Designated DCMT32.52-UR 4415, it carries a 55-degree diamond shape with a 7-degree relief angle and a 0.79 mm (0.0313 inch) corner radius. The insert is CVD-coated with a TiCN, Al2O3, and TiN multilayer stack under grade 4415, which targets steel as the primary workpiece material and cast iron as a secondary application. The neutral hand orientation suits straight-turning toolpaths. Two cutting edges are available per insert. This insert is part of the CoroTurn 107 series and is installed by machinists and CNC turning specialists in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is suited for medium to finishing turning passes on steel and cast iron components in both production and repair-shop settings. The UR chip breaker geometry is matched to moderate feed rates and depths of cut typical in these materials. The CoroTurn 107 series is a common platform in shops running indexable insert toolholders that accept screw- and clamp-style insert holding. The ISO code for this insert is DCMT 11 T3 08-UR 4415, and the manufacturer catalog reference is DCMT 3(2.5)2-UR 4415.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e55-degree diamond insert shape (Shape Code D) for versatile turning and profiling\u003c\/li\u003e\n\u003cli\u003eCVD multilayer coating: TiCN, Al2O3, TiN — grade 4415 for steel and cast iron\u003c\/li\u003e\n\u003cli\u003e0.79 mm corner radius for a balance of edge strength and surface finish\u003c\/li\u003e\n\u003cli\u003eNeutral hand — compatible with straight-turning toolpaths in both directions\u003c\/li\u003e\n\u003cli\u003eUR chip breaker geometry suited for medium finishing operations\u003c\/li\u003e\n\u003cli\u003eTwo usable cutting edges per insert for cost-effective indexing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CoroTurn 107 series toolholders accepting DCMT-style inserts with screw and clamp holding. The ISO designation DCMT 11 T3 08-UR 4415 can be used to cross-reference compatible toolholder bores. Primary workpiece material is steel (ISO P); secondary workpiece material is cast iron (ISO K).\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInsert installation should be performed with the machine spindle fully stopped and the machine placed in a locked or e-stop state. Use the appropriate torx or hex key specified by the toolholder manufacturer to secure the clamping screw or top clamp — do not overtighten, as this can fracture the carbide insert. Index to a fresh cutting edge only after confirming the seating pocket is clean and free of chips. Worn inserts should be removed and properly disposed of; carbide fragments are a laceration hazard.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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-degree included angle\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: 4415\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: TiCN, Al2O3, TiN (CVD process)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.79 mm (0.0313 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inches \/ 9.53 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3.97 mm (0.1563 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\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: UR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\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\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: C\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\u003eISO Code\u003c\/strong\u003e: DCMT 11 T3 08-UR 4415\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.74 x 1.54 x 0.43 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 7859117\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51751082066226,"sku":"7859117","price":256.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2f1fb3a7c11d8215c9fd01bcf00e7bb8_4031c358-f586-4627-91f8-54c72a50a30a.jpg?v=1788921566","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7859117-turning-insert-dcmt32-52-ur-4415","provider":"Voomi Supply","version":"1.0","type":"link"}
