Coated with AlTiN via a PVD process, this insert provides heat resistance and wear protection at the cutting edge. It carries a KC522M manufacturer grade and features a GE chip breaker geometry with a chamfered and honed cutting edge style. Four cutting edges are available per insert, and the right-hand configuration suits standard LNGU toolholder setups. The positive rake angle and 0-degree relief angle are suited for high-efficiency face and shoulder milling on a range of workpiece materials.\u003c\/p\u003e\u003cp\u003eThis insert is appropriate for milling steel, stainless steel, cast iron, superalloys, and titanium, corresponding to ISO material groups P, M, K, and S. It is compatible with the Mill 4-15 cutter series and is held in place by a screw clamping method. Typical applications include production milling in job shops and manufacturing facilities where consistent tool performance across multiple workpiece materials is required. Licensed machinists and CNC operators are the primary installers and users of this insert.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiN coating applied via PVD process for improved heat and wear resistance\u003c\/li\u003e\n\u003cli\u003e4 cutting edges per insert for extended tool life and cost efficiency\u003c\/li\u003e\n\u003cli\u003eGE chip breaker with chamfered and honed edge for controlled chip formation\u003c\/li\u003e\n\u003cli\u003ePositive rake geometry suited for reduced cutting forces on steel and superalloys\u003c\/li\u003e\n\u003cli\u003eScrew-held LNGU insert style with right-hand orientation\u003c\/li\u003e\n\u003cli\u003eMeets ANSI and ISO standards; ANSI code LNGU542SRGE, ISO code LNGU15T608SRGE\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with the Mill 4-15 cutter series.

Always power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate Torx or hex key to secure the clamping screw to the toolholder specification; do not overtighten. Inspect the insert pocket and clamping screw for wear or debris before seating the new insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: LNGU\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC522M\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: AlTiN\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\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: 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\u003eCorner Radius\u003c\/strong\u003e: 0.0315 inches (0.80 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.3937 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.3937 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.6700 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.2740 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: GE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Chamfered and Honed\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: Mill 4-15\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: LNGU542SRGE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: LNGU15T608SRGE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double Sided\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5515890\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51736670470450,"sku":"5515890","price":555.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d0ef1393c5d2f8be1faa504bbf3a685d_902db0e9-1816-41da-af2c-179a64956219.jpg?v=1788779299","url":"https:\/\/voomisupply.com\/products\/kennametal-5515890-milling-insert-kc522m-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
