With a 0.031-inch cutting diameter and a 3-flute helical geometry at a 30-degree helix angle, this tool delivers smooth chip evacuation and consistent surface finish across a wide range of materials. The long-reach, stub-flute configuration extends usable reach to 0.25 inches while keeping the flute length short at 0.046 inches, improving rigidity and reducing deflection during fine-detail cutting passes. It is single-end, right-hand cut, and ships uncoated. Machinists and tool-and-die professionals install this tool in CNC machining centers handling small-component and finish work.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling steel, stainless steel, cast iron, and non-ferrous metals in both roughing and finishing applications. The stub flute length supports stability when milling at depth with minimal sidewall clearance. The 1\/8-inch straight-cylindrical shank fits standard collet chucks found on most CNC mills and high-speed spindles. Typical use cases include die cavities, medical components, aerospace features, and any small-part application requiring a sub-1mm ball profile with extended reach access.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.031-inch (0.80 mm) ball nose diameter with a nose radius of 0.0155 inches for precise small-radius contouring\u003c\/li\u003e\n  \u003cli\u003e3-flute helical geometry at 30-degree helix angle for balanced chip evacuation and surface finish\u003c\/li\u003e\n  \u003cli\u003eLong-reach design with 0.25-inch reach length and 0.046-inch length of cut for access in deep or narrow features\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and wear resistance at miniature diameters\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suitable for use with or without coolant on a broad material range\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute, single-end configuration for standard CNC spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement and standard miniature ball end mill for CNC machining applications requiring a 1\/8-inch shank and sub-millimeter cutting diameter.

Power down the spindle and confirm the tool changer or spindle is fully stopped before installing or removing the tool. Seat the shank fully in a clean, dry collet or tool holder and torque the collet nut to the holder manufacturer specification. Verify runout with a dial indicator before starting a cut, as runout has a significant effect on tool life and surface quality at miniature diameters.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.031 inches (0.80 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 0.046 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2.5 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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.204 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.0155 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: 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\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\u003eFlute Type\u003c\/strong\u003e: Helical\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\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0005 \/ -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HARVEY TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 34231\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51747965632818,"sku":"34231","price":82.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e3b0e8adba3163498b914aea1ea43c51_3e1d83e4-801b-469b-806a-73bfdf301997.jpg?v=1788887510","url":"https:\/\/voomisupply.com\/products\/harvey-tool-34231-ball-end-mill-0-031-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
