The cutting diameter is 0.0160 inches with a 0.0240-inch length of cut, making it suited for fine detail work in hardened and difficult-to-machine materials. Built from micrograin solid carbide, this tool delivers the rigidity and edge retention required in CNC milling environments. The 30-degree helix angle promotes efficient chip evacuation, and the bright uncoated finish keeps the tool geometry sharp from the start. Licensed machinists and CNC programmers working in tool and die, medical device, mold, and aerospace applications are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThis miniature ball end mill is used in vertical and horizontal CNC machining centers where small-radius contours, 3D surface profiling, and slot milling in confined areas are required. The 1\/8-inch shank diameter fits standard collet systems commonly used in high-speed spindle setups. Typical applications include finishing passes on complex contour surfaces, engraving, and micro-feature milling in ferrous and non-ferrous materials. The single-end configuration provides a straightforward setup with no need to flip or reindex the tool.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for edge retention in demanding materials\u003c\/li\u003e\n\u003cli\u003e0.0160-inch ball nose diameter with 0.0240-inch length of cut for fine-feature work\u003c\/li\u003e\n\u003cli\u003e4-flute design provides a good balance of chip clearance and surface finish\u003c\/li\u003e\n\u003cli\u003e30-degree right-hand helix promotes effective chip evacuation\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish maintains precise edge geometry out of the package\u003c\/li\u003e\n\u003cli\u003e1\/8-inch shank diameter fits standard high-speed spindle collet systems\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 high-speed spindle systems accepting a 1\/8-inch shank diameter collet.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully into the collet and torque the collet nut to the spindle manufacturer's specification. Verify runout with a dial indicator before beginning the first cut, as tool deflection at this diameter is critical to both tool life and part accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.0160 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.0240 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\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 Configuration\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Micrograin Solid Carbide\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\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\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: 12277141\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732662780210,"sku":"12277141","price":47.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b0619c126ec6a29400a2e2ad27c83f5c.jpg?v=1788745474","url":"https:\/\/voomisupply.com\/products\/accupro-12277141-ball-end-mill-0-0160-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
