Designed for use in helical-edge face and shoulder milling cutters, this insert features a butterfly (LNMT) shape with a negative rake geometry and a 90-degree included angle. It is double-sided, providing 4 usable cutting edges per insert. The IC830 grade is finished with an AlTiN plus TiN PVD coating classified under ISCAR Sumotec PVD, making it well-suited for demanding cuts in steel, stainless steel, and superalloys including titanium. The insert is held in the cutter body by a screw and is installed by machinists and tooling technicians on CNC milling equipment.\u003c\/p\u003e\u003cp\u003eThis insert is intended for milling applications in steel, stainless steel, superalloys, and titanium workpieces in both production and job-shop environments. The helical cutting edge style reduces cutting forces and aids chip evacuation, which is especially valuable in interrupted cuts and high-feed operations on difficult-to-machine materials. The PNR chip breaker geometry supports stable cutting across a range of depths and feed rates up to a maximum depth of cut of 0.3150 inches (8.00 mm). Right-hand cutting orientation is standard for this insert.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDouble-sided LNMT butterfly insert with 4 cutting edges for extended tool life per insert\u003c\/li\u003e\n\u003cli\u003eIC830 grade with AlTiN plus TiN Sumotec PVD coating for high wear resistance in steel and superalloys\u003c\/li\u003e\n\u003cli\u003eHelical cutting edge style reduces cutting forces and improves chip flow\u003c\/li\u003e\n\u003cli\u003ePNR chip breaker optimized for steel, stainless steel, and titanium applications\u003c\/li\u003e\n\u003cli\u003eNegative rake, 0-degree relief angle for strong cutting edge and screw-lock retention\u003c\/li\u003e\n\u003cli\u003eCompliant with ANSI and ISO 13399 insert standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eThis insert is compatible with the ISCAR T490 LNK08 cutter series as specified by the manufacturer.

Power down and lock out the machine spindle before seating or removing inserts. Use the correct torx or hex key as specified by the cutter body manufacturer when tightening the retaining screw — do not overtighten. Inspect the insert pocket and seating surface for chips or debris before installing a new insert to ensure proper seating and edge alignment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eInsert Size Code\u003c\/strong\u003e: 0804\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC830\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 PVD)\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\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\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\u003eCorner Radius\u003c\/strong\u003e: 0.0157 inches (0.40 mm, 1\/64 inch)\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 Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HELITANG\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 Material\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: T490 LNMT 0804PNR IC830\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: T490 LNMT 0804PNR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO 13399\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0125 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 5606105\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51739014758706,"sku":"5606105","price":346.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b376450634f23806ce6ac116e8d8af9b.jpg?v=1788808005","url":"https:\/\/voomisupply.com\/products\/iscar-5606105-t490-lnmt-0804pnr-ic830-milling-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
