It carries manufacturer grade 4415 and features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which provides thermal resistance and wear protection across a wide range of cutting speeds. The insert has an 80-degree diamond shape (C-type), a neutral hand orientation, a 1.19 mm corner radius, and a 0.5-inch inscribed circle. It is held in place by clamp or screw, depending on the toolholder. Licensed machinists and CNC turning technicians are the primary users of this insert.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered primarily for machining steel (ISO material code P) and secondarily for cast iron (ISO material code K). It fits into T-Max P series toolholders sized for CNMG 12 04 12 geometry. Typical applications include roughing and semi-finishing passes on carbon steel, alloy steel, and gray cast iron components in production turning environments, both in shop and job-shop settings. ISO code for this insert is CNMG 12 04 12-PF 4415. The PF chip breaker geometry is optimized for controlled chip formation at light to medium feed rates.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for extended tool life in steel and cast iron turning\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape with 4 usable cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003e1.19 mm corner radius for balanced surface finish and edge strength\u003c\/li\u003e\n  \u003cli\u003ePF chip breaker geometry for predictable chip control at light to medium feeds\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation compatible with standard CNMG toolholders\u003c\/li\u003e\n  \u003cli\u003eClamp and screw holding method for rigid, repeatable seating in T-Max P holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in T-Max P series CNMG 12 04 12 toolholders.

Inspect the toolholder seat and clamp components for debris or wear before seating the insert. Use the appropriate torque wrench and manufacturer-specified seating procedure for the clamp or screw style holder to avoid insert rocking or premature edge failure. Do not exceed the insert thickness seating depth or attempt to re-grind this indexable insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNMG 12 04 12-PF 4415\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (80 degrees, C-type)\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1.19 mm (0.0469 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: 3\/16 inches (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\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: PF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\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\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 0.43 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 1.54 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 3.74 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 7859047\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51754931028274,"sku":"7859047","price":257.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ea98c3751e8fce5f3b86e0fc4420a04b_135b6813-2046-4074-b5e0-300a97a510d8.jpg?v=1788949892","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7859047-turning-insert-cnmg433-pf-4415","provider":"Voomi Supply","version":"1.0","type":"link"}
