With a 0.0156 inch (1\/64 inch) mill diameter and a 0.022 inch length of cut, this tool is engineered for micro-scale profiling, contouring, and slot milling where dimensional accuracy is critical. The AlTiN coating provides thermal resistance and extended tool life in dry or minimal-lubrication cutting environments. Three flutes in a right-hand spiral configuration improve chip evacuation and surface finish at elevated feed rates. Micrograin carbide substrate adds edge rigidity at this fine diameter.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for CNC machining centers and high-speed spindle applications where small-radius ball-nose geometry is required. The extended-reach neck design and 1\/8 inch shank diameter make it compatible with standard collet chucks used in die and mold work, medical component machining, and precision part production. The miniature series designation indicates this tool is intended for fine-detail cuts rather than bulk material removal. It is a single-end tool, used once the cutting end is worn.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0156 inch (1\/64 inch) ball nose diameter for micro-scale milling\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for thermal resistance and extended tool life in hard materials\u003c\/li\u003e\n\u003cli\u003e3-flute right-hand spiral geometry for improved chip flow and finish quality\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for edge stability at small diameters\u003c\/li\u003e\n\u003cli\u003eExtended reach neck with 0.078 inch neck length for deep-cavity access\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle balances cutting force and chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and high-speed spindles accepting a 1\/8 inch shank via ER or precision collet chuck.

Ensure the spindle is fully stopped and de-energized before inserting or removing the tool from the collet. Use a precision torque wrench and the appropriate collet nut wrench when seating the 1\/8 inch shank to avoid micro-fractures at this diameter. At 0.0156 inch diameter, runout must be minimized — verify collet condition and cleanliness before clamping.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.0156 inches (1\/64 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 0.022 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\u003c\/strong\u003e: AlTiN\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\u003eOverall Length (OAL)\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.078 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\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\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: 14881909\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728225960242,"sku":"14881909","price":66.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/69107d4b5cae4423b5da017e1445643c.jpg?v=1788689888","url":"https:\/\/voomisupply.com\/products\/accupro-14881909-ball-end-mill-0-0156-in-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
