With a 0.438-inch (7\/16-inch) mill diameter, a 1-inch length of cut, and four medium-helix flutes, it delivers clean profiles in contouring, slotting, and profiling applications. The AlTiN+ coating provides elevated heat resistance and extended tool life when cutting at high speeds or in dry-machining environments. Overall length is 2.75 inches, and the cylindrical shank diameter matches the cutter at 0.438 inches for direct chuck or collet mounting. Machinists and CNC operators in job shops, aerospace, and moldmaking environments are the primary users of this tooling.\u003c\/p\u003e\u003cp\u003eThis end mill suits light-to-moderate milling passes on ferrous alloys, stainless steels, hardened tool steels, and high-temperature alloys where the AlTiN+ coating excels over standard TiN or TiAlN finishes. The ball nose geometry makes it the correct choice for 3D contouring, radius profiling, and finish passes on curved surfaces. It is a single-piece solid carbide tool with no chipbreaker and no extended reach, appropriate for standard-depth applications in vertical machining centers and CNC mills.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.438-inch (7\/16-inch) ball nose diameter for precise radius profiling and 3D contouring\u003c\/li\u003e\n\u003cli\u003eAlTiN+ coating for superior heat resistance and tool life in high-speed dry cutting\u003c\/li\u003e\n\u003cli\u003e4-flute medium configuration balances chip evacuation and surface finish\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and dimensional stability\u003c\/li\u003e\n\u003cli\u003eCylindrical shank at 0.438 inches for standard ER collet or end mill holder mounting\u003c\/li\u003e\n\u003cli\u003eNo chipbreaker and no extended reach — optimized for standard-depth finish passes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide ball end mill for use in standard CNC vertical machining centers and manual mills accepting a 7\/16-inch cylindrical shank toolholder or ER collet chuck.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down or in a safe tool-change state before inserting or removing the tool. Seat the shank fully into the collet or end mill holder to the recommended gauge-line depth and torque the retention hardware per the toolholder manufacturer specifications. Inspect the cutting edges and coating for chips or wear before each use; a damaged ball nose profile will transfer directly to the workpiece surface.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.438 inches (7\/16 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.438 inches (7\/16 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Medium\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\u003eShank Type\u003c\/strong\u003e: Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.8 inches L x 0.44 inches W x 0.44 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.18 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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 14788686\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51729202970930,"sku":"14788686","price":107.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7e4f775cfebbdabc026dd2ec9222f71f.jpg?v=1788701902","url":"https:\/\/voomisupply.com\/products\/accupro-14788686-ball-end-mill-0-438-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
