Available INNOT grades

Grade	ISO	Coating	Composition	Application
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.
IT7140 ★	M · S	PVD	AlCrN	Milling of stainless steels, titanium alloys and superalloys. Substrate with special micro-elements: excellent toughness and high-temperature performance.
IT7240 ★	M · S	PVD	AlCrN	Milling of difficult materials: stainless steels, superalloys and titanium. High hot hardness, high toughness and resistance to fatigue fracture.
IT5120	P · M · K	PVD	TiAlN + CrAlN + TiSiN	Universal grade for steels, stainless steels and cast irons, also ideal on materials of 35–50 HRC. Excellent wear resistance and toughness, high hot hardness.

★ Recommended grade. Other grades are available on request.

Cutting data and tips for use

Guide values on mild steel with IT5120/IT5130: Vc 180 m/min (140–220), ap 1.2 mm (SDKT09) / 1.4 mm (SDKT12), fz 0.8 (0.6–1.5) / 1.2 (0.8–2.0) mm/tooth. When ramping the maximum angle ranges from 3° (Ø25) to 0.4° (Ø125).
