It carries the ISO designation DNMG 15 04 04-PF 4415 and features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN over a solid carbide substrate. The 55-degree diamond insert shape and PF chip breaker geometry make it well suited for finishing and light-to-medium roughing passes. With four available cutting edges and a 0.40 mm corner radius, this insert delivers consistent surface finish and tool life in production turning environments. It belongs to the T-Max P series, engineered for reliable clamping in both clamp and screw-lock toolholders.\u003c\/p\u003e\n\u003cp\u003eThis insert is used primarily in CNC turning centers and manual lathes performing external and internal turning operations. The 4415 grade is optimized for steel as its primary workpiece material (ISO P), with cast iron (ISO K) as a secondary application. It fits toolholders with a 0.5000-inch (12.70 mm) inscribed circle seating and is appropriate for shops running high-volume steel component turning where consistent chip control and coating durability are required. Licensed machinists and CNC operators working in job shop or production environments are the typical end users.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for extended wear resistance on steel and cast iron\u003c\/li\u003e\n  \u003cli\u003ePF chip breaker geometry optimized for finishing and light-to-medium cuts\u003c\/li\u003e\n  \u003cli\u003e55-degree diamond insert shape (DNMG) with neutral hand for versatile setup\u003c\/li\u003e\n  \u003cli\u003eFour usable cutting edges per insert for reduced cost-per-edge\u003c\/li\u003e\n  \u003cli\u003e0.40 mm (0.0156 inch) corner radius for controlled surface finish\u003c\/li\u003e\n  \u003cli\u003eClamp and screw holding compatibility for broad toolholder fitment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in DNMG-style toolholders with a 0.5000-inch inscribed circle seating.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torque wrench and insert screw specified by the toolholder manufacturer when using screw-lock holders — do not overtighten by feel alone. Inspect the insert pocket and seating surface for debris or wear before seating a new cutting edge.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: DNMG 15 04 04-PF 4415\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: DNMG\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\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\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: PF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inches (12.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches (4.76 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2030 inches (5.16 mm)\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\u003c\/strong\u003e: 0 degrees\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: N\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: 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\u003eWeight\u003c\/strong\u003e: 0.03 pounds\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: 7859060\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51747421585714,"sku":"7859060","price":350.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/be52c1c57882b3cd5a14a16883b8ea39_bd04b92e-b9c1-4fb3-95bc-c6c7b3bd605a.jpg?v=1788879853","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7859060-turning-insert-dnmg431-pf-4415","provider":"Voomi Supply","version":"1.0","type":"link"}
