stainless steels, high-temperature alloys,titanium, irons, and non-ferrous materials. Speeds may vary from low to medium and willN handle interruptions and high feed rates. S H HC-P30 M A hard, low binder content, unalloyed WC/Co fine-grained uncoated grade. Exceptionaledge wear resistance combined with very high strength for machining titanium, cast irons,K austenitic stainless steels, non-ferrous metals, non-metals, and most high-temperature N alloys. Superior thermal deformation and depth of cut notch resistance. The grain structure is well controlled for minimal pits and flaws, which contributes to long, reliable service. S HW-K15 P A specially engineered, proprietary, cobalt-enriched carbide grade with thick K-MTCVD-TiCN coating layer, an Al2O3 layer of controlled grain size, and outer layers of TiCN and TiN for maximum wear resistance. An excellent finishing to medium machining grade for a variety of K workpiece materials including most steels, ferritic and martensitic stainless steels, and cast irons. The specially engineered cobalt-enriched substrate offers a balanced combination of deformation resistance and edge toughness, while the thick coating layers offer outstanding abrasion resistance and crater wear resistance for high-speed machining. The smooth coating provides good resistance to edge build-up and microchipping and produces HC-P10 excellent surface finishes. P A tough cobalt-enriched carbide grade with a newly designed multilayer K-MTCVD TiCN- Al2O3-TiCNTiN coating with superior interlayer adhesion. This is the industry’s bestgeneral-purpose turning grade for most steels and ferritic and martensitic stainless steels.K The substrate design, with cobalt-enrichment, ensures adequate deformation resistance along with excellent bulk toughness and insert edge strength. The coating layers offer good wear resistance over a wide range of machining conditions. The smoothness of the coating leads to reduced frictional heat, minimises microchipping, and improves workpiece surface finishes. HC-P25 widia.com E11
