Manufactured under the CoroTurn 107 series, this insert carries a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, providing wear resistance and thermal stability across a range of cutting speeds. The insert has an 80-degree diamond shape (Insert Shape Code C), a 9.53 mm inscribed circle, and a 0.4 mm corner radius. It is neutral-hand, making it adaptable to both left- and right-hand toolholders. Cutting edge count is 2, maximizing tool economy per insert. The ISO code for this insert is CCMT 09 T3 04-PF 4425.\u003c\/p\u003e\u003cp\u003eThis insert is rated primarily for steel (ISO material group P) and secondarily for cast iron (ISO material group K), covering the most common workpiece materials encountered in general machining, job shop, and production turning environments. The PF chip breaker geometry is suited for finishing and light roughing passes where chip control and surface finish are critical. Grade 4425 is a CVD-coated carbide grade developed for stable, moderate-to-high cutting speed applications in steel. Machinists and CNC operators in production shops, tool rooms, and maintenance machining will find this insert appropriate for shaft work, flanges, and general-purpose turned components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for wear resistance and thermal protection\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape (CCMT) with 7-degree relief angle for positive cutting geometry\u003c\/li\u003e\n\u003cli\u003ePF chip breaker geometry optimized for finishing and light roughing on steel\u003c\/li\u003e\n\u003cli\u003e9.53 mm inscribed circle with 0.4 mm corner radius for fine feature turning\u003c\/li\u003e\n\u003cli\u003e2 cutting edges per insert for cost-effective tool management\u003c\/li\u003e\n\u003cli\u003eClamp and screw holding method for secure seating in compatible toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CCMT-compatible toolholders within the CoroTurn 107 series.
