The insert features a 35-degree diamond shape (V-shape code) with a 3\/8-inch inscribed circle and a 0.40 mm corner radius. The neutral hand orientation and PF chip breaker geometry make this insert suited for finishing and light finishing passes on steel and cast iron workpieces. Licensed machinists and CNC lathe operators install this insert in compatible CoroTurn 107 toolholders.\u003c\/p\u003e\n\u003cp\u003eThis insert is designed for external turning operations on steel (ISO material code P) as the primary workpiece material and cast iron (ISO material code K) as the secondary workpiece material. The PF chip breaker is optimized for finishing cuts requiring tight tolerances and consistent chip control. It is well suited for light-depth, close-tolerance turning applications in production and job-shop CNC environments. The insert uses a clamp-and-screw holding method and carries tolerance code M with clearance code B.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD-applied multilayer coating: Al2O3, TiN, and TiCN for extended wear resistance on steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eGrade 4425 solid carbide substrate suited for finishing on ISO P and K materials\u003c\/li\u003e\n  \u003cli\u003e35-degree diamond insert shape with 0.40 mm corner radius for precision finishing geometry\u003c\/li\u003e\n  \u003cli\u003ePF chip breaker promotes controlled chip evacuation during light finishing passes\u003c\/li\u003e\n  \u003cli\u003e2 cutting edges per insert; neutral hand orientation for flexible toolholder setups\u003c\/li\u003e\n  \u003cli\u003eClamp-and-screw holding method provides secure seating in CoroTurn 107 toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with SANDVIK COROMANT CoroTurn 107 series toolholders accepting VBMT-style inserts.
