It features an 80-degree diamond (rhombic) insert shape with a 5\/8 inch inscribed circle and a 1\/16 inch corner radius. The insert carries a CVD-applied Al2O3\/TiCN multilayer coating under the proprietary Super FF designation, providing thermal resistance and extended tool life on K-grade workpiece materials. Insert thickness is 0.25 inches with a flat top chip breaker geometry and negative rake and side clearance. This insert is used by CNC machinists and toolroom operators running turning centers and engine lathes.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for external and internal turning operations on cast iron workpieces in production and job-shop environments. The AC4015K grade is positioned for K15 material applications, targeting conditions that range from high-wear to moderate-wear with acceptable toughness. The flat top chip breaker and negative rake geometry are well matched to interrupted and semi-continuous cuts typical in cast iron turning. It is held in the toolholder by pin or screw clamping methods compatible with CNMA-style pockets.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAC4015K grade carbide with CVD Al2O3\/TiCN multilayer coating for cast iron turning\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond (C-shape) insert geometry with negative rake and negative side clearance\u003c\/li\u003e\n  \u003cli\u003e5\/8 inch (0.6250 inch) inscribed circle for standard CNMA toolholder pockets\u003c\/li\u003e\n  \u003cli\u003e1\/16 inch corner radius for general-purpose finish and semi-finish turning\u003c\/li\u003e\n  \u003cli\u003eFlat top chip breaker supports consistent chip control on K-grade materials\u003c\/li\u003e\n  \u003cli\u003eCompatible with pin and screw clamping insert holding methods\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNMA-style toolholders accepting a 544 ANSI size code insert (ISO size code 160616).

The machine spindle must be stopped and the toolholder fully de-energized before seating or removing the insert. Ensure the toolholder pocket is clean and free of chips or debris before clamping to maintain accurate insert seating. Torque the clamping screw or pin to the toolholder manufacturer specification; do not exceed the recommended clamping force to avoid insert fracture.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CNMA544\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CNMA160616\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: AC4015K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: K15\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Al2O3\/TiCN (CVD), Super FF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: C - Diamond (Rhombic) 80 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 5\/8 inch (0.6250 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/4 inch (0.6339 inch decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length (Decimal)\u003c\/strong\u003e: 0.6339 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 6.35 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: Flat Top\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees (Negative Rake)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Pin, Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron (K)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO 13399\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.5 x 1.5 x 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eItem Package Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: SUMITOMO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 19T2226\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51727973548338,"sku":"19T2226","price":297.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fe242bfd9d1ee4bd36d9836f60cbdf26.jpg?v=1788685172","url":"https:\/\/voomisupply.com\/products\/sumitomo-19t2226-carbide-turning-insert-cnma544-ac4015k","provider":"Voomi Supply","version":"1.0","type":"link"}
