Built to the F4AS series specification, it features a 16 mm cutting diameter, a 32 mm length of cut, and a 38-degree helix angle that promotes efficient chip evacuation. The corner chamfer end geometry reduces edge chipping at the entry point and extends tool life in demanding applications. An AlTiN coating provides thermal resistance and hardness at elevated cutting temperatures, making this end mill well-suited for high-speed machining of ferrous alloys and hardened steels. Installed by machinists and CNC operators, this tool fits standard milling setups requiring a 16 mm Weldon flat shank.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in precision machining environments where a single tool must handle both roughing passes and finishing passes. The right-hand flute direction and right-hand cutting orientation are standard for conventional vertical and horizontal milling centers. The center-cutting capability allows plunge entry, adding flexibility for pocketing and slotting operations. With an overall length of 92 mm and no extended reach configuration, it is suited for shallow to mid-depth features in ferrous and non-ferrous workpieces across job shop and production settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in high-speed cuts\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating delivers thermal and oxidation resistance at elevated cutting temperatures\u003c\/li\u003e\n  \u003cli\u003e38-degree helix angle promotes aggressive chip evacuation and reduces heat buildup\u003c\/li\u003e\n  \u003cli\u003eCorner chamfer end geometry reduces edge chipping and extends tool life\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows direct plunge entry for pocketing and slotting\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank provides positive drive and reduces slippage under heavy loads\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide end mill in the KENNAMETAL F4AS series, compatible with standard milling machine spindles and toolholders accepting a 16 mm Weldon flat shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool changer is disabled before handling or changing end mills. Secure the Weldon flat against the setscrew in the toolholder to the toolholder manufacturer specification before engaging the spindle. Verify runout with a dial indicator after installation to confirm concentricity before beginning a cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 16 mm (0.6299 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 32 mm (1.2598 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 92 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 16 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Chamfer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Length\u003c\/strong\u003e: 0.0500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: F4AS\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\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: 4046277\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51739272053042,"sku":"4046277","price":638.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0fd53c86212dae43a5dd8ce85fca1868.jpg?v=1788812496","url":"https:\/\/voomisupply.com\/products\/kennametal-4046277-end-mill-16mm-4-flute-altin-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
