With a 0.0200-inch mill diameter and a 0.0300-inch length of cut, this tool is built for fine detail work in tight geometries. The 4-flute, right-hand spiral configuration with a 30-degree helix angle promotes efficient chip evacuation and smooth surface finish. Constructed from micrograin solid carbide, the tool delivers the rigidity and edge retention needed for demanding cuts at small scales. The bright, uncoated finish suits a wide range of workpiece materials. Licensed machinists and precision CNC operators are the primary installers of this tooling.\u003c\/p\u003e\u003cp\u003eThis ball end mill is suited for 3D contouring, slotting, and finishing passes in mold work, die making, medical device components, and other tight-tolerance applications where small feature detail is critical. The miniature series designation indicates it is purpose-built for micro-scale milling rather than general-purpose stock removal. The single-end design allows direct installation into standard collet systems accepting a 1\/8-inch shank. It is appropriate for use on CNC machining centers and high-speed spindles capable of running small-diameter tooling at elevated RPM.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0200-inch ball end mill diameter for micro-scale precision milling\u003c\/li\u003e\n\u003cli\u003e0.0300-inch length of cut suits shallow, fine-detail passes\u003c\/li\u003e\n\u003cli\u003e4-flute, right-hand spiral with 30-degree helix for smooth chip flow\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for edge retention and rigidity\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish for versatility across a range of materials\u003c\/li\u003e\n\u003cli\u003e1\/8-inch shank diameter fits standard collet systems\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 collet holders and tool chucks accepting a 1\/8-inch shank diameter, typical in CNC machining center applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes must be performed with the spindle fully stopped and the machine control in a safe, locked-out state per shop safety protocols. Use a properly sized, clean collet or tool holder to ensure accurate runout; contamination or a worn collet will magnify runout error significantly at this diameter. Verify spindle speed and feed rate settings before engaging the cut, as small-diameter carbide tooling is sensitive to deflection and breakage at incorrect parameters. Handle with care to avoid chipping the cutting edges.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.0200 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 0.0300 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\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\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\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 Configuration\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Miniature\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.75 x 0.75 x 0.75 inches\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: 12277145\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728520806706,"sku":"12277145","price":36.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/62c45cabff3b5dcadb6f25c91f268d54.jpg?v=1788692623","url":"https:\/\/voomisupply.com\/products\/accupro-12277145-ball-end-mill-0-02-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
