It carries an ISO designation of TCMT 11 03 04-MM 2220 and features a multilayer CVD coating of TiCN, Al2O3, and TiN applied over a carbide substrate in grade 2220. The triangular insert shape provides three cutting edges, and the MM chip breaker geometry is optimized for stainless steel and other ISO M-group workpiece materials. With a 1\/4-inch inscribed circle and a 1\/64-inch corner radius, this insert suits medium finishing and light roughing passes where edge sharpness and chip control are critical.\u003c\/p\u003e\n\u003cp\u003eThis insert is primarily intended for machining stainless steel (ISO material group M) in production turning environments. Typical applications include external longitudinal turning and facing on CNC lathes in job shops, general machining facilities, and manufacturing operations where consistent surface finish and tool life on difficult-to-machine alloys are priorities. The neutral hand orientation makes it compatible with standard right-hand toolholders accepting TCMT-style inserts. The screw-on insert holding method suits standard TCMT toolholder clamps with the appropriate screw and wrench.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for wear resistance and heat management on stainless steel\u003c\/li\u003e\n  \u003cli\u003eMM chip breaker geometry engineered for effective chip control on ISO M-group materials\u003c\/li\u003e\n  \u003cli\u003eThree usable cutting edges per insert from the 60-degree triangular shape\u003c\/li\u003e\n  \u003cli\u003e1\/64-inch (0.40 mm) corner radius suited to medium finishing and light roughing cuts\u003c\/li\u003e\n  \u003cli\u003eScrew-on mounting method for secure, repeatable insert indexing\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation compatible with standard TCMT right-hand turning toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in TCMT-style screw-clamp turning toolholders accepting inserts with a 1\/4-inch inscribed circle, 1\/8-inch thickness, and a 2.80 mm (0.1102 inch) hole diameter.

Use the manufacturer-specified torque wrench and insert screw to seat the insert firmly without over-torquing the mounting screw. Inspect the insert pocket and seating surface for chips or wear before installing a new insert, as contamination will affect edge position and surface finish. Follow facility lockout\/tagout procedures before any tooling change at the spindle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: TCMT 11 03 04-MM 2220\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TCMT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (60 degrees)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape Code\u003c\/strong\u003e: T\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 (CVD process)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel (ISO Code M)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/4 inch (0.2500 inch \/ 6.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0156 inch \/ 0.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/8 inch (0.1250 inch \/ 3.17 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1102 inch (2.80 mm)\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 Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWiper Edge\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroTurn 107\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 221\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 7231447\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51732295975218,"sku":"7231447","price":218.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2228d3b6e61744851f81f9f51cffed5_eaebfddf-4bcf-4ebd-9db6-84c921210439.jpg?v=1788741308","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7231447-turning-insert-tcmt221-mm-2220","provider":"Voomi Supply","version":"1.0","type":"link"}
