It carries an 80-degree diamond shape (C) with a 7-degree relief angle and a 0.4 mm corner radius. The insert features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which delivers thermal resistance and wear protection during moderate to high cutting speeds. Holding method is clamp or screw, and the PF chip breaker geometry is optimized for light to medium finishing cuts on steel and cast iron workpieces.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for finishing and semi-finishing passes in both residential shop and industrial production environments. The PF chip breaker is engineered specifically for steel (ISO material group P) as the primary workpiece material, with secondary suitability for cast iron (ISO material group K). Typical applications include shaft turning, bore finishing, and profile work where controlled chip evacuation and surface finish consistency are priorities. Licensed machinists and CNC operators install this insert as a direct replacement in CoroTurn 107 compatible toolholders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e80-degree diamond insert shape with 7-degree relief angle for versatile turning geometry\u003c\/li\u003e\n  \u003cli\u003eCVD multilayer coating: TiCN, Al2O3, TiN for thermal and abrasion resistance\u003c\/li\u003e\n  \u003cli\u003ePF chip breaker geometry optimized for light to medium finishing cuts\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation for flexible toolholder pairing\u003c\/li\u003e\n  \u003cli\u003eTwo cutting edges per insert for extended service life\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp and screw holding methods\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CoroTurn 107 series toolholders accepting CCMT 09 T3 geometry inserts.
