Manufactured in a 55-degree diamond (D) shape with a DCGT insert style, it carries a 1125 grade PVD-applied TiAlN and AlCr2O3 dual-layer coating for wear resistance and thermal stability. The insert features a UM chip breaker geometry optimized for finishing cuts on steel and a range of secondary workpiece materials. With a 1\/4-inch inscribed circle and a 1\/32-inch corner radius, it is suited for light, close-tolerance material removal where surface finish matters. CNC machinists and toolroom technicians are the primary end users.\u003c\/p\u003e\n\u003cp\u003eThis insert belongs to the CoroTurn 107 series and is intended for screw-clamped toolholders in external turning and profiling applications. Its neutral hand orientation makes it adaptable across a range of toolholder configurations. Primary workpiece material is steel (ISO code P), with rated secondary suitability for stainless steel, non-ferrous metals, superalloys, and titanium (ISO codes M, N, S). It is well-suited for finishing passes where tight dimensional tolerances and consistent chip control are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1125 grade carbide with PVD-applied TiAlN and AlCr2O3 dual-layer coating for extended tool life on steel\u003c\/li\u003e\n  \u003cli\u003eUM chip breaker geometry engineered for finishing operations with reliable chip control\u003c\/li\u003e\n  \u003cli\u003e55-degree diamond insert shape (ISO code D) supports profiling and contour turning\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation for flexible toolholder compatibility within CoroTurn 107 screw-clamp systems\u003c\/li\u003e\n  \u003cli\u003e1\/32-inch corner radius for fine surface finish requirements\u003c\/li\u003e\n  \u003cli\u003eTwo cutting edges per insert\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in SANDVIK COROMANT CoroTurn 107 series screw-clamped toolholders accepting DCGT-style inserts with a 1\/4-inch inscribed circle.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct Torx or hex key driver as specified by the toolholder manufacturer for the clamp screw — do not overtighten. Inspect the insert pocket and seating surface for chips or debris before seating the new insert to ensure accurate positioning and prevent premature edge failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: DCGT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: DCGT 07 02 08-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: Diamond (55 degrees included angle)\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: 1\/4 inch (0.2500 inches \/ 6.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inch (0.0313 inches \/ 0.79 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.2737 inches (6.95 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/32 inch (0.0938 inches \/ 2.38 mm)\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\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: G\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\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 Materials\u003c\/strong\u003e: Steel, Stainless Steel, Non-Ferrous Metal, Superalloy, Titanium (ISO M, N, P, S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWiper Edge\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: 5730439\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51750473761074,"sku":"5730439","price":422.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/49a341a51192e9f50193c690b0d90852_33dd54b4-ffed-4b87-ba9b-8a7978ca7542.jpg?v=1788915727","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5730439-turning-insert-dcgt-1125","provider":"Voomi Supply","version":"1.0","type":"link"}
