Dimensions in mm. IC = insert diameter, S = thickness, D1 = hole, AN = clearance angle, APMX = maximum depth of cut (¼ of the diameter). Tolerance H: inserts ground on the diameter for high positioning repeatability. T = cutting edge with reinforcing land, E = honed cutting edge.

Technical data

Operation Milling – Copy milling and profiling: 3D surfaces, moulds, pockets, face milling and ramping
Shape Round, single-sided, 15° clearance, ground to tolerance H
ISO material P (steels), M (stainless steels), K (cast irons), S (superalloys and titanium), H (hardened steels)
Features The round cutting edge spreads the load over the whole circumference: it works with the same strength in face milling, copy milling and ramping. The reinforcing land (T) protects the edge in hardened steels up to 65 HRC and in interrupted cuts; grinding to tolerance H ensures positioning accuracy after every indexing.
Compatible cutters INNOT modular heads and shell mills for RDHX (see below), and copy milling cutters with a 15° round seat of the same diameter.

How many inserts per cutter diameter

Maximum number of inserts per cutter diameter (modular heads up to Ø42, shell mills from Ø42 to Ø80).

Modular heads for RDHX

Heads with M6–M16 threaded connection for carbide or steel extensions: ideal for deep moulds, where small diameters and high rigidity are needed.

Available INNOT grades

Grade ISO Coating Composition Application
IT6130 ★ P · K CVD TiN + MT-TiCN + Al₂O₃ Semi-finishing and roughing of steels and cast irons. High-strength composite coating that balances wear and toughness; post-coating treatment increases insert toughness.
IT7240 ★ M · S PVD AlCrN Milling of difficult materials: stainless steels, superalloys and titanium. High hot hardness, high toughness and resistance to fatigue fracture.
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.
IT7140 M · S PVD AlCrN Milling of stainless steels, titanium alloys and superalloys. Substrate with special micro-elements: excellent toughness and high-temperature performance.
IT5110 P · H PVD TiAlN + CrAlN + TiSiN Milling of hardened steels 45–55 HRC. Nano-composite coating on an ultra-fine grain substrate: smooth surface, low friction, high nano-hardness and excellent oxidation resistance.

Guide values with ap equal to 15–25% of the insert diameter. With lighter cuts the chip gets thinner: fz can be up to doubled (e.g. RDHX 10 on hardened steel: ap 0.5–1 mm, fz 0.10–0.24 mm/tooth). Hardened steels: machine dry with compressed air.
