It features a 35-degree diamond shape (V), a neutral hand orientation, and a 0.20 mm (0.0079 inch) corner radius suited for finishing and semi-finishing passes. The insert is manufactured from solid carbide with a CVD-applied multilayer coating of Al2O3, TiCN, and TiN, giving it strong wear resistance and thermal stability. It carries manufacturer grade 4425 and belongs to the CoroTurn 107 series. The inscribed circle measures 1\/4 inch (0.2500 inch) and the insert thickness is 3\/32 inch (0.0938 inch). Licensed machinists and CNC operators use this insert in production turning of steel and cast iron components.\u003c\/p\u003e\u003cp\u003eThis insert is intended for turning steel (ISO material group P) as the primary workpiece material and cast iron (ISO material group K) as a secondary application. The UF chip breaker geometry is optimized for light to medium cutting depths with controlled chip formation, making it well suited for finishing operations where surface finish and dimensional accuracy are priorities. It is compatible with clamp and screw holding methods on tool holders designed to accept VBMT 11 02 02 geometry inserts. The CoroTurn 107 series is a widely used platform for external and internal profiling on both manual and automated turning equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e35-degree diamond insert shape (V) with neutral hand for versatile external turning\u003c\/li\u003e\n\u003cli\u003eCVD multilayer coating: Al2O3, TiCN, and TiN for thermal resistance and edge wear protection\u003c\/li\u003e\n\u003cli\u003eManufacturer grade 4425 rated for steel (P) and cast iron (K) workpiece materials\u003c\/li\u003e\n\u003cli\u003eUF chip breaker geometry designed for finishing and semi-finishing operations\u003c\/li\u003e\n\u003cli\u003e0.20 mm corner radius for improved surface finish on finished bores and diameters\u003c\/li\u003e\n\u003cli\u003eCompatible with clamp and screw holding methods; no wiper edge\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-specification insert for tool holders accepting VBMT 11 02 02 geometry within the Sandvik Coromant CoroTurn 107 series.

Power down the machine and follow lockout\/tagout procedures before seating or replacing inserts. Ensure the pocket and clamping surfaces are clean and free of chips before installing the insert. Use the appropriate torque driver for the clamp or screw holding method per the tool holder manufacturer specifications; do not overtighten, as carbide inserts are brittle and can fracture under excessive clamping force.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: VBMT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: VBMT 11 02 02-UF 4425\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (V), 35-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\u003eManufacturer Grade\u003c\/strong\u003e: 4425\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Al2O3, TiCN, TiN\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\u003eCorner Radius\u003c\/strong\u003e: 0.20 mm (0.0079 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: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 5 degrees\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\u003eHolding Method\u003c\/strong\u003e: Clamp and Screw\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 inches L x 1.54 inches W x 0.44 inches H\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: 7861115\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51729509810482,"sku":"7861115","price":355.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bfe8306f4924da99cf8b0c61e0a3dd9f_a0769471-5964-4ea1-aaaf-6e8b82b09c1d.jpg?v=1788705450","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7861115-turning-insert-vbmt21-50-uf-4425","provider":"Voomi Supply","version":"1.0","type":"link"}
