This double-sided, octagon-shaped insert features 16 cutting edges and a negative rake geometry, maximizing tool life and cost-per-edge efficiency. The KCK20B grade incorporates a multilayer MTCVD coating system — TiCN, Al2O3, and TiOCN — that delivers wear resistance and thermal stability during interrupted and continuous cuts. Primary workpiece materials are cast iron and steel. The HB chip breaker geometry includes a chamfered and honed cutting edge style suited to stable cutting conditions. Installed by machinists and tooling technicians on CNC milling centers, this insert fits the Mill 16 cutter series.\u003c\/p\u003e\n\u003cp\u003eThis insert is rated for primary use in cast iron (K material code) and secondary use in steel (P material code), covering a broad range of production machining scenarios including automotive, die, and general engineering components. The ONGX series double-sided design allows the insert to be indexed multiple times before replacement, reducing downtime in high-volume milling operations. The neutral hand configuration makes it suitable for both climb and conventional milling setups where the cutter geometry permits. Compatible cutter series is Mill 16, and the insert is held in place by a screw-lock method standard to that platform.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e16 cutting edges per insert — double-sided octagon geometry for maximum indexing value\u003c\/li\u003e\n  \u003cli\u003eMTCVD multilayer coating (TiCN \/ Al2O3 \/ TiOCN) for thermal and abrasion resistance\u003c\/li\u003e\n  \u003cli\u003eKCK20B grade optimized for cast iron and steel milling\u003c\/li\u003e\n  \u003cli\u003eHB chip breaker with chamfered and honed edge for stable, controlled cutting\u003c\/li\u003e\n  \u003cli\u003eNegative rake, 135-degree included angle geometry for rigidity under heavy cuts\u003c\/li\u003e\n  \u003cli\u003eScrew-lock insert holding method compatible with Mill 16 cutter bodies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in the Kennametal Mill 16 cutter series.

Use the appropriate Torx or hex key as specified by the Mill 16 cutter body manufacturer for the insert clamping screw; do not overtighten the screw or use impact tooling. Inspect the insert pocket seat and clamping screw for wear or debris before seating a new insert. Follow the cutter body manufacturer's recommended starting speeds and feeds for the KCK20B grade when machining cast iron or steel.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: ONGX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: ONGX080630SNHB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: ONGX648SNHB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Octagon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCK20B\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: TiCN \/ Al2O3 \/ TiOCN (MTCVD, CVD classification)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 16\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\u003eIncluded Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.1180 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.7870 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.2290 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.7870 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.7870 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.3260 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: HB\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\u003eSingle or Double Sided\u003c\/strong\u003e: Double\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\u003eSecondary Workpiece Material\u003c\/strong\u003e: Steel (P)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: Mill 16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291601\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.27 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 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: 6969278\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51737735627058,"sku":"6969278","price":410.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9d6ae3f2b41f3e1a5352bfbf09dd6e0a.jpg?v=1788792961","url":"https:\/\/voomisupply.com\/products\/kennametal-6969278-milling-insert-ongx080630snhb-kck20b","provider":"Voomi Supply","version":"1.0","type":"link"}
