Available INNOT grades

Grade ISO Coating Composition Application
IT5210 ★ P · H PVD AlTiN + TiSiN Milling of hardened steels 50–65 HRC. Coating with high thermal stability and oxidation resistance: withstands the most severe cutting temperatures.
IT5220 P · M · K PVD AlTiN + TiSiN Universal grade for steels, stainless steels and cast irons up to 40–50 HRC. Double-layer coating: strength, toughness and protection against edge chipping.
IT5130 P · M PVD AlTiN High-efficiency milling of steels and stainless steels below 30 HRC. Specially formulated substrate that reduces the risk of chipping, with a latest-generation nano coating.

★ Recommended grade. Other grades are available on request.

Cutting data and tips for use

Preferably climb mill with the tool tilted by 10–15° to avoid cutting with the insert centre (zero speed).
