Grade WK05CTWK20CTWS10PTWS25PTWU10HT WIDIA™ Victory™ • High-Performance Inserts Grades and Grade Descriptions Coatings provide high-speed P Steel capability and are engineered M Stainless Steel for finishing to heavy roughing. K Cast Iron N Non-Ferrous S High-Temp Alloys H Hardened Materials wear resistance toughness Coating Grade Description 05 10 15 20 25 30 35 40 45 P Coated carbide. MT-CVD/CVD — TiN-TiCN-Al2O3. Increased wear resistance for long tool life at high cutting speeds. Enhanced edge strength against K depth-of-cut notching in interrupted cuts. Maximum wear resistance for long tool life at high cutting speeds in finish to medium machining. HC-K05 P Coated carbide. MT-CVD/CVD — TiN-TiCN-Al2O3. First choice for a wide rangeof machining on all grey and ductile irons, light to heavy machining, smoothK or interrupted cuts, and wet or dry. HC-K20 P An advanced multilayer PVD coating over a very deformation-resistant unalloyed carbide substrate. The new and improved coating improves edge stability with M wide range speed and feed capabilities. WS10PT™ is ideal for finishing to general K machining of most workpiece materials at a wide range of speed and feed capabilities. Excellent for machining most steels, stainless steels, cast irons, N non-ferrous materials, and super alloys with improved edge toughness andhigher cutting speed and feed capabilities.S HC-S10 H P An advanced PVD grade with hard AlTiN coating and fine-grain unalloyed substrate. M The new and improved coating improves edge stability with wide range speed and feed capabilities. WS25PT™ is ideal for general machining of most steels, stainless K steels, high-temp alloys, titanium, irons, and non-ferrous materials at moderatespeeds and over a wide range of feeds, with improved edge toughness for interruptedN cut and high feed rates. S HC-S25 M An uncoated, hard, low-binder content, unalloyed WC/Co fine-grain grade. WU10HT™ offers exceptional edge wear and superior thermal deformation and depth-of-cut notch resistance. The grain structure is well controlled N for minimal pits and flaws, which contributes to long, reliable service. S C3-C4 widia.com B27
