Manufactured from solid carbide and coated via CVD with a TiCN, Al2O3, and TiN multilayer system, this insert carries the manufacturer grade designation 2220, positioning it for steel and general-purpose turning applications where wear resistance and thermal stability are critical. The insert features an 80-degree diamond shape (shape code C), a neutral hand orientation, a 3\/4-inch inscribed circle, and a 3\/64-inch corner radius. It belongs to SANDVIK COROMANT T-Max P series and is identified by ISO code CNMG 19 06 12-MM 2220 with the MM chip breaker geometry.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for medium to roughing turning passes on steel and similar workpiece materials in production machining environments. The MM chip breaker geometry promotes controlled chip flow across a range of feeds and depths of cut, making it a practical choice for shops running moderate material removal rates on steel components. Machinists and CNC operators working in job shops, production facilities, and maintenance machining operations are the primary installers of this insert. It is sold individually and packaged as a quantity of one.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for elevated wear resistance and thermal barrier performance\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape provides a strong cutting edge with good approach angle versatility\u003c\/li\u003e\n  \u003cli\u003e3\/64-inch (0.0469 inch) corner radius balances surface finish capability with edge strength\u003c\/li\u003e\n  \u003cli\u003eMM chip breaker geometry supports controlled chip evacuation across varied feed rates\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation allows use on both right-hand and left-hand tool holders\u003c\/li\u003e\n  \u003cli\u003eCNMG tolerance and M tolerance code ensure consistent seating and repeatable insert indexing\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp and pin insert holding methods for secure fixturing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to fit CNMG-style tool holders that accept a 3\/4-inch inscribed circle insert with clamp or pin holding methods.
