The insert is manufactured from solid carbide with a CVD-applied multilayer coating consisting of Al2O3, TiN, and TiCN, corresponding to manufacturer grade 4425. This coating stack delivers wear resistance and thermal stability suited for continuous and light interrupted cuts. With a 3\/8-inch (0.3750 inch) inscribed circle, a 0.4 mm (0.0156 inch) corner radius, and a 60-degree included angle, this insert fits standard TCMT toolholders and provides three usable cutting edges per insert. The neutral hand orientation and UR chip breaker geometry are matched to general steel and cast iron turning.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for medium-duty turning of steel and cast iron workpieces in production and job-shop environments. The UR chip breaker geometry is optimized for reliable chip control across a range of depths of cut and feed rates typical in finishing to semi-finishing passes. The grade 4425 with CVD coating is classified under ISO material group P (steel) as the primary application and group K (cast iron) as secondary. It is installed by licensed machinists and CNC operators in shops running TCMT-compatible toolholder systems within the CoroTurn 107 platform.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD multilayer coating: Al2O3, TiN, and TiCN for thermal and abrasion resistance\u003c\/li\u003e\n  \u003cli\u003eGrade 4425 carbide substrate suited for steel (ISO P) and cast iron (ISO K) turning\u003c\/li\u003e\n  \u003cli\u003e60-degree triangular shape with 3 usable cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003eUR chip breaker geometry for controlled chip evacuation in finishing and semi-finishing\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation compatible with standard TCMT toolholder pockets\u003c\/li\u003e\n  \u003cli\u003eClamp and screw insert holding method for rigid, repeatable seating\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in TCMT-compatible toolholders within the CoroTurn 107 series.

Power down and lock out the machine spindle before seating or removing inserts. Use the correct torx or hex key torque driver as specified by the toolholder manufacturer for the clamping screw — do not overtighten. Inspect the toolholder pocket for wear or debris before seating a new insert to ensure proper contact and repeatability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 4425\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: 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\u003eInsert Shape\u003c\/strong\u003e: Triangle (60-degree 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: UR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.4 mm (0.0156 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 5\/32 inch (0.1563 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inch (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\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\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\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: TCMT 16 T3 04-UR 4425\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: 0.44 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.54 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3.74 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.44 inches\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: 7861132\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51744572014898,"sku":"7861132","price":289.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/beae66744267016daa532069d65dce0e_0c1170ed-37f1-45b5-a0a0-0f4a74a19315.jpg?v=1788858402","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7861132-turning-insert-tcmt32-51-ur-4425","provider":"Voomi Supply","version":"1.0","type":"link"}
