Built on the F4AS series platform, it features a 4 mm cutting diameter, 4 flutes, and a corner chamfer end geometry that reduces edge chipping at the entry point of each pass. The AlTiN coating improves heat resistance and tool life in ferrous and hard materials. With a 38-degree helix angle, the tool promotes efficient chip evacuation and reduces cutting forces during full-depth slotting or side milling operations. Licensed machinists and CNC tool-path programmers install this end mill in machining centers and vertical mills.\u003c\/p\u003e\u003cp\u003eThe 4046263 is suited for ferrous metals, hardened steels, stainless, and cast materials where a single tool must handle both roughing and semi-finish operations without a tool change. The 12 mm length of cut accommodates moderate axial depth passes, while the 55 mm overall length keeps the tool stiff enough to resist deflection in tight setups. The 4 mm straight cylindrical shank seats directly in collet chucks, shrink-fit holders, or milling chucks with a matching 4 mm bore. It is a single-end, right-hand cut, right-hand flute tool appropriate for standard CNC milling programs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4 mm cutting diameter with matching 4 mm straight cylindrical shank for direct collet seating\u003c\/li\u003e\n\u003cli\u003eCorner chamfer end geometry reduces edge chipping and extends tool life at cut entry\u003c\/li\u003e\n\u003cli\u003eAlTiN coating provides elevated heat resistance for dry or minimal-lubrication machining in ferrous materials\u003c\/li\u003e\n\u003cli\u003e38-degree helix angle promotes chip evacuation and lowers radial cutting forces\u003c\/li\u003e\n\u003cli\u003e12 mm length of cut allows moderate axial depth in roughing and semi-finish passes\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable, supporting plunge entry into the workpiece\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard CNC machining centers and vertical mills accepting 4 mm straight cylindrical shank tooling; part of the KENNAMETAL F4AS series of roughing finishing end mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. Power down and lock out the spindle before loading or removing any end mill. Seat the shank fully in the holder to the recommended gauge line and torque the collet nut or set screw to the holder manufacturer specification before running. Inspect the cutting edges and coating condition before each use; do not run a chipped or worn tool, as corner chamfer geometry is especially sensitive to re-entry damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 4 mm (0.2362 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: 12 mm (0.4724 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 55 mm (2.17 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\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\u003eCenter Cutting\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\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: 4046263\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51738428277042,"sku":"4046263","price":85.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/39e3f7e8d6691a69728554fff542a33d.jpg?v=1788799422","url":"https:\/\/voomisupply.com\/products\/kennametal-4046263-roughing-finishing-end-mill-4mm-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
