It carries the grade designation 2220 and features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN for extended wear resistance and thermal stability. The insert has a neutral hand orientation, an 80-degree diamond shape (Insert Shape Code C), a 3\/8-inch inscribed circle, a 5\/32-inch thickness, and a 1\/32-inch corner radius. Part of the CoroTurn 107 series, this insert is held in place by a screw-clamping method and is intended for installation by machinists or tooling technicians working in production or job-shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is optimized for turning stainless steel and other ISO M-group workpiece materials, making it well suited for applications where built-up edge resistance and chip control are critical. The MM chip breaker geometry is engineered to manage chip flow across a range of depths of cut and feed rates typical of stainless steel finishing and semi-finishing passes. It is appropriate for both high-volume production turning and precision part work where surface finish and dimensional consistency are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD multilayer coating — TiCN, Al2O3, and TiN — provides wear resistance and heat barrier for extended tool life on stainless steel\u003c\/li\u003e\n\u003cli\u003eMM chip breaker geometry promotes reliable chip control during finishing and semi-finishing cuts\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape (CCMT) delivers a strong cutting edge with moderate approach angle flexibility\u003c\/li\u003e\n\u003cli\u003e7-degree relief angle (Clearance Code C) reduces flank wear in tight-tolerance turning applications\u003c\/li\u003e\n\u003cli\u003eScrew-clamping insert holding method ensures repeatable seating and quick indexing between cutting edges\u003c\/li\u003e\n\u003cli\u003eTwo cutting edges per insert reduce per-edge tooling cost in production environments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CoroTurn 107 series toolholders that accept CCMT 09 T3 08 inserts (ISO code CCMT 09 T3 08-MM 2220). Compatible toolholders must accommodate a screw-clamping insert holding method and the CCMT insert geometry with a 0.1732-inch hole diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC tooling technicians. Before indexing or replacing inserts, ensure the machine spindle is fully stopped and the control is in a safe state. Use the appropriate Torx or hex key specified by the toolholder manufacturer to seat the clamping screw to proper engagement — do not overtighten, as this can fracture the carbide insert. Verify insert seating and pocket cleanliness before resuming cuts, and confirm that the replacement insert grade and geometry match the application requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CCMT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroTurn 107\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 2220\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: 80-degree Diamond (Code C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 5\/32 inches (0.1563 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inches (0.0313 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel (ISO Group M)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CCMT 09 T3 08-MM 2220\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SANDVIK COROMANT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7231311\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51737468600626,"sku":"7231311","price":207.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/28c9430d43e17b61805bf294c76b621f_e513293b-170a-4994-8dcb-0e07c0d28c99.jpg?v=1788788925","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7231311-turning-insert-ccmt32-52-mm-2220","provider":"Voomi Supply","version":"1.0","type":"link"}
