It belongs to ISCAR's HELITANG series and is designed for use in T490 LNK08 cutter bodies. The butterfly-shaped LNHT insert features a helical cutting edge style, a negative rake angle, and a 90-degree included angle. Four usable cutting edges are available on this double-sided insert. The IC808 grade substrate is submicron carbide with a multilayer PVD coating — TiAlN, AlTiN, and TiN — classified under ISCAR's Sumotec PVD system. This combination delivers thermal resistance and edge stability across demanding milling applications. Installation is performed by machining professionals in shop and field environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for milling steel, stainless steel, cast iron, superalloys, titanium, and hard materials — covering ISO material groups P, M, K, S, and H. It is applied in face milling, shoulder milling, and high-feed profiling operations where consistent edge life across difficult workpiece materials is required. The PNR chip breaker geometry supports controlled chip evacuation in these applications. Right-hand cutting orientation is standard for this insert. Minimum order quantity is 10 pieces per order; package quantity is 1.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIC808 submicron carbide grade with multilayer Sumotec PVD coating (TiAlN, AlTiN, TiN) for extended tool life\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges on a double-sided insert body reduces per-edge tooling cost\u003c\/li\u003e\n  \u003cli\u003eHelical cutting edge style reduces entry shock and cutting forces\u003c\/li\u003e\n  \u003cli\u003ePNR chip breaker geometry supports chip control across steel and hard material applications\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.315 inches (8.00 mm) per pass\u003c\/li\u003e\n  \u003cli\u003eScrew-held mounting for positive insert location in the cutter pocket\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with ISCAR T490 LNK08 series cutter bodies per the manufacturer's stated cutter series compatibility.

The machine spindle must be fully stopped and the machine locked out before indexing or replacing inserts. Inspect the cutter pocket seating surface for debris or damage before seating a new insert, as an unclean pocket will affect runout and edge life. Dispose of worn inserts per applicable shop and local regulations for carbide tooling waste.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: LNHT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Butterfly\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HELITANG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: T490 LNHT 080404PNR IC808\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: T490 LNHT 080404PNR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC808\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN, AlTiN, TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD (Sumotec PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double Sided\u003c\/strong\u003e: Double\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\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: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: PNR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Helical\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: 0.296 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.167 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Effective Length\u003c\/strong\u003e: 0.3382 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0157 inches (1\/64 inch, 0.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.315 inches (8.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: T490 LNK08\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys and Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Material Codes\u003c\/strong\u003e: P, M, K, S, H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO 13399\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: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 pounds\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: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5606320\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51728327573810,"sku":"5606320","price":421.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a6ed5291d6343e19d9596f2ff0ff1940.jpg?v=1788690481","url":"https:\/\/voomisupply.com\/products\/iscar-5606320-milling-insert-t490-lnht-080404pnr-ic808","provider":"Voomi Supply","version":"1.0","type":"link"}
