It features a butterfly (LNMT) insert shape with a negative rake angle, a 90-degree included angle, and a helical cutting edge style that promotes smooth chip flow and reduced cutting forces. The IC330 grade is a PVD-applied TiCN plus TiN coating on a solid carbide substrate, optimized for demanding cutting applications. With four usable cutting edges on a double-sided body, this insert delivers extended tool life per unit. Thickness is 0.514 inches and inscribed circle diameter is 0.262 inches.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for milling steel, stainless steel, superalloys, and titanium in both roughing and finishing operations where helical cutting geometry provides a performance advantage. It is held in the cutter pocket by a screw-clamp method, consistent with HELITANG tooling system practice. The PNTR chip breaker geometry is selected for these workpiece material groups, making the insert applicable across a range of industrial machining environments including aerospace, energy, and general precision metalworking. It is a right-hand cut insert and conforms to both ANSI and ISO 13399 standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIC330 grade: PVD-coated TiCN plus TiN on solid carbide substrate for steel, stainless steel, superalloys, and titanium\u003c\/li\u003e\n  \u003cli\u003e4 cutting edges on a double-sided insert body for reduced tooling cost per edge\u003c\/li\u003e\n  \u003cli\u003eHelical cutting edge style reduces cutting forces and improves surface finish\u003c\/li\u003e\n  \u003cli\u003ePNTR chip breaker geometry suited for the P, M, and S workpiece material classes\u003c\/li\u003e\n  \u003cli\u003eNegative rake, 90-degree included angle for stable, rigid cutting action\u003c\/li\u003e\n  \u003cli\u003eScrew-held mounting method compatible with T490 LNK13 cutter bodies\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and ISO 13399 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with T490 LNK13 series cutter bodies.

Index or replace inserts only after the spindle is fully stopped and the machine is locked out per applicable shop safety procedures. Use the correct torx or hex key to the cutter body manufacturer's specified seating procedure — do not overtighten, as this can fracture the carbide insert. Inspect the pocket seat and clamp screw for wear or damage before seating a 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\u003eInsert Size Code\u003c\/strong\u003e: 1306\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC330\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: TiCN plus TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Helical\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\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\u003eChip Breaker\u003c\/strong\u003e: PNTR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.514 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle Diameter\u003c\/strong\u003e: 0.262 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 (0.79 mm)\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 Materials\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application Codes\u003c\/strong\u003e: P, M, S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: T490 LNK13\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\u003eANSI Code\u003c\/strong\u003e: T490 LNMT 1306PNTR IC330\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: T490 LNMT 1306PNTR\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: 0.04 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: 5606369\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51746436677938,"sku":"5606369","price":370.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/19722e448b00f3880e6a2feb5b65f4db.jpg?v=1788870188","url":"https:\/\/voomisupply.com\/products\/iscar-5606369-milling-insert-t490-lnmt-1306pntr-ic330","provider":"Voomi Supply","version":"1.0","type":"link"}
