The insert features a TiAlN PVD coating applied over solid carbide substrate, delivering wear resistance and thermal stability during high-demand milling operations. With 12 cutting edges, a 0.8750-inch inscribed circle, and a 0.2923-inch thickness, this double-sided, neutral-hand insert maximizes tool life per unit cost. A honed T-Land cutting edge style with a 15-degree rake angle and HD chip breaker geometry makes it well suited for aggressive material removal on difficult-to-machine workpieces. Licensed machinists and tooling specialists install this insert in compatible Dodeka-series milling cutter bodies.\u003c\/p\u003e\n\u003cp\u003eThis insert is designed for milling steel, stainless steel, superalloys, and titanium, corresponding to material grade classifications C5, C6, and C7 (ISO work material codes P, M, and S). It is appropriate for both roughing and finishing passes where positive rake geometry and reliable chip control are required. The maximum depth of cut reaches 0.5052 inches, making it suitable for productive slotting and face milling applications in job shop and production environments. The screw-held mounting method provides secure clamping and repeatable edge indexing during insert changes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e12 cutting edges per insert on a double-sided hexagon geometry, lowering cost per edge\u003c\/li\u003e\n  \u003cli\u003eTiAlN PVD coating for elevated thermal resistance and extended tool life on steel and superalloys\u003c\/li\u003e\n  \u003cli\u003eHD chip breaker with honed T-Land edge for controlled chip formation and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003e15-degree positive rake angle minimizes cutting forces on difficult workpiece materials\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.5052 inches supports both roughing and semi-finishing operations\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI code HNPJ755ANSNHD and ISO code HNPJ130720ANSNHD for standardized tooling specification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in KENNAMETAL Dodeka-series milling cutter bodies.

Ensure the cutter body is removed from the spindle and all machine motion is stopped before indexing or replacing inserts. Use the appropriate torx or hex key to the cutter body manufacturer's specified seating procedure when fastening the mounting screw, and verify the insert seats flush against all pocket surfaces before returning the tool to service. Follow the cutter body manufacturer's guidelines for insert orientation and torque sequence.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: HNPJ\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: HNPJ130720ANSNHD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: HNPJ755ANSNHD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Hexagon\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: KC725M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSided\u003c\/strong\u003e: Double\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 15 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0.00 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 120 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: HD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed T-Land\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.8750 inches (7\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.8750 inches (7\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.8750 inches (7\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.2923 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0787 inches (2.00 mm, 5\/64 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.3150 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.5052 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 755\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5, C6, C7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: Dodeka\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.031 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 per package, minimum order quantity 5\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: 4057830\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51750695207218,"sku":"4057830","price":324.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a6928d11e5c1e33557092459bb1776fb.jpg?v=1788918578","url":"https:\/\/voomisupply.com\/products\/kennametal-4057830-milling-insert-hnpj130720ansnhd-kc725m","provider":"Voomi Supply","version":"1.0","type":"link"}
