It features a butterfly (LNMT) insert shape with a helical cutting edge style and a negative rake geometry, giving it four usable cutting edges per insert. The IC830 grade uses a Sumotec PVD-applied AlTiN plus TiN coating for thermal resistance and wear performance when cutting ferrous and difficult-to-machine materials. The insert measures 0.3382 inches in effective cutting edge length and 0.2930 inches thick, with a corner radius of 0.0315 inches (1\/32 inch). It is held in the cutter body by a screw-clamp method and is designed for right-hand cutting direction.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for milling steel, stainless steel, superalloys, and titanium alloys in both roughing and finishing applications. It belongs to the HELITANG series and is compatible with T490 LNK08 cutter bodies. The PNR chip breaker geometry supports controlled chip formation across a range of depths of cut up to 0.3150 inches (8.00 mm). Typical applications include shoulder milling, slot milling, and ramping in aerospace, energy, and general machining environments where tool life on tough materials is a priority. Licensed machinists and CNC tooling specialists are the primary installers and end users.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIC830 grade with Sumotec PVD AlTiN plus TiN coating for heat and wear resistance on steel and superalloys\u003c\/li\u003e\n  \u003cli\u003eDouble-sided insert with 4 cutting edges per insert for extended insert economy\u003c\/li\u003e\n  \u003cli\u003eHelical cutting edge style reduces cutting forces and vibration during milling\u003c\/li\u003e\n  \u003cli\u003eNegative rake, 0-degree relief angle geometry provides strong cutting edge for interrupted cuts\u003c\/li\u003e\n  \u003cli\u003ePNR chip breaker optimized for steel, stainless steel, superalloys, and titanium\u003c\/li\u003e\n  \u003cli\u003eScrew-clamp insert holding method for positive, repeatable seating in the cutter pocket\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with T490 LNK08 series cutter bodies.

Always de-energize and lock out the spindle before changing inserts. Seat the insert fully into the pocket and confirm the screw is snug before resuming cuts. Inspect the pocket seating surface for chips or damage each time the insert is indexed to maintain dimensional accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: LNMT\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\u003eManufacturer Grade\u003c\/strong\u003e: IC830\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\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\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\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\u003eSided\u003c\/strong\u003e: Double\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0315 inches (0.80 mm \/ 1\/32 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.1670 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.2930 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\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.3150 inches (8.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 080408\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\u003eANSI Code\u003c\/strong\u003e: T490 LNMT 080408PNR IC830\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: T490 LNMT 080408PNR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO 13399\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: T490 LNK08\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.071 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: 5607266\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51727907815730,"sku":"5607266","price":355.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ab692bb3970c84634f217a2c52a406c3.jpg?v=1788684347","url":"https:\/\/voomisupply.com\/products\/iscar-5607266-milling-insert-t490-lnmt-080408pnr-ic830-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
