It features a 1\/8 inch diameter, a 3-flute right-hand spiral configuration, and a 30-degree helix angle that balances cutting efficiency with surface finish quality. The stub flute geometry paired with a long-reach design — 1.25 inches of reach length — allows access to deep features without sacrificing rigidity. At 2.5 inches overall length with a 3\/16 inch length of cut, this tool is built for tight-tolerance work in steel, stainless steel, cast iron, and non-ferrous metals. Machinists and toolroom technicians use it for both roughing and finishing passes in a single setup.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for CNC machining centers and manual mills where small-diameter tooling is required. The long-reach, stub-flute configuration is commonly applied in mold and die work, medical component machining, and aerospace part production where deep cavities or restricted clearance require extended reach without sacrificing cutting control. The bright, uncoated finish makes it appropriate for applications where coating interaction with the workpiece or cutting fluid is a concern. It is a single-end tool with a straight cylindrical 1\/8 inch shank compatible with standard collet chucks and end mill holders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in steel, stainless steel, cast iron, and non-ferrous metals\u003c\/li\u003e\n  \u003cli\u003e3-flute, right-hand spiral design with 30-degree helix angle for balanced cutting and chip evacuation\u003c\/li\u003e\n  \u003cli\u003eLong-reach geometry with 1.25 inches of reach length and stub flute for deep-feature access\u003c\/li\u003e\n  \u003cli\u003eBall nose profile supports 3D contouring, profiling, and blending operations\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish compatible with a wide range of cutting fluids and workpiece materials\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration with a straight cylindrical shank for standard collet and end mill holder mounting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-series miniature ball end mill in the HARVEY TOOL Miniature End Mills - Ball - Long Reach, Stub Flute series.

Ensure the machine spindle is fully stopped and the tool changer or spindle is locked before inserting or removing the tool. Seat the shank to the minimum recommended insertion depth in the collet or holder to maximize rigidity and minimize runout. Verify runout with a dial indicator before beginning a cut, especially given the small diameter, as excessive runout will accelerate tool wear and reduce dimensional accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.1250 inches (1\/8 inch)\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\/16 inch (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5000 inches (2-1\/2 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1250 inches (1\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 1.2500 inches (1-1\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 1.0630 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.0625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\u003eSingle or Double End\u003c\/strong\u003e: Single\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: +0.0000 \/ -0.0020 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\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: 966108\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51730059788594,"sku":"966108","price":85.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0156aeb88a8a39d5617e4b1ffbb56b06.jpg?v=1788711000","url":"https:\/\/voomisupply.com\/products\/harvey-tool-966108-ball-end-mill-1-8-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
