It carries a dual-layer PVD coating of TiAlN and AlCr2O3, which provides thermal resistance and wear protection at elevated cutting temperatures. The insert features a 35-degree diamond shape, a 3\/8-inch inscribed circle, a 1\/64-inch corner radius, and a neutral hand orientation. The SF chip breaker geometry targets demanding workpiece materials where chip control and edge stability are critical. Machining professionals and CNC setup technicians install this insert in compatible toolholders using clamp and pin holding methods.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered primarily for stainless steel (ISO material code M) and is also rated for superalloys and titanium (ISO material code S). These are among the most thermally and mechanically demanding materials in precision machining, making the PVD-coated carbide substrate and SF chip breaker geometry particularly well matched. Typical applications include turning shafts, flanges, fittings, and aerospace or medical components where surface finish and dimensional tolerance are tightly controlled. It is sold individually but carries a minimum order quantity of 10 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePVD-applied TiAlN and AlCr2O3 dual-layer coating for thermal stability and flank wear resistance\u003c\/li\u003e\n  \u003cli\u003eSF chip breaker geometry optimized for stainless steel, superalloys, and titanium\u003c\/li\u003e\n  \u003cli\u003e35-degree diamond insert shape (V) with neutral hand for versatile turning approaches\u003c\/li\u003e\n  \u003cli\u003e1\/64-inch (0.0156-inch) corner radius for controlled surface finish\u003c\/li\u003e\n  \u003cli\u003eClamp and pin insert holding method for rigid, repeatable seating\u003c\/li\u003e\n  \u003cli\u003e4 cutting edges per insert for extended tool life per unit cost\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in VNMG-compatible turning toolholders that accept a 3\/8-inch inscribed circle insert with clamp and pin retention.

Power down and lock out the machine spindle before changing inserts. Seat the insert fully in the toolholder pocket and secure the clamp and pin to the toolholder manufacturer's specified torque before starting a cut. Inspect the cutting edge and coating condition at each insert index; a damaged or worn edge should be indexed or replaced rather than returned to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: VNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: VNMG 16 04 04-SF 1115\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 1115\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN and AlCr2O3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (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\u003eChip Breaker\u003c\/strong\u003e: SF\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\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inches (0.0156 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.0945 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\u003eHole Diameter\u003c\/strong\u003e: 0.1500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel (ISO Code M)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Superalloy and Titanium (ISO Code S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T-Max P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.27 pounds\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\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: 5891431\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51740072378674,"sku":"5891431","price":557.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9bcdc2792d716afcf62a82be965e869e.jpg?v=1788822087","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5891431-turning-insert-vnmg331-sf-1115","provider":"Voomi Supply","version":"1.0","type":"link"}
