Iscar OFMT 07T3-AETN IC910 Carbide Milling Insert (10pc)

The Iscar OFMT 07T3-AETN IC910 is a new, factory-sealed 10-piece box of octagonal (8-edge) double-sided positive carbide milling inserts designed for use in Iscar's Octomil and compatible face/shoulder milling cutters. IC910 is an Iscar CVD-coated cemented carbide grade featuring an Al₂O₃/TiCN multilayer CVD coating over a tough carbide substrate, targeting ISO K (cast iron) applications as confirmed on the package label, with a cutting speed range of Vc = 100–400 m/min (330–1320 SFM) and a feed per tooth of fz = 0.20–0.35 mm/t (0.0078–0.0137 IPT). The "07T3" size code indicates an insert inscribed circle of 7 mm with a thickness of approximately 3.97 mm, while the "AETN" chipbreaker designation denotes a sharp, positive rake geometry suitable for light-to-medium cutting depths of ap = 1.00–3.00 mm (0.039–0.118 in). These inserts deliver 8 usable cutting edges per insert, maximizing cost-per-edge economy in cast iron face milling, high-feed profiling, and shoulder milling operations on compatible Iscar Octomil toolholders.
