It carries a KC725M manufacturer grade and features a multilayer PVD coating of TiN, TiCN, and TiN for extended wear resistance and thermal protection. The insert has a square shape with a 90-degree included angle, a neutral hand orientation, and an LN chip breaker geometry. At 0.1874 inches thick with a 0.5000-inch inscribed circle and a corner radius of 0.0449 inches, this insert is engineered for consistent performance in high-demand milling operations. Licensed HVAC and mechanical trades are not the target here — this part is installed by machinists and CNC operators in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is designed for milling steel, stainless steel, superalloys, and titanium, corresponding to ISO material codes P, M, and S. It is well-suited for face milling, shoulder milling, and general-purpose milling applications where workpiece materials demand a durable, heat-resistant cutting edge. The screw-in insert holding method ensures secure clamping in compatible toolholders. It is appropriate for both roughing and finishing passes depending on feed and speed parameters selected by the operator.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with multilayer PVD coating: TiN, TiCN, TiN for wear and heat resistance\u003c\/li\u003e\n  \u003cli\u003eKC725M grade rated for steel, stainless steel, superalloys, and titanium (ISO P, M, S)\u003c\/li\u003e\n  \u003cli\u003eLN chip breaker geometry for controlled chip evacuation\u003c\/li\u003e\n  \u003cli\u003eSquare insert shape with 90-degree included angle and neutral hand\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.0449 inches for edge strength and surface finish control\u003c\/li\u003e\n  \u003cli\u003eScrew-in holding method for repeatable, rigid seating in toolholder\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement insert for SEAN-series compatible milling toolholders that accept a size 43 square insert with a 0.5000-inch inscribed circle and a 3\/16-inch nominal thickness.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist or CNC operator. Before changing inserts, ensure the spindle is fully stopped and the machine is locked out per applicable shop safety procedures. Use the correct torque driver for the clamping screw to avoid over-torquing the carbide insert. Inspect the toolholder pocket for debris or damage before seating the new insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: SEAN1204AFENLN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC725M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: SEAN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\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\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inches (1\/2 inch nominal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1874 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\u003eCorner Radius\u003c\/strong\u003e: 0.0449 inches (1.14 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 20 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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: 43\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0163 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: 1157895\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51749511397682,"sku":"1157895","price":246.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f92addd586138f8d62a2ded97f5eb104.jpg?v=1788907024","url":"https:\/\/voomisupply.com\/products\/kennametal-1157895-sean1204afenln-kc725m-milling-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
