With a 0.0120-inch cutting diameter and a 0.0180-inch length of cut (LOC), this tool is built for fine detail work in hardened and difficult-to-machine materials. The micrograin carbide construction provides the rigidity and edge retention needed to hold dimensional accuracy at this scale. A 30-degree helix angle promotes efficient chip evacuation during high-speed passes. Machinists and tooling professionals working on small components, molds, or intricate features will find this single-end configuration well suited to their setups.\u003c\/p\u003e\u003cp\u003eThis ball end mill is intended for use in CNC machining centers and precision manual mills where sub-0.025-inch diameter tooling is required. Typical applications include micro-mold work, engraving, fine contouring, and detail finishing passes on aerospace, medical, and electronics components. The 1\/8-inch shank diameter allows it to seat in standard collet chucks commonly found in high-speed spindles. Its bright, uncoated finish makes it suitable for a range of base materials where coating interaction is a concern.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0120-inch ball nose diameter for micro-scale milling and fine detail work\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for edge retention and wear resistance\u003c\/li\u003e\n\u003cli\u003e4-flute spiral geometry with 30-degree right-hand helix for efficient chip flow\u003c\/li\u003e\n\u003cli\u003e0.0180-inch length of cut (LOC) keeps deflection minimal at this diameter\u003c\/li\u003e\n\u003cli\u003e1.5-inch overall length with 1\/8-inch shank for compatibility with standard collet systems\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable where coating is not required or desired\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 CNC machining centers and precision milling spindles accepting a 1\/8-inch shank collet.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Seat the 1\/8-inch shank fully into a clean, properly sized collet before torquing to the spindle manufacturer's specification. At this diameter, runout is critical — verify runout with a test indicator before cutting. Always confirm spindle speed and feed rate are appropriate for the workpiece material and tool diameter before engaging the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.0120 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 0.0180 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 Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Configuration\u003c\/strong\u003e: Single End\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\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: 12277137\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728451436850,"sku":"12277137","price":39.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cc77461f21deb87fff88e56ef87737b1.jpg?v=1788691392","url":"https:\/\/voomisupply.com\/products\/accupro-12277137-ball-end-mill-0-012-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
