It belongs to the HELITANG series and is designed for face and shoulder milling operations where consistent chip control and edge integrity are critical. The insert features a butterfly (LNMT) shape with a helical cutting edge style, a negative rake angle, and a 90-degree included angle. CVD-applied TiCN and Al2O3 coating layers provide wear resistance and thermal stability. With four usable cutting edges and a double-sided configuration, it delivers extended tool life per insert. Maximum depth of cut reaches 0.492 inches. Licensed machinists and CNC operators working in production environments are the primary installers of this insert.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for milling cast iron workpieces, corresponding to ISO material application code K. It is engineered for use in the T490 LNK13 cutter series. Typical applications include roughing and semi-finishing passes on cast iron components in metalworking, automotive, and general machining operations. The screw-holding method ensures secure seating in compatible toolholders. Right-hand cutting orientation must be confirmed against the toolholder specification before installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with CVD TiCN and Al2O3 multilayer coating for cast iron machining\u003c\/li\u003e\n  \u003cli\u003eButterfly (LNMT) insert shape with helical cutting edge style for smooth chip flow\u003c\/li\u003e\n  \u003cli\u003eDouble-sided insert with 4 cutting edges for maximum yield per insert\u003c\/li\u003e\n  \u003cli\u003eNegative rake, 0-degree relief angle, 90-degree included angle geometry\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut: 0.492 inches (12.50 mm)\u003c\/li\u003e\n  \u003cli\u003ePNTR chip breaker geometry optimized for cast iron applications\u003c\/li\u003e\n  \u003cli\u003eCompliant with ANSI and ISO 13399 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the ISCAR T490 LNK13 cutter series.

Ensure the machine spindle is fully stopped and locked out before accessing the cutter body. Use the correct torx or hex key to the toolholder manufacturer's specified seating procedure to avoid insert rocking or premature edge failure. Verify right-hand cutting direction and confirm insert pocket is free of chips and debris before seating the new insert.\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\u003eANSI Code\u003c\/strong\u003e: T490 LNMT 1306PNTR IC5100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: T490 LNMT 1306PNTR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC5100\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 and Al2O3 (CVD process)\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\u003eInsert Size Code\u003c\/strong\u003e: 1306\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.262 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.514 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Effective Length\u003c\/strong\u003e: 0.5409 inches\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\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.492 inches (12.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron (ISO Code K)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: PNTR\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\u003eCutter Series Compatibility\u003c\/strong\u003e: T490 LNK13\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: 0.27 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: 5605883\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51728591814962,"sku":"5605883","price":369.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7c8b21b6bc0445a77435eaa719a6fed3.jpg?v=1788693732","url":"https:\/\/voomisupply.com\/products\/iscar-5605883-milling-insert-t490-lnmt-1306pntr-ic5100","provider":"Voomi Supply","version":"1.0","type":"link"}
