Built from micrograin solid carbide, it carries a 0.025-inch cutting diameter with a 0.075-inch length of cut and a 4-flute spiral configuration at a 30-degree helix angle. The bright, uncoated finish makes it well-suited for non-ferrous metals, plastics, and other materials where coating adhesion is a concern. This is a single-end tool with right-hand cutting and right-hand flute direction, intended for use in CNC machining centers and precision manual mills by machinists and toolroom professionals.\u003c\/p\u003e\u003cp\u003eThis miniature end mill is used in applications requiring fine detail work, such as mold and die finishing, engraving, micro-slot milling, and contour work on small workpieces. The 0.025-inch diameter makes it appropriate for intricate cuts where larger tooling cannot reach. Its 1\/8-inch shank diameter accommodates standard collet systems commonly found in both vertical machining centers and high-speed spindles. The Miniature series designation indicates this tool is built for small-scale, high-precision work in both production and prototype environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.025-inch ball nose cutting diameter for fine detail and contour milling\u003c\/li\u003e\n\u003cli\u003e4-flute spiral design at 30-degree helix for smooth chip evacuation and surface finish\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance in precision applications\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for non-ferrous metals and plastics\u003c\/li\u003e\n\u003cli\u003eSingle-end, right-hand cut with 1\/8-inch shank for standard collet compatibility\u003c\/li\u003e\n\u003cli\u003e1.5-inch overall length with 0.075-inch length of cut for reach in confined areas\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style miniature ball end mill compatible with standard 1\/8-inch collet systems used in CNC machining centers, high-speed spindles, and precision toolroom mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed by qualified machinists with the spindle fully de-energized and locked out per facility lockout\/tagout procedures. Ensure the collet and collet nut are clean and free of debris before seating the 1\/8-inch shank. At this diameter, tool runout must be minimized; verify runout with a dial indicator before cutting. Follow appropriate feeds and speeds for the workpiece material to avoid tool breakage on this miniature tool.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.025 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.075 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\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003c\/strong\u003e: 1.5 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\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\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\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: 12276918\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732531675442,"sku":"12276918","price":33.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3fbe7728ec11277d77c5f8e11b38dcf8.jpg?v=1788744114","url":"https:\/\/voomisupply.com\/products\/accupro-12276918-ball-end-mill-0-025-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
