P M Uncoated carbide. A very tough, ultra-fi ne grain unalloyed substrate. For general-purpose machining of most steels, stainless steels, high-temperature alloys, K

titanium, irons, and non-ferrous materials. Performs best at low speeds and will handle interruptions and high feed rates. Use when C2, C3, or C25 N fail due to chipping or breaking. S HW-S25

Uncoated carbide. A hard, low binder content, unalloyed WC/Co fi ne-grained grade. General-purpose grade for non-ferrous materials. Has excellent abrasion resistance for machining cast irons, austenitic stainless steels, non-ferrous metals, non-metals, and most high-temperature alloys.

HW-K15

HT-P15

HC-K15

Uncoated carbide. Has excellent abrasion resistance for machining cast irons, aluminium, and non-ferrous metals. Good wear resistance with some toughness. Harder than C2, resulting in greater edge wear resistance. Suitable for fi nishing operations.

A highly wear-resistant (TiC/TiN-based) cermet grade. High edge strength and wear-resistant cermet offers improved tool life over uncoated/coated carbides and resists material build-up on cutting edge. Finishing to semi-fi nishing of carbon, alloy, and stainless steels at medium to high speeds. Can also be used on non-ferrous materials.

Coated carbide. CVD — TiCN-TiC-Al2O3. A thin alumina coating over a hard, deformation-resistant substrate. High-speed fi nishing of grey cast irons and medium-speed fi nishing of alloy steels that are in a hardness range of 35–50 HRC. Can withstand light interruptions. Alumina coating enables higher cutting speeds.
