With a 0.078 inch (5\/64 inch) mill diameter, a 0.234 inch length of cut, and a 3-flute helical geometry, this tool handles both roughing and finishing operations in a single pass. The 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces in tight-tolerance work. At 1.5 inches overall length with a 0.125 inch straight-cylindrical shank, this is a miniature-series tool built for high-precision machining centers and CNC mills requiring small-diameter toolpaths.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling steel, stainless steel, cast iron, and non-ferrous metals in applications where fine detail and close tolerances are required. Typical use cases include die and mold work, prototype machining, and finish passes on contoured surfaces. The uncoated bright finish makes it appropriate for applications where coating interaction with the workpiece material is a concern, or where regrinding is anticipated. Single-end configuration provides a consistent reference for tool length offset setup.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003e3-flute helical design supports both roughing and finishing in a single tool\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes chip evacuation and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003e0.039 inch nose radius delivers accurate ball-end profile for contoured surfaces\u003c\/li\u003e\n\u003cli\u003eUncoated bright finish compatible with a wide range of workpiece materials including non-ferrous metals\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard collet chucks and end mill holders\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 manual mills equipped with standard 1\/8 inch collet or end mill holder systems.

Verify collet and holder runout before use, as runout at small diameters significantly affects tool life and surface finish. Do not exceed manufacturer-recommended speeds and feeds for the workpiece material and depth of cut. Inspect the tool for chipping or wear before each setup.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.078 inches (5\/64 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.234 inches (15\/64 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 (1\/8 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\u003eNose Radius\u003c\/strong\u003e: 0.039 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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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\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\u003eWeight\u003c\/strong\u003e: 0.01 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: 835978\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51749414961458,"sku":"835978","price":48.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/360dd0b265375eea331626520b6656d0_7ff93d43-31aa-42cd-ba38-d07b1653323c.jpg?v=1788905790","url":"https:\/\/voomisupply.com\/products\/harvey-tool-835978-ball-end-mill-0-078-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
