It features a 35-degree diamond insert shape with a neutral hand orientation and a 3\/8-inch inscribed circle. The insert is CVD-coated with a multilayer Al2O3, TiCN, and TiN stack and carries manufacturer grade 4425, making it suited for productive turning on steel and cast iron workpieces. The UR chip breaker geometry controls chip flow across a range of depths and feed rates. Two cutting edges per insert are available before the insert is indexed or replaced. Licensed machinists and CNC lathe operators are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis insert is designed for external and internal turning operations on steel (ISO P) and cast iron (ISO K) materials. It is positioned in the CoroTurn 107 toolholder system, which uses a clamp and screw holding method. Typical applications include finishing and semi-finishing passes where consistent surface finish and tool life are priorities. The 1\/32-inch corner radius supports moderate-to-light chip loads and is well suited for lower-depth finishing cuts where edge stability and coating integrity matter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD-applied multilayer coating: Al2O3, TiCN, and TiN for wear resistance on steel and cast iron\u003c\/li\u003e\n  \u003cli\u003e35-degree diamond (V) insert shape with 5-degree relief angle for clearance in tight approach angles\u003c\/li\u003e\n  \u003cli\u003eUR chip breaker geometry for controlled chip evacuation across a range of feed rates\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch inscribed circle and 3\/16-inch insert thickness for CoroTurn 107 toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation — usable on right- or left-hand tooling setups\u003c\/li\u003e\n  \u003cli\u003eTwo cutting edges per insert, indexed via clamp and screw holding method\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CoroTurn 107 series toolholders that accept VBMT-style inserts.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque wrench and manufacturer-specified seating hardware for the CoroTurn 107 toolholder — do not overtighten the clamping screw, as this can fracture the insert or damage the seat. Inspect the pocket seat and shim for debris or wear before seating a new insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: VBMT\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\u003eInsert Shape\u003c\/strong\u003e: Diamond (35 degrees)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape Code\u003c\/strong\u003e: V\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inches (0.375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inches (0.0313 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 5 degrees\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\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: UR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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 Holding Method\u003c\/strong\u003e: Clamp and 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\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\u003eISO Code\u003c\/strong\u003e: VBMT 16 04 08-UR 4425\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 5.08 inches (L) x 2.13 inches (W) x 0.54 inches (H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.54 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: 7861136\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51728813490482,"sku":"7861136","price":380.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/62194bfce7eddd678021bbeeb2af97c8.jpg?v=1788696304","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7861136-turning-insert-vbmt332-ur-4425","provider":"Voomi Supply","version":"1.0","type":"link"}
