Grade Description
Uncoated carbide. A very tough, ultra-fine grain unalloyed substrate. For
general-purpose machining of most steels, stainless steels, high-temperature alloys,
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
fail due to chipping or breaking.

HW-N15
Uncoated carbide. A hard, low binder content, unalloyed WC/Co fine-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.

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 finishing 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-finishing 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 finishing of grey cast irons and
medium-speed finishing of alloy steels that are in a hardness range of 35–50 HRC.
Can withstand light interruptions. Alumina coating enables higher cutting speeds.
