Manufactured to ANSI code SPMT432-WL 4040 and ISO code SPMT 12 04 08-WL 4040, this insert features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN for extended tool life and heat resistance. The square SPMT-style geometry includes a positive rake angle, an 11-degree relief angle, and a 0.80 mm (0.0315 inch) corner radius with a WL chip breaker. It carries four cutting edges and is single-sided with neutral hand orientation. Installation is by screw clamping. This insert is specified and installed by machinists and CNC tool setters working in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for milling steel, stainless steel, and cast iron workpieces, covering ISO material application codes P, M, and K. It fits Sandvik Coromant cutter series R215.64 and RA215.64. Typical applications include shoulder milling, face milling, and light ramping passes where controlled chip formation and consistent surface finish are required across medium-to-high volume production runs or maintenance machining work. The WL chip breaker geometry supports stable cutting in these material groups across a range of cutting parameters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with CVD multilayer TiCN, Al2O3, and TiN coating for wear and thermal resistance\u003c\/li\u003e\n  \u003cli\u003eSquare SPMT insert shape with 4 usable cutting edges, single-sided, neutral hand\u003c\/li\u003e\n  \u003cli\u003e0.80 mm corner radius with WL chip breaker for controlled chip evacuation in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle and 11-degree relief angle reduce cutting forces on the workpiece and toolholder\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.4685 inches; inscribed circle of 0.5 inches\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO insert standards; compatible with R215.64 and RA215.64 cutter bodies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in Sandvik Coromant cutter series R215.64 and RA215.64.
