It features a 0.04 inch mill diameter, a 0.06 inch length of cut (stub flute), and a 2.5 inch overall length with extended reach capability. The 3-flute, right-hand helical design with a 30-degree helix angle balances chip evacuation and surface finish across a range of materials. Solid carbide construction delivers the rigidity and edge retention needed for consistent results at this scale. The bright uncoated finish suits applications where coating buildup or heat sensitivity is a concern.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling steel, stainless steel, cast iron, and non-ferrous metals in both roughing and finishing passes. The long-reach, stub-flute geometry makes it well matched for contouring, profiling, and accessing recessed features where a standard-length flute would deflect or chatter. Typical applications include mold and die work, precision machining of medical or aerospace components, and small-part fabrication requiring tight dimensional tolerances. The 0.125 inch straight-cylindrical shank fits standard collet chucks and toolholders designed for 1\/8 inch shanks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.04 inch ball nose diameter with a 0.02 inch nose radius for fine contour work\u003c\/li\u003e\n\u003cli\u003e3-flute right-hand helical design at 30-degree helix for balanced cutting and chip flow\u003c\/li\u003e\n\u003cli\u003eExtended reach with 0.48 inch reach length and 0.42 inch neck length for deep-feature access\u003c\/li\u003e\n\u003cli\u003eStub flute (0.06 inch LOC) reduces deflection at miniature diameters\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and edge life in ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish compatible with a wide range of workpiece materials and cutting fluids\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on CNC machining centers and high-speed spindles capable of the RPM ranges required for miniature-diameter carbide tooling.

Ensure the spindle and toolholder are clean and free of runout before seating the shank; excess runout at miniature diameters accelerates tool wear and can cause breakage. Verify collet clamping torque per the toolholder manufacturer specification before starting a cut. Coolant-through is not supported on this tool; apply external flood or mist coolant as appropriate for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.04 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.02 inches\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 (LOC)\u003c\/strong\u003e: 0.06 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.48 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.42 inches\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\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: Helical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting 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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0005 \/ -0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Bright \/ Uncoated\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 35640\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51729301471538,"sku":"35640","price":85.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/799e6d3648bdc789b79e091e5af342a7.jpg?v=1788702634","url":"https:\/\/voomisupply.com\/products\/harvey-tool-35640-ball-end-mill-0-04-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
