Carrying the manufacturer grade 4415 and a multilayer CVD coating of TiCN, Al2O3, and TiN, this insert delivers thermal resistance and wear protection suited to steel and cast iron machining. It features a 55-degree diamond shape, a 0.79 mm corner radius, and a neutral hand orientation. The UF chip breaker geometry targets finishing and light-to-medium roughing cuts where chip control and surface finish are critical priorities for machinists and toolroom technicians.\u003c\/p\u003e\u003cp\u003eThis insert is part of the CoroTurn 107 series, a platform built for external longitudinal turning, facing, and profiling in both production and job-shop environments. Primary workpiece material is steel (ISO P), with cast iron (ISO K) as the secondary application. The insert fits standard DCMT-style toolholders with clamp or screw holding methods and is appropriate for finishing passes on ferrous components where dimensional accuracy and surface quality are the main performance targets.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for extended tool life on steel and cast iron\u003c\/li\u003e\n\u003cli\u003e55-degree diamond insert shape (Shape Code D) for versatile profiling and turning geometry\u003c\/li\u003e\n\u003cli\u003e0.79 mm corner radius (0.0313 inches) for finishing and light roughing applications\u003c\/li\u003e\n\u003cli\u003eUF chip breaker geometry promotes effective chip control in finishing cuts\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation compatible with a wide range of DCMT toolholder setups\u003c\/li\u003e\n\u003cli\u003e2 cutting edges per insert for cost-effective indexing in production environments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement insert for DCMT-style toolholders using clamp or screw holding methods, as specified in the CoroTurn 107 series.
