It features a TiN and TiCN PVD coating applied over a carbide substrate rated at material grade P40, making it suited for moderate to demanding turning operations. The insert has an 80-degree trigon shape with a 5-degree relief angle and a right-hand cutting orientation. Corner radius measures 0.008 inches, and the inscribed circle diameter is 5\/32 inch (0.156 inches). Maximum depth of cut reaches 2.01 mm (0.079 inches). This insert is part of the Isoturn series and is installed by machinists and CNC turning specialists in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is designed for turning stainless steel and steel workpieces, covering ISO material codes M and P. The Isoturn series targets external and internal turning applications where consistent chip control and tool life are required. The T-style chipbreaker geometry manages chip flow during continuous and light interrupted cuts. Typical use cases include shaft turning, facing, and profiling operations on CNC lathes and turning centers. The screw-holding method provides secure clamping in compatible toolholders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with PVD-applied TiN and TiCN coating for wear resistance on steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003e80-degree trigon (WBMT) insert shape with 5-degree relief angle for positive cutting action\u003c\/li\u003e\n  \u003cli\u003e0.008-inch corner radius for a balance between edge strength and surface finish\u003c\/li\u003e\n  \u003cli\u003eT-style chipbreaker geometry for controlled chip evacuation during turning\u003c\/li\u003e\n  \u003cli\u003eScrew-holding method compatible with standard Isoturn toolholder seats\u003c\/li\u003e\n  \u003cli\u003eConforms to ISO 13399 tooling data standards for integration with CAM and tooling management systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in compatible Isoturn series screw-clamp toolholders that accept WBMT-style inserts with a 520 size code.
