The insert carries a TiAlN and AlCr2O3 dual-layer coating applied via PVD process, which supports elevated cutting temperatures and edge wear resistance. It features a 35-degree diamond shape (V), a UM chip breaker geometry, and a neutral hand orientation. At 0.638 inches in length with a 3\/8-inch inscribed circle, this insert is sized for medium-duty turning passes on steel and a range of secondary workpiece materials. Machining professionals and CNC operators install this insert in compatible screw-clamp toolholders.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning steel as its primary workpiece material, with additional capability across stainless steel, non-ferrous metals, superalloys, and titanium. The UM chip breaker geometry is optimized for finishing and light roughing passes where chip control and surface finish consistency are priorities. The insert is used in production and job-shop turning environments on both horizontal and vertical turning centers. ISO code VBMT 16 04 04-UM 1125 allows cross-referencing with toolholder and insert grade catalogs for direct application matching.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTiAlN and AlCr2O3 PVD coating for extended tool life on steel and superalloys\u003c\/li\u003e\n  \u003cli\u003e35-degree diamond insert shape (V) enables tight profiling and contour turning\u003c\/li\u003e\n  \u003cli\u003eUM chip breaker geometry supports finishing and light roughing with controlled chip flow\u003c\/li\u003e\n  \u003cli\u003eScrew-clamp holding method provides positive insert location and repeatability\u003c\/li\u003e\n  \u003cli\u003e2 cutting edges per insert; neutral hand for flexible toolholder pairing\u003c\/li\u003e\n  \u003cli\u003e1\/64-inch corner radius (0.0156 inches) suited for detail passes and shoulder blending\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in screw-clamp VBMT-style toolholders compatible with the CoroTurn 107 series. ISO insert designation VBMT 16 04 04-UM 1125 governs toolholder and adapter selection.

Isolate machine power and confirm spindle stop before changing inserts. Use the correct Torx or hex key to secure the clamping screw to the toolholder manufacturer's specified procedure — do not overtighten or cross-thread the screw. Inspect the insert pocket and seating surface for chips or debris before seating the new insert to ensure proper clamping and runout control.\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\u003eISO Code\u003c\/strong\u003e: VBMT 16 04 04-UM 1125\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: 1125\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\u003eChip Breaker\u003c\/strong\u003e: UM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: 35-Degree Diamond (V)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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\u003eInsert Length\u003c\/strong\u003e: 0.638 inches (16.21 mm)\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\/64 inches (0.0156 inches)\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\u003eRelief Angle\u003c\/strong\u003e: 5 degrees\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\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (P)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Non-Ferrous Metal, Superalloy, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 331\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.24 pounds\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: 5755684\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51730420465970,"sku":"5755684","price":424.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/13cda698584605ece421afa8ce4e8c0f.jpg?v=1788717137","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5755684-turning-insert-vbmt331-um","provider":"Voomi Supply","version":"1.0","type":"link"}
