The cutter measures 0.034 inches in diameter with a 0.051-inch length of cut and a 1.5-inch overall length. The 1\/8-inch shank diameter fits standard collets used on CNC machining centers and manual mills. Four flutes in a right-hand spiral configuration with a 30-degree helix angle provide efficient chip evacuation and stable cutting action at high RPM. The micrograin carbide substrate offers the hardness and wear resistance needed for accurate, repeatable cuts in ferrous and non-ferrous materials.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for finishing and semi-finishing operations in die and mold work, micro-component machining, and detail profiling where small-radius contours are required. The bright uncoated finish makes it a straightforward choice for non-ferrous metals, plastics, and graphite, where coating adhesion or reactivity is a concern. Machinists working with miniature parts, intricate cavity work, or fine-detail engraving will find this tool sized appropriately for those applications. It is a single-end tool, meaning the cutting geometry is on one end only.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.034-inch ball nose diameter for small-radius and detail profiling cuts\u003c\/li\u003e\n\u003cli\u003eFour-flute right-hand spiral with 30-degree helix for smooth chip flow at high spindle speeds\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for hardness, rigidity, and dimensional stability\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for non-ferrous metals, plastics, and graphite\u003c\/li\u003e\n\u003cli\u003e1\/8-inch shank fits standard ER and precision collet systems\u003c\/li\u003e\n\u003cli\u003eNo chipbreaker geometry for consistent finish on fine detail passes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style miniature ball end mill compatible with CNC machining centers, manual mills, and high-speed spindles accepting a 1\/8-inch collet or tool holder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed with the machine powered down and the spindle fully stopped. Secure the 1\/8-inch shank in a clean, properly sized collet or tool holder to the torque specification recommended by the collet manufacturer; do not use worn or oversized collets with miniature-diameter tooling. Verify runout with a dial indicator before cutting, as excessive runout at this diameter will accelerate tool wear and degrade surface finish. Follow your facility's safe tool-handling procedures when measuring or storing carbide end mills.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.034 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\u003eLength of Cut (LOC)\u003c\/strong\u003e: 0.051 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\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\u003eOverall Length (OAL)\u003c\/strong\u003e: 1.5 inches\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\u003eSingle or Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: 12277159\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51731883327794,"sku":"12277159","price":31.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b1bfe42677585647f0bcd80488654ae9.jpg?v=1788736041","url":"https:\/\/voomisupply.com\/products\/accupro-12277159-ball-end-mill-0-034-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
