With a 0.024-inch cutting diameter and four flutes, it delivers fine surface finishes and controlled chip evacuation in demanding small-part applications. The micrograin carbide substrate provides the edge integrity required when working at reduced diameters where tool deflection and breakage are primary concerns. A 30-degree helix angle balances cutting forces and chip flow in both ferrous and non-ferrous materials. This tool is intended for use by machinists and tooling professionals operating CNC mills, machining centers, and precision manual mills.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for finishing and semi-finishing passes in mold and die work, medical component machining, aerospace detail parts, and other small-scale precision machining applications. The miniature series designation reflects its geometry and shank configuration, making it appropriate for high-RPM spindles and micro-machining setups. The 1\/8-inch shank diameter is compatible with standard collet systems used in precision machining centers. The single-end design means it is replaced rather than reindexed at end of life.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.024-inch ball nose cutting diameter for fine-detail and small-radius milling\u003c\/li\u003e\n\u003cli\u003eFour-flute spiral geometry for improved finish and chip removal at reduced diameters\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003e30-degree right-hand helix with right-hand cutting direction\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for non-ferrous, ferrous, and general-purpose materials\u003c\/li\u003e\n\u003cli\u003eMiniature series, single-end design with 0.036-inch length of cut\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 chucks and compatible toolholders on CNC machining centers and precision mills requiring reduced-diameter tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist familiar with tool runout tolerances and collet torque procedures for small-diameter carbide tooling. Ensure the spindle and toolholder are clean and free of debris before seating the 1\/8-inch shank to avoid tool deflection or premature breakage. Carbide end mills at this diameter are brittle and should not be used for interrupted cuts or plunge milling without appropriate programming feeds and speeds. Follow machine tool manufacturer guidelines and applicable shop safety procedures when handling and setting micro-diameter tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.024 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 0.036 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\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\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\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\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: 12277149\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51729271095602,"sku":"12277149","price":39.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1cf8de7b7f8f9b54cb65c06d4e26079d.jpg?v=1788702351","url":"https:\/\/voomisupply.com\/products\/accupro-12277149-ball-end-mill-0-024-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
