Identified by ISO code HNGJ0905ANSNHD and ANSI code HNGJ535ANSNHD, this double-sided hexagon insert delivers 12 usable cutting edges per insert, maximizing tool life and reducing per-edge cost. The TiAlN PVD coating provides thermal resistance and wear protection suited to demanding cutting conditions. With a negative rake angle of 15 degrees and a chamfered and honed cutting edge style, the insert maintains edge integrity under interrupted cuts and high-feed passes. The HD chip breaker geometry promotes controlled chip evacuation in medium to heavy milling applications.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use in Kennametal Dodeka cutter series toolholders. It suits milling operations in aerospace, energy, and general machining environments where the workpiece material is steel, stainless steel, or difficult-to-machine superalloys and titanium alloys. The neutral hand orientation allows use in both conventional and climb milling setups. The screw-holding method provides positive insert location and simplifies indexing during production runs. Typical installations include face milling, shoulder milling, and profile milling on CNC machining centers and horizontal mills.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e12 cutting edges per double-sided hexagon insert for low cost per edge\u003c\/li\u003e\n  \u003cli\u003eTiAlN PVD coating for high-temperature wear resistance on steel and superalloys\u003c\/li\u003e\n  \u003cli\u003eHD chip breaker geometry for controlled chip formation in medium to heavy cuts\u003c\/li\u003e\n  \u003cli\u003eNegative rake with chamfered and honed edge for edge strength under load\u003c\/li\u003e\n  \u003cli\u003eCompatible with Kennametal Dodeka cutter series via screw-clamp holding\u003c\/li\u003e\n  \u003cli\u003eNeutral hand design suits both climb and conventional milling orientations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in the Kennametal Dodeka cutter series.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate Torx or hex key for the insert clamping screw as specified in the Dodeka cutter toolholder documentation. Inspect the insert pocket seat and screw threads for debris or damage before seating a new insert to ensure proper location and clamping force.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: HNGJ0905ANSNHD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: HNGJ535ANSNHD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: HNGJ\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Hexagon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC725M\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: 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\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\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 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: Chamfered and Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSided\u003c\/strong\u003e: Double\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0472 inches (1.20 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.215 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.35 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys, Titanium\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\u003eMaterial Grade\u003c\/strong\u003e: C5, C6, C7\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: 3556331\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732748665138,"sku":"3556331","price":284.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6915773e5f85e2f8d40cc6b1b6c0a2c6.jpg?v=1788746273","url":"https:\/\/voomisupply.com\/products\/kennametal-3556331-milling-insert-hngj0905ansnhd-kc725m","provider":"Voomi Supply","version":"1.0","type":"link"}
