It features a parallelogram shape with an 85-degree included angle, right-hand orientation, and a GD chip breaker geometry suited for interrupted and continuous cuts. The insert is PVD-coated with a TiN\/TiCN\/TiN multilayer finish to balance wear resistance and edge toughness. At 0.2071 inches thick and 0.3713 inches wide, with a 1\/32-inch corner radius and a relief angle of 11 degrees, it is designed for milling operations where edge integrity and thermal stability are critical. Licensed machinists and CNC tool setters are the primary users of this insert.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered for milling steel, stainless steel, superalloys, and titanium, corresponding to ISO material codes P, M, and S. It fits into APPT-series toolholders and is screw-held in place, which provides secure clamping during high-feed or side-milling passes. The maximum depth of cut is 0.2130 inches, making it appropriate for moderate stock removal in both roughing and semi-finishing passes on machining centers and milling machines in production and job-shop environments alike.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eISO designation APPT1604PDERGD with KC725M manufacturer grade for consistent lot-to-lot performance\u003c\/li\u003e\n  \u003cli\u003ePVD-applied TiN\/TiCN\/TiN multilayer coating for improved edge toughness and reduced built-up edge\u003c\/li\u003e\n  \u003cli\u003eGD chip breaker geometry controls chip flow across steel, stainless steel, and superalloy workpieces\u003c\/li\u003e\n  \u003cli\u003eRight-hand insert orientation with screw-hold mounting for positive, repeatable clamping\u003c\/li\u003e\n  \u003cli\u003e1\/32-inch corner radius reduces corner stress while maintaining surface finish quality\u003c\/li\u003e\n  \u003cli\u003eMaterial grades C5, C6, and C7 broaden the usable cutting parameter range across application types\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in APPT-series screw-clamp milling toolholders accepting size 1604 inserts with a right-hand orientation.

Power down and lock out the machine spindle before seating or replacing inserts. Use the correct Torx or hex key to snug the clamping screw without over-torquing, which can fracture the carbide substrate. Inspect the insert pocket and clamping screw threads for wear or contamination before each insert change to ensure full seating and runout control.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: APPT1604PDERGD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC725M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Parallelogram\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: TiN\/TiCN\/TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5, C6, C7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 1604\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 85 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 15 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: GD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.2071 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.3713 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.6787 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0315 inches (0.80 mm, 1\/32 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.2130 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0159 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291601\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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2226320\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51736335614258,"sku":"2226320","price":204.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/346b06ffe40af7f709264aa68832c73a.jpg?v=1788777298","url":"https:\/\/voomisupply.com\/products\/kennametal-2226320-milling-insert-appt1604pdergd-kc725m","provider":"Voomi Supply","version":"1.0","type":"link"}
