It carries the ISO designation LFEW150316ERLN and is manufactured to the KC725M grade, featuring a multilayer PVD coating of TiN, TiCN, and TiN. This coating sequence improves wear resistance and thermal stability during interrupted cuts and high-feed applications. The insert measures 0.6217 inches in length, 0.3752 inches in width, and 0.1299 inches in thickness, with a 0.0630-inch corner radius. It is a right-hand configuration with a screw-in holding method. Machinists and CNC operators working in steel, stainless steel, and superalloy applications will find this insert suited for production milling work.\u003c\/p\u003e\n\u003cp\u003eThis insert is applied in milling operations targeting steel, stainless steel, superalloys, and titanium workpiece materials, corresponding to ISO material codes P, M, and S. It is appropriate for use on CNC machining centers in both roughing and semi-finishing passes where consistent tool life and edge integrity are required. The LN chip breaker geometry helps manage chip flow and reduce cutting forces at the edge. The 90-degree included angle and rectangular insert shape make it a fit for square-shoulder and face milling toolholders that accept LFEW-series inserts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKC725M grade with multilayer PVD coating: TiN outer, TiCN mid, TiN base for enhanced wear resistance\u003c\/li\u003e\n  \u003cli\u003eLN chip breaker geometry for controlled chip evacuation and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003e0.0630-inch corner radius (1.60 mm) for edge strength and surface finish consistency\u003c\/li\u003e\n  \u003cli\u003eRight-hand orientation with screw-in holding method for secure seating in the toolholder pocket\u003c\/li\u003e\n  \u003cli\u003eRated for P, M, and S workpiece material classifications covering steel, stainless steel, superalloys, and titanium\u003c\/li\u003e\n  \u003cli\u003e25-degree relief angle and 0-degree rake angle for stable, predictable cutting geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in LFEW-series milling toolholders that accept LFEW150316 inserts with screw-in mounting.

Always bring the spindle to a full stop and lock out the machine before changing inserts. Seat the insert fully in the pocket and torque the clamping screw to the toolholder manufacturer specification using the correct Torx or hex key. Inspect the pocket seat and shim for wear or debris before installing a fresh insert, as a contaminated pocket will cause premature edge failure or insert breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: LFEW150316ERLN\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\u003eLength\u003c\/strong\u003e: 0.6217 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.3752 inches (3\/8 inch nominal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1299 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0630 inches (1\/16 inch nominal, 1.60 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inches\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: 2524\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\u003eUNSPSC Code\u003c\/strong\u003e: 23291601\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.011 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 per package (minimum order quantity: 5)\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: 1184129\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51731978060082,"sku":"1184129","price":357.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/742845ac94608cb7dbefdefdb191186b.jpg?v=1788737522","url":"https:\/\/voomisupply.com\/products\/kennametal-1184129-milling-insert-lfew150316erln-kc725m","provider":"Voomi Supply","version":"1.0","type":"link"}
