Carrying the DNMX432-WMX 4415 designation, this insert features a 55-degree diamond shape with a neutral hand orientation and a Wiper Edge geometry that improves surface finish at higher feed rates. The CVD multilayer coating stack — TiCN, Al2O3, and TiN — delivers heat resistance and wear resistance suited to continuous and interrupted steel cutting. With a 12.7 mm inscribed circle and a 0.79 mm corner radius, the insert handles medium to roughing-range material removal passes efficiently.\u003c\/p\u003e\u003cp\u003eThis insert is engineered primarily for steel workpieces (ISO material group P) and is also rated for cast iron (ISO material group K). The WMX chip breaker geometry is optimized for medium turning with good chip control across a range of depths of cut and feed rates. Typical applications include shaft turning, facing, and profiling on production CNC equipment in job shops, metalworking facilities, and manufacturing cells where consistent tool life and surface finish are required. Licensed machinists and CNC operators are the primary users. The ISO code for this insert is DNMX 15 04 08-WMX 4415.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for elevated wear and heat resistance\u003c\/li\u003e\n\u003cli\u003eWMX chip breaker geometry with Wiper Edge for improved surface finish at higher feeds\u003c\/li\u003e\n\u003cli\u003e55-degree diamond insert shape (Shape Code D) with neutral hand — fits a wide range of toolholders\u003c\/li\u003e\n\u003cli\u003e12.7 mm inscribed circle (0.2030 decimal inch) and 0.79 mm corner radius (0.0313 inch)\u003c\/li\u003e\n\u003cli\u003e4 usable cutting edges per insert for reduced cost per edge\u003c\/li\u003e\n\u003cli\u003eClamp and screw holding method compatible; Relief Angle N (0-degree clearance), Tolerance Code M\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in DNMX-style toolholders within the SANDVIK COROMANT T-Max P series. Primary workpiece material is steel (ISO P); secondary rated workpiece material is cast iron (ISO K). Insert Size Code 1504. Compatible toolholders must accept a 0.2030-inch hole diameter with clamp or screw holding. Verify toolholder designation against the DNMX insert shape and 3\/16-inch insert thickness before installation.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified CNC machinists or toolroom technicians. Power down and lock out the machine spindle before seating or replacing inserts. Seat the insert fully against the pocket locating surfaces before tightening the clamp or screw to avoid micro-movement under cut. Inspect the insert pocket and shim for damage or built-up material before each insert change, as pocket damage accelerates edge failure and can affect dimensional accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Designation\u003c\/strong\u003e: DNMX 432-WMX 4415\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: DNMX 15 04 08-WMX 4415\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: 55-degree Diamond (Shape Code D)\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: 4415\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: WMX (Wiper Edge)\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: 12.70 mm (0.2030 inches)\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\u003eInsert Thickness\u003c\/strong\u003e: 4.76 mm (3\/16 inch \/ 0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2030 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle (Clearance Code)\u003c\/strong\u003e: N (0 degrees)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\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 Code P)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Cast Iron (ISO Code K)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T-Max P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 5.08 inches (L) x 2.13 inches (W) x 0.53 inches (H)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.4 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: 7859249\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51727331098930,"sku":"7859249","price":399.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/600b93dbe7e67282557d6817ed721f76.jpg?v=1788676400","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7859249-turning-insert-dnmx432-wmx-4415","provider":"Voomi Supply","version":"1.0","type":"link"}
