It features a TiAlN and AlCr2O3 coating applied via PVD process, delivering thermal resistance and wear performance for demanding cutting applications. The insert carries a 55-degree diamond shape with a 7-degree relief angle, a 3\/8-inch inscribed circle, and a 1\/64-inch corner radius. Holding method is screw-style. This insert is designed for CNC turning operations and is installed by machinists and tooling specialists working on lathes and turning centers.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning operations on stainless steel as its primary workpiece material, with secondary applications in superalloys and titanium. The UM chip breaker geometry is optimized for these difficult-to-machine materials where controlled chip formation and edge security are critical. It is a neutral-hand insert applicable to standard external and internal turning setups in both production and job-shop environments. The ISO designation is DCMT 11 T3 04-UM 1115.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiAlN and AlCr2O3 PVD coating for high heat and wear resistance in stainless and superalloy cutting\u003c\/li\u003e\n\u003cli\u003e55-degree diamond insert shape with 7-degree relief angle for positive cutting geometry\u003c\/li\u003e\n\u003cli\u003eUM chip breaker geometry engineered for controlled chip evacuation in tough materials\u003c\/li\u003e\n\u003cli\u003e3\/8-inch inscribed circle with 1\/64-inch corner radius for precise finishing and semi-finishing passes\u003c\/li\u003e\n\u003cli\u003eScrew-type insert holding method for secure clamping on compatible toolholders\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation for versatile use in multiple turning setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in DCMT-style screw-clamped toolholders compatible with the CoroTurn 107 series.

Power down and lock out the machine spindle before seating or replacing inserts. Use the appropriate torx or hex key to torque the clamping screw to the toolholder manufacturer specification — do not overtighten, as this can fracture the carbide insert. Inspect the toolholder pocket for wear or debris before seating a new insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: DCMT 11 T3 04-UM 1115\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: DCMT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond, 55 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 1115\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 Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0156 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.442 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 5\/32 inch (0.1563 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inches\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: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Superalloy, Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroTurn 107\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: 0.13 pounds\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: 5730978\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51752943092018,"sku":"5730978","price":240.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/49a341a51192e9f50193c690b0d90852_aa2e8db7-4b11-41b5-bd4a-711f414d21d5.jpg?v=1788931357","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5730978-turning-insert-dcmt-1115","provider":"Voomi Supply","version":"1.0","type":"link"}
