The insert carries a dual PVD coating of TiAlN and AlCrN, which extends tool life when cutting steel, stainless steel, superalloys, and titanium. It measures 0.274 inches thick and 0.394 inches in inscribed circle diameter, with a rectangular LNGU shape and a 90-degree included angle. Four cutting edges and a positive rake geometry reduce cutting forces and heat generation at the tool-workpiece interface. The honed cutting edge style and GE chip breaker geometry support controlled chip evacuation. Installed by machinists and CNC tooling technicians, this insert fits screw-type clamping systems.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for milling operations on steel, stainless steel, superalloys, and titanium in both production and job-shop environments. It is compatible with the Kennametal Mill 4-15 cutter series. The right-hand configuration and LNGU insert style make it a direct fit for toolholders specifying ANSI code LNGU542ERGE or ISO code LNGU15T608ERGE. Applications include face milling, shoulder milling, and general-purpose milling where consistent surface finish and edge integrity are required across difficult-to-machine workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with dual PVD coating: TiAlN and AlCrN for thermal and wear resistance\u003c\/li\u003e\n  \u003cli\u003e4 cutting edges on a single-sided rectangular LNGU insert for cost-effective use\u003c\/li\u003e\n  \u003cli\u003eGE chip breaker geometry with positive rake for reduced cutting forces on steel and superalloys\u003c\/li\u003e\n  \u003cli\u003eHoned cutting edge style for improved edge toughness and consistent engagement\u003c\/li\u003e\n  \u003cli\u003eScrew-type insert holding for secure clamping in compatible milling bodies\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and ISO standards: LNGU542ERGE and LNGU15T608ERGE respectively\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the Kennametal Mill 4-15 cutter series. Compatible toolholders must accept ANSI insert code LNGU542ERGE or ISO insert code LNGU15T608ERGE with screw-type clamping. Primary workpiece materials are steel (P), stainless steel (M), superalloys, and titanium (S).\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before changing inserts. Use the correct torx or hex key specified for the cutter body to seat the screw clamp to the manufacturer torque specification found in the cutter body documentation. Inspect the insert pocket and seating surface for chips or debris before seating a new insert, as contamination can cause edge failure or insert breakage during cutting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Grade\u003c\/strong\u003e: KCPM40\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: TiAlN and AlCrN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Rectangle (LNGU)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: LNGU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: LNGU542ERGE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: LNGU15T608ERGE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 542\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.274 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle Diameter\u003c\/strong\u003e: 0.394 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.670 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.031 inches (1\/32 inch, 0.80 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1831 inches (0.18 mm nominal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: GE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\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 Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double Sided\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\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\u003eCutter Series Compatibility\u003c\/strong\u003e: Mill 4-15\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5588387\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51747799957810,"sku":"5588387","price":591.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b23fc90fd46f8b4218a5953042cdb7b8_b60a9b3f-d277-4c59-99bf-b92bd001f090.jpg?v=1788885626","url":"https:\/\/voomisupply.com\/products\/kennametal-5588387-kcpm40-milling-insert-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
