Built from solid carbide with an AlTiN coating, this tool delivers hardness and heat resistance suited for cutting ferrous metals, stainless steels, and high-temperature alloys. It features a 0.315-inch mill diameter, a 0.6299-inch length of cut, and a 3-flute fine-pitch geometry. The 20-degree maximum helix angle promotes smooth chip evacuation and stable cutting action. This end mill is installed and operated by machinists and CNC tooling technicians in job shop and production environments.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in vertical machining centers, CNC milling machines, and manual knee mills where a corner chamfer profile is required. The centercutting design allows plunge entry, expanding its usefulness across a range of milling strategies including slotting, profiling, and chamfer blending. The fine pitch and 3-flute configuration suit applications in medium to hard workpiece materials. The 8 mm shank diameter fits standard collet systems and tool holders designed for that shank size. Typical applications include chamfering part edges, blending radii, and finishing operations in aerospace, die-mold, and general precision machining.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eAlTiN coating provides elevated heat resistance and extended tool life in dry or semi-dry cutting\u003c\/li\u003e\n\u003cli\u003eCorner chamfer end type for chamfered-edge profile milling\u003c\/li\u003e\n\u003cli\u003eCentercutting capable, allowing plunge and ramp entry\u003c\/li\u003e\n\u003cli\u003e3-flute fine-pitch geometry balances chip clearance and surface finish\u003c\/li\u003e\n\u003cli\u003e0.30 mm chamfer width for controlled, repeatable edge geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard tool holders and collet systems accepting an 8 mm shank diameter.

Always ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Secure the shank fully in the collet or tool holder to the manufacturer-specified engagement depth before tightening. Verify runout with an indicator after installation, as excessive runout accelerates wear and degrades chamfer accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.315 inches (8.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.6299 inches (16.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 63 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill 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\u003eEnd Type\u003c\/strong\u003e: Corner Chamfer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Width\u003c\/strong\u003e: 0.30 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Helix Angle\u003c\/strong\u003e: 20 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Fine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: F3BH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.48 inches length x 0.31 inches width x 0.31 inches height\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 4047069\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51730145214770,"sku":"4047069","price":235.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ae284f86742cb3dc6995312c65a881b5.jpg?v=1788712520","url":"https:\/\/voomisupply.com\/products\/kennametal-4047069-corner-chamfer-end-mill-0-315in-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
