The insert carries a TiAlN coating applied via PVD process, which provides thermal resistance and wear life suited to interrupted cuts and high-speed milling passes. It measures 0.4331 inches wide, 0.6299 inches long, and 0.25 inches thick, with a corner radius of 0.0315 inches (approximately 1\/32 inch). The parallelogram insert shape and 85-degree included angle suit shoulder milling and face milling toolholders designed for the ANGT insert family. Installation is performed by licensed machinists and tooling setup technicians working with compatible milling cutters.\u003c\/p\u003e\u003cp\u003eThis insert is engineered primarily for milling cast iron workpieces, consistent with its K-grade material classification and the LG chip breaker geometry. The LG chip breaker is optimized to manage the short, brittle chips produced when cutting gray cast iron, ductile iron, and similar ferrous materials. The right-hand orientation and screw-in holding method make it compatible with standard ANGT-style milling cutter bodies. Typical applications include face milling, shoulder milling, and high-feed milling operations on cast iron components in production machining environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eISO designation ANGT160608PPERLG with KC520M grade for cast iron milling\u003c\/li\u003e\n\u003cli\u003eTiAlN coating via PVD process for thermal wear resistance in dry or semi-dry cutting\u003c\/li\u003e\n\u003cli\u003eLG chip breaker geometry designed for controlled chip formation in cast iron\u003c\/li\u003e\n\u003cli\u003eParallelogram insert shape with 85-degree included angle for shoulder and face milling\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting orientation with screw-in insert holding method\u003c\/li\u003e\n\u003cli\u003eSolid carbide substrate in material grades C1 and C2\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a screw-in replacement insert for ANGT-series milling cutter bodies accepting the ANGT160608 insert size with a 0.1732-inch hole diameter.

Use the appropriate Torx or hex key specified by the cutter body manufacturer to secure the clamping screw — do not overtighten, as carbide inserts are brittle and will crack under excessive clamp load. Inspect the insert pocket and clamping screw for wear or debris before seating the new insert. Confirm insert orientation matches the right-hand designation before resuming cutting operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: ANGT160608PPERLG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: ANGT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Parallelogram\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC520M\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: LG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 85 degrees\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\u003eWidth\u003c\/strong\u003e: 0.4331 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.6299 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.25 inches\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: 1.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1323 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: 1586646\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51727452438834,"sku":"1586646","price":361.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4cf62c905cbf4f171a61ee678d1540c0.jpg?v=1788678077","url":"https:\/\/voomisupply.com\/products\/kennametal-1586646-milling-insert-kc520m-tialn-cast-iron","provider":"Voomi Supply","version":"1.0","type":"link"}
