Identified by ISO code TCMT 11 02 04-UF 4415, this insert features a triangular shape with a 60-degree included angle, a 7-degree relief angle, and a 0.40 mm corner radius. The multilayer CVD coating stack of Al2O3, TiN, and TiCN provides wear resistance and thermal stability during cutting. Machinists and CNC operators in production shops use this insert for consistent, reliable metal removal on steel and cast iron workpieces.\u003c\/p\u003e\u003cp\u003eThis insert is suited for finish to semi-finish turning of steel and cast iron components in both light and moderate cutting conditions. The UF chip breaker geometry is optimized for light cutting depths and small feeds, making it a practical choice for close-tolerance finishing passes. It fits toolholders and boring bars that accept screw or clamp holding methods compatible with the TCMT insert style. The neutral hand orientation allows use in a range of standard turning applications without handedness restrictions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with manufacturer grade 4415 for steel and cast iron applications\u003c\/li\u003e\n\u003cli\u003eCVD-applied multilayer coating: Al2O3, TiN, and TiCN for wear and heat resistance\u003c\/li\u003e\n\u003cli\u003eUF chip breaker geometry for light finishing cuts and tight tolerances\u003c\/li\u003e\n\u003cli\u003eTriangle insert shape with 60-degree included angle and 3 usable cutting edges\u003c\/li\u003e\n\u003cli\u003e0.40 mm corner radius for finish turning with controlled surface finish\u003c\/li\u003e\n\u003cli\u003eNeutral hand insert compatible with screw and clamp toolholder styles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement turning insert for CoroTurn 107 series toolholders accepting TCMT-style inserts with a 0.1102-inch hole diameter and screw or clamp holding.

Power down and lock out the machine spindle before changing inserts. Use the correct torque driver and insert screw specified for the toolholder to avoid cracking the carbide substrate or stripping the clamping screw. Inspect the toolholder seat and clamping surfaces for debris or wear before seating the new insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: TCMT 11 02 04-UF 4415\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\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\u003eCorner Radius\u003c\/strong\u003e: 0.40 mm (0.0156 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/32 inch (0.0938 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1102 inches (2.80 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 Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 4415\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Al2O3, TiN, TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: UF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (ISO P)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Cast Iron (ISO K)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroTurn 107\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\u003eWeight\u003c\/strong\u003e: 0.44 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: 7860483\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51748299276594,"sku":"7860483","price":216.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/91a41fdad8f15f3ae27b0a0e9076abaf_a5915ec1-1073-44eb-8731-351b77a01aa9.jpg?v=1788892004","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7860483-turning-insert-tcmt21-51-uf-4415","provider":"Voomi Supply","version":"1.0","type":"link"}
