It belongs to the HELITANG series and is engineered for indexable face and shoulder milling operations. The insert features a butterfly (LNHT) shape with a helical cutting edge style and a negative rake geometry. Applied with an AlTiN plus TiN dual-layer coating via PVD process under ISCAR Sumotec classification, the IC830 grade is formulated for wear resistance and thermal stability in demanding cutting conditions. The insert delivers four usable cutting edges on a double-sided body, making it a cost-effective option for high-volume machining environments where insert life directly affects cycle economics.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for milling steel, stainless steel, superalloys, and titanium alloys, covering ISO material groups P, M, and S. It is intended for use by machinists and CNC tooling specialists in job shops, aerospace component machining, and general metalworking facilities running shoulder or helical milling toolpaths. The insert seats into T490 LNK08 series cutter bodies and is secured by a screw-holding method. Maximum depth of cut reaches 0.3150 inches (8.00 mm), making it applicable for moderate-to-aggressive roughing and semi-finishing passes on difficult-to-machine materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIC830 grade solid carbide with AlTiN plus TiN PVD Sumotec coating for thermal and wear resistance\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges on a double-sided insert body for extended tool economy\u003c\/li\u003e\n  \u003cli\u003eHelical cutting edge style with negative rake reduces shock loading on the cutter body\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.0157 inches (1\/64 inch, 0.40 mm) suits tight-radius shoulder profiling\u003c\/li\u003e\n  \u003cli\u003ePNR chip breaker geometry designed for steel, stainless steel, superalloys, and titanium\u003c\/li\u003e\n  \u003cli\u003eCompliant with ANSI and ISO 13399 insert identification standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with T490 LNK08 series cutter bodies.

Ensure the spindle is fully stopped and the machine is locked out before indexing or replacing inserts. Seat the insert firmly against the pocket locating surfaces before tightening the clamping screw to avoid insert rocking or chatter. Inspect the pocket seating surface for chips or debris prior to installing a fresh edge, as contamination will affect insert position and surface finish.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: T490 LNHT 080404PNR IC830\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: T490 LNHT 080404PNR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HELITANG\u003c\/li\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\u003eInsert Size Code\u003c\/strong\u003e: 080404\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC830\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN plus TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD (Sumotec)\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\u003eCutting Edge Style\u003c\/strong\u003e: Helical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: PNR\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\u003eInscribed Circle\u003c\/strong\u003e: 0.1670 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\u003eThickness\u003c\/strong\u003e: 0.2960 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.1670 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.3150 inches (8.00 mm)\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\u003eMaterial Application Code\u003c\/strong\u003e: P, M, S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: T490 LNK08\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO 13399\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291601\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 5605887\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51729630396722,"sku":"5605887","price":434.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6ee416d7cf74004d05c71dc0f07ac2b9.jpg?v=1788706953","url":"https:\/\/voomisupply.com\/products\/iscar-5605887-milling-insert-t490-lnht-080404pnr-ic830","provider":"Voomi Supply","version":"1.0","type":"link"}
