Manufactured under the CoroTurn 107 series, it features a triangular insert shape with a 60-degree included angle and a neutral hand orientation. The insert carries a multilayer CVD coating of TiCN, Al2O3, and TiN, which delivers wear resistance and thermal stability during continuous and light interrupted cuts. The manufacturer grade is 4335, optimized for steel applications identified under ISO material code P. The screw-clamped holding method provides secure, repeatable positioning in compatible toolholders. This insert is installed by machinists and CNC turning center operators in production and job shop environments.\u003c\/p\u003e\u003cp\u003eThe 7080712 is suited for turning steel components in both light finishing and moderate roughing passes. It is used in CNC lathes and turning centers where the CoroTurn 107 toolholder system is employed. The PM chip breaker geometry controls chip flow across a range of feed rates and depths of cut, making this insert practical for medium-duty steel turning tasks. With 3 cutting edges per insert, it offers multiple index positions before replacement, reducing per-edge tooling cost in production settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for wear and heat resistance on steel\u003c\/li\u003e\n\u003cli\u003ePM chip breaker geometry for controlled chip evacuation in steel turning\u003c\/li\u003e\n\u003cli\u003e3 cutting edges per insert for extended usable tool life per piece\u003c\/li\u003e\n\u003cli\u003e0.0156-inch (1\/64-inch) corner radius for finishing and medium-duty passes\u003c\/li\u003e\n\u003cli\u003eScrew-clamped insert holding method for rigid, repeatable seating\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation compatible with standard right-hand and left-hand toolholder setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with CoroTurn 107 series toolholders that accept TCMT-style inserts with a screw clamping method.

Use the correct Torx or hex key specified by the toolholder manufacturer to secure the clamping screw — do not overtighten, as this can fracture the insert. Inspect the toolholder seat and shim for damage before installing a new insert. Follow shop-specific safe work procedures and machine tool manufacturer guidelines when changing inserts on live tooling systems.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TCMT\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: 4335\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: 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: Triangle (60 degrees included angle)\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: PM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0156 inches (1\/64 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.2500 inches (1\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1250 inches (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1102 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 Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (ISO Code P)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: TCMT 11 03 04-PM 4335\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 221\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 7080712\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51747681632562,"sku":"7080712","price":31.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2228d3b6e61744851f81f9f51cffed5_ebb3563e-f284-475f-b20e-60ec3ebe2314.jpg?v=1788884468","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7080712-turning-insert-tcmt221-pm-4335","provider":"Voomi Supply","version":"1.0","type":"link"}
