With a 1\/32 inch (0.031 inch) cutting diameter and a stub flute length of 3\/64 inch, this three-flute tool delivers accurate ball-nose profiling in steel, stainless steel, cast iron, and non-ferrous metals. The 30-degree helical flute geometry promotes efficient chip evacuation while maintaining rigidity at this small diameter. It is a single-end, right-hand cut, right-hand flute tool with an uncoated bright finish. Machinists and CNC programmers working on dies, molds, fine detail features, and medical or aerospace components will find this tool well suited to their requirements.\u003c\/p\u003e\n\u003cp\u003eThis end mill is built for miniature and micro-milling operations on CNC machining centers and high-speed spindles. The long-reach configuration, with a 7\/32 inch reach length and a 0.171 inch neck length, allows the tool to access recessed features and deep pockets without interference from the shank. The 1\/8 inch straight cylindrical shank fits standard ER collet systems commonly used in precision machining setups. It is appropriate for both roughing and finishing passes on workpieces in steel (P), stainless steel (M), cast iron (K), and non-ferrous metal (N) material classifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/32 inch ball nose diameter with tight tolerance of plus 0.0005 \/ minus 0.0005 inch for precise profiling\u003c\/li\u003e\n  \u003cli\u003eThree-flute helical design at 30 degrees supports both roughing and finishing in a single tool\u003c\/li\u003e\n  \u003cli\u003eLong-reach, stub-flute geometry with 7\/32 inch reach length for access to deep or recessed features\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance at miniature diameters\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for a broad range of workpiece materials including non-ferrous metals\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and flute direction; compatible with standard CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers equipped with high-speed spindles and ER collet toolholding systems accepting a 1\/8 inch straight cylindrical shank.

Ensure the spindle is fully stopped and the machine is in a safe state before loading or changing the tool. Seat the 1\/8 inch shank fully into the collet and torque the collet nut to the toolholder manufacturer specification. At miniature diameters, runout control is critical — verify tool runout with a dial indicator before commencing cuts to avoid premature tool breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/32 inch (0.031 inch \/ 0.80 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/64 inch (1.20 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches (2.5 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 7\/32 inch (0.218 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.171 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.0155 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: plus 0.0005 \/ minus 0.0005 inch\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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\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\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\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\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\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Miniature End Mills - Ball - Long Reach, Stub Flute\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: 868231\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51752496857394,"sku":"868231","price":81.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/25c80000fa7fda4f09397dd5f9ada5ce.jpg?v=1788928621","url":"https:\/\/voomisupply.com\/products\/harvey-tool-868231-ball-end-mill-1-32-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
