It features a parallelogram shape with a 70-degree included angle, a positive 15-degree rake angle, and a 5\/16-inch corner radius. The insert carries the KC522M manufacturer grade and is finished with an AlTiN coating applied via PVD process, providing thermal resistance and edge hardness for demanding milling applications. At 0.177 inches thick and 0.328 inches wide, this screw-held insert is designed for right-hand cutting and is installed by machinists and CNC tooling technicians working with indexable milling toolholders.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for face milling and shoulder milling operations across a range of workpiece materials, including steel, stainless steel, cast iron, superalloys and titanium, and hard materials. The HD2 chip breaker geometry is intended for heavier depth-of-cut applications where controlled chip formation is critical. It fits standard EDPT-series toolholders and is appropriate for both production and job-shop environments running ferrous and difficult-to-machine alloys. The insert size code is 1408, and the screw-clamping method ensures positive insert seating under high cutting forces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with AlTiN PVD coating for heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003eKC522M grade optimized for steel, stainless steel, cast iron, superalloys and titanium, and hard materials\u003c\/li\u003e\n  \u003cli\u003eHD2 chip breaker geometry for controlled chip evacuation in heavy-cut conditions\u003c\/li\u003e\n  \u003cli\u003ePositive 15-degree rake angle reduces cutting forces and heat generation\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch corner radius (0.3125 inches decimal) for strength at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eScrew-held mounting method ensures rigid, repeatable insert positioning\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting orientation; parallelogram insert shape with 70-degree included angle\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for EDPT-series indexable milling toolholders accepting size 1408 inserts with screw-clamp retention.

Use the correct torx or hex key specified by the toolholder manufacturer when tightening the clamping screw — do not overtighten. Inspect the insert pocket and seating surface for chips or debris before seating the insert. Replace the insert at first signs of edge wear to avoid workpiece damage or toolholder damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Designation\u003c\/strong\u003e: EDPT140408PDERHD2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC522M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: EDPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Parallelogram\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: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: HD2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\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: 15 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 70 degrees\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: 1408\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.6875 inches (0.6500 to 0.7000 inches range)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.328 inches (21\/64 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.177 inches (4.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.3125 inches (5\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1339 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01072 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys and Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Material Codes\u003c\/strong\u003e: P, M, K, S, H\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: 5477299\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51748738695474,"sku":"5477299","price":45.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a14dc518d65543b7abc4048c47804d41_fe78e9ab-71e4-42f2-af96-6c7253f95c85.jpg?v=1788897568","url":"https:\/\/voomisupply.com\/products\/kennametal-5477299-milling-insert-kc522m-solid-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
