C-Class

composition: A hard, low binder content, unalloyed WC/Co fine-grained grade.

application: Exceptional edge wear resistance combined with very high strength for machining titanium, cast irons, austenitic stainless steels, non-ferrous metals, nonmetals, and most high-temperature 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.

C3 - C4

composition: A hard, low binder content, unalloyed grade WC/Co fine-grained grade.

application: The K68 grade has excellent abrasion resistance for machining cast irons, austenitic stainless steels, non-ferrous metals, nonmetals and as an alternative to the K313 grade on most high-temperature alloys. Use as a general purpose grade for non-ferrous materials.

C3

composition: An advanced PVD TiAlN coating over a very deformation-resistant unalloyed carbide substrate. KC5010's new and improved coa­ting allows for speeds to be increased by 50 to 100%. application: The KC5010 grade is ideal for finishing to general machining of most workpiece 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 well machining hardened and short chipping materials.

^Ti AIM

C3, C4

n-1 TiAIN

composition: An advanced PVD TiAlN coated grade with a tough, ultra-fine grain unalloyed substrate.

application: 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 will handle interruptions and high feed rates.

C2, C6

^J TiBg

composition: A PVD TiB2 coating over a very deformation-resistant unalloyed substrate.

application: The KC5410 grade is designed for roughing, semifinishing and finishing of free machining (hypoeutectic <12.2% Si) aluminum, aluminum alloys and magnesium alloys. The TiB2 coating is harder than TiN and TiAlN coatings and has an extremely smooth surface, resulting in reduced surface friction, speedy chip flow and outstanding wear resistance. In addition, built-up edge is prevented because this coating has a very low affinity for aluminum. The substrate is unalloyed and fine grained and offers sharp edges, smooth surfaces, and excellent thermal deformation resistance and edge integrity. Inserts with a ground periphery are polished before coating and have a sharp edge. Molded inserts have a light hone.

C3 - C4

r-1 TiAIN

composition: An advanced PVD TiAlN coated fine-grained tungsten carbide grade.

application: Grade KC5510 is specifically engineered for the productive machining of high-temperature alloys. The fine-grained tungsten carbide 6% cobalt substrate has excellent toughness and deformation resistance while the advanced PVD coating allows for metal cutting speeds double those of conventional PVD-coated cutting tools.

C3 - C4

n-1 TiAIN

composition: Advanced PVD TiAlN coated fine-grained high cobalt carbide grade.

application: Grade KC5525 utilizes the same advanced PVD coating as grade KC5510 in conjunction with a fine-grained tungsten carbide 10% cobalt substrate. The higher cobalt provides for added security in interrupted cuts while the fine grained WC maintains hardness-resisting deformation at higher speeds. Designed for medium to heavy interruptions in high-temperature alloys.

C2 - C6

composition: An advanced PVD coating over a highly deformation-resistant carbide substrate.

application: KU10T is an ideal general machining grade designed for medium to finishing operations. KU10T is excellent when machining most steels, stainless steels, cast irons, non-ferrous materials, and superalloys under stable conditions. KU10T is also effective when machining hardened and short-chipping materials.
