With a 0.0650-inch cutting diameter and a 0.0970-inch length of cut (LOC), this tool is built for miniature-series work where accuracy and rigidity are critical. The 4-flute geometry and 30-degree helix angle promote smooth chip evacuation and stable cutting action in both ferrous and non-ferrous materials. Micrograin carbide construction provides the hardness and edge retention needed for fine-detail work. The bright\/uncoated finish makes this tool suitable for a wide range of workpiece materials without coating interference.\u003c\/p\u003e\u003cp\u003eThis end mill is used in CNC machining centers and manual mills for contouring, slotting, and 3D profiling of small features. It is particularly well-suited for mold and die work, medical component machining, and precision aerospace part production where small-diameter tooling is required. The single-end configuration and 1\/8-inch shank diameter make it compatible with standard ER collet systems and miniature toolholders commonly found in production and job-shop environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0650-inch ball nose diameter for fine-detail and small-feature milling\u003c\/li\u003e\n\u003cli\u003e4-flute design with 30-degree right-hand helix for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for superior hardness and edge retention\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suitable for a broad range of workpiece materials\u003c\/li\u003e\n\u003cli\u003e1\/8-inch shank diameter compatible with standard miniature collet systems\u003c\/li\u003e\n\u003cli\u003eSingle-end, right-hand cutting direction for standard CNC and manual mill use\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 ER collet toolholders and miniature milling chucks accepting a 1\/8-inch shank diameter.\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 an e-stop or powered-down state before changing tooling. Seat the shank fully into the collet to the recommended engagement depth and torque the collet nut per the toolholder manufacturer specifications. Inspect the cutting edges for chips or damage before each use, as small-diameter carbide tooling is brittle and sensitive to runout.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.0650 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 0.0970 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\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\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\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\u003ePackage Weight\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: 12277190\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51750752485682,"sku":"12277190","price":30.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/16afe7976f358ad4a2854711ce6a8dd1.jpg?v=1788919356","url":"https:\/\/voomisupply.com\/products\/accupro-12277190-ball-end-mill-0-065-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
