It features a triangular (60-degree included angle) geometry with a neutral hand orientation and a 1.19 mm (0.0469 inch) corner radius. The insert is CVD-coated with Al2O3, TiN, and TiCN layers, delivering high wear resistance suited for steel and cast iron machining. With three usable cutting edges and a positive side clearance, it is engineered for roughing and medium machining passes in production turning applications. Licensed machinists and CNC lathe operators install this insert in compatible CoroTurn 107 toolholders.\u003c\/p\u003e\u003cp\u003eThis insert is designed for primary use on steel workpieces (ISO material code P) and secondary use on cast iron (ISO material code K). The PM chip breaker geometry targets roughing and medium machining operations where chip control and edge durability under interrupted or continuous cuts are critical. Typical applications include external and internal profile turning in job-shop and production environments running CNC lathes or manual turret lathes. The 3\/8-inch inscribed circle and 5\/32-inch thickness place it in a mid-range insert size appropriate for moderate-depth-of-cut operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD multilayer coating: Al2O3, TiN, TiCN for extended tool life on steel and cast iron\u003c\/li\u003e\n\u003cli\u003ePM chip breaker optimized for roughing and medium machining operations\u003c\/li\u003e\n\u003cli\u003e3 usable cutting edges per insert for cost-effective tooling management\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation fits left-hand and right-hand toolholder setups\u003c\/li\u003e\n\u003cli\u003ePositive side clearance (clearance code C) reduces cutting forces and heat buildup\u003c\/li\u003e\n\u003cli\u003eCompatible with both clamp and screw insert-holding methods\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with CoroTurn 107 series toolholders accepting TCMT-style inserts with a 3\/8-inch inscribed circle.

Power down and lock out the machine spindle before seating or replacing inserts. Use the manufacturer-specified torque wrench and Torx key when tightening the clamping screw to avoid cracking the carbide substrate. Inspect the insert pocket and clamping components for wear or debris before seating a new insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: TCMT32.53\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: TCMT 16 T3 12-PM 4425\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: T - Triangle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 4425\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Finish\u003c\/strong\u003e: Al2O3, TiN, TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: PM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Roughing, Medium Machining\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1.19 mm (0.0469 inches)\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\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inches (4.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (P)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Cast Iron (K)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroTurn 107\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.44 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.74 x 1.54 x 0.44 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Package Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: 7861071\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51734687809842,"sku":"7861071","price":290.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d984c8a7818954f1cdc6640d9e128210_5a0ae596-b486-4540-9958-74dbc6b67fa9.jpg?v=1788764861","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7861071-turning-insert-tcmt32-53-pm-4425","provider":"Voomi Supply","version":"1.0","type":"link"}
