The cutting diameter measures 0.0550 inches with a length of cut of 0.1650 inches, making it suited for small-radius contour milling, slotting, and 3D profiling passes. The 2-flute geometry and 30-degree right-hand spiral helix promote efficient chip evacuation at elevated spindle speeds. Micrograin carbide construction provides rigidity and edge retention in hardened and abrasive workpiece materials. This end mill ships in a bright, uncoated finish and is configured as a single-end tool.\u003c\/p\u003e\u003cp\u003eThis miniature ball end mill is used in CNC machining centers and manual mills where small-diameter, high-precision cutting is required. Typical applications include die and mold work, medical component machining, aerospace detail parts, and intricate fixturing. The 1\/8-inch shank diameter fits standard collets and tool holders common to benchtop and full-size vertical machining centers. The 1.5-inch overall length keeps overhang minimal, supporting rigidity during fine finishing passes in shallow-to-moderate cavity depths.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0550-inch ball nose cutting diameter for fine-detail and contour work\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for edge retention in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003e2-flute, 30-degree right-hand helix for efficient chip flow at high RPM\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suitable for a wide range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with 1\/8-inch shank for compatibility with standard collets\u003c\/li\u003e\n\u003cli\u003eTight diameter tolerance of +0.0000 \/ -0.0010 inches for repeatable fitment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style miniature ball end mill for use in standard 1\/8-inch collet or tool holder systems on CNC and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and de-energized before changing tooling. Seat the shank fully into the collet to the recommended engagement depth and torque the collet nut per the tool holder manufacturer specification. At 0.0550-inch diameter, this tool is susceptible to breakage from excessive feed rate, runout, or improper clamping — verify TIR before production runs.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.0550 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 0.1650 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\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\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: 0.1 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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12463685\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732699775282,"sku":"12463685","price":29.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1091a534ee4224e82a82ef1baa4d1885.jpg?v=1788745841","url":"https:\/\/voomisupply.com\/products\/accupro-12463685-ball-end-mill-0-0550-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
