This double-sided, negative-rake insert features a butterfly (LNMT) shape with four cutting edges, extending tool life between changeovers. The IC830 grade substrate carries a multilayer PVD coating — TiAlN, AlTiN, and TiN — applied using Sumotec PVD technology for thermal resistance and edge wear protection. At 0.623 inches thick with a 0.276-inch inscribed circle and a 1\/32-inch corner radius, the insert fits T490 LNK16 series milling bodies and is held in place by a screw-lock method. It is suited for CNC machining centers running moderate to aggressive cutting parameters.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use in industrial CNC milling applications across a broad range of primary workpiece materials including steel, stainless steel, cast iron, superalloys, titanium, and hard materials (ISO material codes P, M, K, S, H). The helical cutting edge style and R-type chip breaker geometry promote controlled chip evacuation in both roughing and semi-finishing passes. Maximum depth of cut reaches 0.630 inches (16.00 mm). The right-hand cutting orientation must be matched to the intended cutter body configuration. This insert is specified per ANSI and ISO 13399 standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble-sided insert with 4 cutting edges for extended tool life\u003c\/li\u003e\n  \u003cli\u003eSumotec PVD multilayer coating (TiAlN \/ AlTiN \/ TiN) for heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003eHelical cutting edge with R-type chip breaker for controlled chip flow\u003c\/li\u003e\n  \u003cli\u003eNegative rake, 90-degree included angle geometry for stable shoulder milling\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut 0.630 inches (16.00 mm)\u003c\/li\u003e\n  \u003cli\u003eScrew-lock insert holding for secure seating under high cutting forces\u003c\/li\u003e\n  \u003cli\u003eSubmicron carbide grain structure for consistent edge integrity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with T490 LNK16 series milling cutter bodies.

Power down and lock out the spindle before seating or removing inserts. Use the correct torque driver for the screw-lock fastener — refer to the cutter body manufacturer specifications for the applicable seating torque. Inspect the pocket seat for chips or debris before installing a new insert, as contaminated seats cause premature edge failure.\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 Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: IC830\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN \/ AlTiN \/ 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\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: 1607\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.276 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.623 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Effective Length\u003c\/strong\u003e: 0.6713 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0315 inches (0.79 mm \/ 1\/32 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.630 inches (16.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: R\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\u003eSingle or Double Sided\u003c\/strong\u003e: Double\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys and Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Material Codes\u003c\/strong\u003e: P, M, K, S, H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: T490 LNK16\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: 0.01 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: 5606093\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51734262153522,"sku":"5606093","price":405.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7269859e52294cdb9618b0d30b6423eb.jpg?v=1788761710","url":"https:\/\/voomisupply.com\/products\/iscar-5606093-milling-insert-t490-lnmt-1607pn-r-ic830","provider":"Voomi Supply","version":"1.0","type":"link"}
