The 0.024-inch cutting diameter and 0.072-inch length of cut make this tool well-suited for fine-detail work where dimensional accuracy is critical. Micrograin carbide construction provides the hardness and edge retention required for tight-tolerance applications. The bright, uncoated finish is standard for this class of miniature tooling. Four flutes and a 30-degree right-hand helix promote chip evacuation and surface finish quality in shallow-depth passes.\u003c\/p\u003e\u003cp\u003eThis end mill fits into high-speed CNC machining centers and manual mills used in tool-and-die, mold-making, medical device machining, and precision parts production. The 1\/8-inch shank diameter is compatible with standard collet systems commonly found in vertical machining centers. The single-end configuration and 1.5-inch overall length allow use in close-clearance setups typical in miniature mold cavity work and micro-feature engraving.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.024-inch ball nose cutting diameter for fine-detail and micro-feature milling\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for hardness and edge retention\u003c\/li\u003e\n\u003cli\u003e4-flute, right-hand spiral design promotes chip flow and surface finish\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle balances cutting force and chip evacuation\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for non-ferrous and general-purpose applications\u003c\/li\u003e\n\u003cli\u003eMiniature series with 1\/8-inch shank for standard collet compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard miniature ball end mill for CNC vertical machining centers and manual mills equipped with 1\/8-inch collet systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the 1\/8-inch shank fully into the collet and torque the collet nut according to the collet manufacturer specifications. At this diameter, tool runout is critical — verify runout with a dial indicator before beginning a cut to avoid premature tool breakage.\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: 0.072 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 (1\/8 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\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\u003eSingle or Double End\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\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: 12276917\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738604863794,"sku":"12276917","price":40.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d07f23312b14c92618053adab3a77a5e.jpg?v=1788801646","url":"https:\/\/voomisupply.com\/products\/accupro-12276917-ball-end-mill-0-024-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
