ALO — Can withstand light interruptions. Alumina coating enables ALO higher cutting speeds. CG6 — High-speed, general-purpose grade for all kinds of steel and cast iron. CG6 CG55 — High edge strength and wear resistance. Reduces problems with built-up edge. Superior thermal deformation resistance and CG55 depth-of-cut notch resistance. C3 and C25 — Good wear resistance with some toughness. C3 and C25 C2 — Excellent abrasion-resistance for machining cast irons, austenitic stainless steels, non-ferrous metals, non-metals, C2 and most high-temperature alloys. CG5 — Best at low speeds. Will handle interruptions and high feed rates. CG5 CM1 — For heavy turning and heavily interrupted cuts.
