This single-sided, right-hand insert features a rectangular shape with a 90-degree included angle, a positive 30-degree rake angle, and a chamfered and honed cutting edge style. It measures 0.5000 inches in length, 0.3750 inches wide, and 0.1575 inches thick, with a 0.0118-inch corner radius. The TiAlN coating is applied via PVD process, delivering elevated heat resistance and wear performance. Four cutting edges are available per insert, making it an efficient choice for production milling operations. The insert is held in the cutter body by a screw-clamp method and is compatible with the LN cutter series.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered for milling steel, stainless steel, superalloys, and titanium workpieces, corresponding to ISO material groups P, M, and S. It suits applications where controlled chip formation and edge stability are critical, such as face milling, shoulder milling, and high-feed operations on ferrous and difficult-to-machine alloys in both general production and aerospace environments. The GP chip breaker geometry supports consistent chip control across a range of depths of cut and feed rates. Licensed machinists, tooling specialists, and CNC operators working in metalworking shops will find this insert sized for the LNEU insert series toolholders with a 3\/8-inch inscribed circle.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with TiAlN PVD coating for heat and wear resistance in demanding cuts\u003c\/li\u003e\n  \u003cli\u003eFour usable cutting edges per insert for extended tooling economy\u003c\/li\u003e\n  \u003cli\u003e30-degree positive rake angle reduces cutting forces on steel and superalloy workpieces\u003c\/li\u003e\n  \u003cli\u003eGP chip breaker geometry for consistent chip control at moderate to high feed rates\u003c\/li\u003e\n  \u003cli\u003eChamfered and honed cutting edge preparation for edge stability and reduced chipping\u003c\/li\u003e\n  \u003cli\u003eRight-hand orientation with screw-clamp holding method for secure seating in LN-series bodies\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO dimensional standards under designation LNEU1240R03SGP 4\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in LN-series milling cutter bodies that accept LNEU-style inserts with a 3\/8-inch inscribed circle.

Always power down and lock out the machine spindle before seating or indexing inserts. Use the appropriate torx or hex key at the manufacturer-specified procedure to secure the clamping screw without over-torquing the insert pocket. Inspect the insert pocket and clamping screw for wear or debris before installing a new insert to ensure proper seating and edge repeatability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: LNEU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI\/ISO Code\u003c\/strong\u003e: LNEU1240R03SGP 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC725M\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: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\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\u003eSided\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 30 degrees\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\u003eCutting Edge Style\u003c\/strong\u003e: Chamfered and Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: GP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.3750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1575 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.3750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0118 inches (0.30 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\u003eInsert Size Code\u003c\/strong\u003e: 1240\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5, C6, C7\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\u003eCutter Series Compatibility\u003c\/strong\u003e: LN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0128 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: 4058551\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743891128626,"sku":"4058551","price":283.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cbe7633b769d858ff131bcc21e12e5e9.jpg?v=1788850907","url":"https:\/\/voomisupply.com\/products\/kennametal-4058551-milling-insert-kc725m-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
