It carries the ISO designation LFEW220432ERLN and is manufactured to the KC725M grade with a multilayer PVD coating of TiN, TiCN, and TiN applied in that sequence. The insert measures 0.6252 inches wide and 0.1875 inches thick, with a corner radius of 0.1260 inches and an inscribed circle of 0.3750 inches. The rectangular shape, 25-degree relief angle, and LN chip breaker geometry make it well suited for finishing and semi-finishing passes where edge stability and surface quality are priorities. Installation is by screw-holding method, right-hand orientation.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for machining steel, stainless steel, superalloys, and titanium, corresponding to ISO material codes P, M, and S. It fits milling toolholders designed for the LFEW insert series with a size code of 3538. Typical applications include face milling, shoulder milling, and contour milling on CNC machining centers in both job-shop and production environments. The KC725M grade and PVD coating combination provides wear resistance and thermal stability at moderate to high cutting speeds on difficult-to-machine alloys. This insert is sold in a minimum order quantity of 5 units, with individual package quantity of 1.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with KC725M grade for toughness and wear resistance in steel and superalloy milling\u003c\/li\u003e\n  \u003cli\u003eMultilayer PVD coating: TiN, TiCN, TiN for improved edge integrity and thermal protection\u003c\/li\u003e\n  \u003cli\u003eLN chip breaker geometry optimized for finishing and semi-finishing cuts\u003c\/li\u003e\n  \u003cli\u003e25-degree relief angle reduces cutting forces on difficult workpiece materials\u003c\/li\u003e\n  \u003cli\u003eRight-hand, screw-held mounting for secure insert clamping in LFEW-series toolholders\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.1260 inches (3.20 mm) balances surface finish quality with edge strength\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in milling toolholders and cutter bodies configured for LFEW-series inserts with insert size code 3538.

Power down and lock out the machine spindle before seating or removing inserts. Use the appropriate torx or hex key driver to tighten the clamping screw to the toolholder manufacturer's specified torque; do not overtighten, as this can crack the carbide body. Inspect the insert pocket and seating surfaces for chips or debris before installation to ensure proper insert orientation and full seating.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: LFEW220432ERLN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC725M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Series\u003c\/strong\u003e: LFEW\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Rectangle\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: TiN, TiCN, TiN (PVD Process)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.6252 inches (5\/8 inch nominal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1875 inches (3\/16 inch nominal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness Range\u003c\/strong\u003e: 0.1850 to 0.2000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.8650 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Range\u003c\/strong\u003e: 0.7000 to 0.9000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.3750 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.1260 inches (3.20 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2165 inches (0.22 mm seat)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 25 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake 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\u003eChip Breaker\u003c\/strong\u003e: LN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 3538\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5, C6, C7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Material Code\u003c\/strong\u003e: P, M, S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291601\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0331 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 1184136\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743884575026,"sku":"1184136","price":371.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/291253285221d6f2d0854e4aa376ae5d.jpg?v=1788850755","url":"https:\/\/voomisupply.com\/products\/kennametal-1184136-milling-insert-kc725m-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
