It carries the IC804 manufacturer grade with an AlTiN finish applied via PVD coating, including ISCAR's proprietary SumoTec surface treatment. The insert features an 80-degree diamond shape (Code C), a 0.40 mm corner radius, and the F3S chip breaker geometry. It is intended for right-hand cutting and belongs to the Isoturn series. This insert is primarily suited for machining ISO material group S workpieces, which includes superalloys and titanium alloys. Installation and tool setting are performed by machinists and CNC tooling technicians.\u003c\/p\u003e\u003cp\u003eThe 3321183 is used in precision turning applications where controlled chip breaking and wear resistance are required. The F3S chip breaker geometry is suited for finishing and semi-finishing passes at moderate depths of cut, with a maximum depth of cut of 1.50 mm (0.0590 inches). The Isoturn series is a general-purpose turning platform compatible with CNMG-style toolholders following ISO and ANSI insert seating standards. This insert is appropriate for production turning environments in aerospace, defense, and energy sectors where superalloy and titanium workpieces are common.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIC804 grade with AlTiN PVD coating and SumoTec proprietary surface treatment for extended tool life on difficult-to-machine materials\u003c\/li\u003e\n\u003cli\u003eF3S chip breaker geometry optimized for finishing and semi-finishing passes\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape (Code C) with 0.40 mm corner radius for versatile turning profiles\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut: 1.50 mm (0.0590 inches)\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting designation for standard toolholder orientation\u003c\/li\u003e\n\u003cli\u003eConforms to ISO 13399 tooling data standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNMG-style turning toolholders conforming to ISO insert seating standards.
