Running under the CoroTurn 107 series designation DCMX 11T3 04-WM 4415, this insert features a 55-degree diamond shape with a 7-degree relief angle and a 0.4 mm (0.0156 inch) corner radius. The CVD coating stack — TiCN, Al2O3, and TiN — delivers a layered wear-resistance profile suited to continuous and interrupted cuts on steel and cast iron. The WM chip breaker geometry and wiper edge are engineered to control chip flow and surface finish at medium cutting parameters. Licensed machinists and CNC operators install this insert in compatible CoroTurn 107 toolholders.\u003c\/p\u003e\u003cp\u003eThis insert is built for medium turning of steel (ISO material group P) as its primary application and cast iron (ISO material group K) as a secondary application. The WM chip breaker makes it well suited to medium-depth finishing and semi-finishing passes where chip control and surface finish are priorities. Its neutral hand orientation and clamp-and-screw holding method fit standard 11T3-size toolholder pockets used on turning centers and engine lathes in both production and job-shop environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for thermal and abrasion resistance\u003c\/li\u003e\n\u003cli\u003e55-degree diamond insert shape (ISO shape code D) for versatile turning geometry\u003c\/li\u003e\n\u003cli\u003eWM chip breaker with wiper edge for controlled chip formation and improved surface finish\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation compatible with standard 11T3-pocket toolholders\u003c\/li\u003e\n\u003cli\u003eClamp and screw holding method for secure seating under interrupted and continuous cuts\u003c\/li\u003e\n\u003cli\u003eTwo cutting edges per insert to extend tooling value per unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CoroTurn 107 series toolholders accepting DCMX 11T3-size inserts with clamp and screw holding.

Always power down and lock out the spindle before indexing or replacing inserts. Inspect the toolholder pocket and clamping screw for wear or debris before seating a new insert. Refer to the applicable cutting data recommendations for the 4415 grade when setting speeds, feeds, and depth of cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: DCMX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: DCMX 11 T3 04-WM 4415\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: 55-Degree Diamond (Code D)\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\u003eChip Breaker\u003c\/strong\u003e: WM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWiper Edge\u003c\/strong\u003e: Yes\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: 9.53 mm (0.1732 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.40 mm (0.0156 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\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\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\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\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Screw\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\u003eSeries\u003c\/strong\u003e: CoroTurn 107\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: 0.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: 7859123\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51746553528626,"sku":"7859123","price":315.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/605a61f9d892a373a71eb35f944345b7.jpg?v=1788871241","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7859123-turning-insert-dcmx-4415-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
