It carries a 5\/64 inch (0.0781 inch) mill diameter and a 1\/8 inch shank diameter, making it well-suited for fine contouring, profiling, and slotting operations where standard-size tooling cannot reach. The three-flute, right-hand spiral geometry with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. Micrograin carbide construction delivers the rigidity and edge retention required for consistent performance in harder workpiece materials. The bright\/uncoated finish means the tool runs as-ground with no additional coating layer.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in CNC machining centers and manual mills for small-part production, mold and die work, medical components, aerospace detail parts, and electronics fixtures. With a 0.1170 inch length of cut, a 0.9400 inch neck length, and a 2-1\/2 inch overall length, it offers extended reach into recessed pockets and features while maintaining tool stiffness. It is a single-end tool intended for right-hand cutting. Machinists working with aluminum, brass, plastics, and light-to-medium steels will find this geometry effective for finishing passes and fine detail work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/64 inch (0.0781 inch) ball nose diameter for small-radius contouring and profiling\u003c\/li\u003e\n  \u003cli\u003eThree-flute right-hand spiral design with 30-degree helix for efficient chip flow\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide construction for superior edge retention and rigidity\u003c\/li\u003e\n  \u003cli\u003eExtended reach with 0.9400 inch neck length and 2-1\/2 inch overall length\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish — no coating buildup at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration with 1\/8 inch straight shank for standard collet holding\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use miniature end mill compatible with CNC machining centers, knee mills, and toolroom mills fitted with 1\/8 inch collet chucks or ER-style collet systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following standard toolholding procedures. Secure the 1\/8 inch shank fully into a collet or end mill holder to the recommended gauge-line depth before tightening. Verify runout at the tool tip prior to cutting, as miniature carbide tools are sensitive to clamping-induced deflection. Avoid side-loading the tool during entry; use ramping or helical interpolation entry moves to protect the fragile ball geometry.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/64 inch (0.0781 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 0.1170 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.9400 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 \/ -0.0010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0003 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Miniature\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 14881978\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732901200178,"sku":"14881978","price":53.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/06dd4ed837bce98f6bcc81f39f02cb62.jpg?v=1788748467","url":"https:\/\/voomisupply.com\/products\/accupro-14881978-ball-end-mill-5-64-in-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
