| TN7 | — High edge strength and wear-resistant cermet. | |
| ALO | — Can withstand light interruptions. Alumina coating enables | |
| higher cutting speeds. | ||
| CG6 | — High-speed, general-purpose grade for all kinds of steel and cast iron. | |
| CG55 — High edge strength and wear resistance. Reduces problems with | ||
| built-up edge. Superior thermal deformation resistance and | ||
| depth-of-cut notch resistance. | ||
| C3 and C25 — Good wear resistance with some toughness. | ||
| C2 | — Excellent abrasion-resistance for machining cast irons, | |
| austenitic stainless steels, non-ferrous metals, non-metals, | ||
| and most high-temperature alloys. | ||
| CG5 | — Best at low speeds. Will handle interruptions and high feed rates. |
CM1 — For heavy turning and heavily interrupted cuts.
