It features a 5\/64 inch (0.078 inch) cutting diameter with a 0.117 inch length of cut and a 1\/8 inch shank diameter. The three-flute, right-hand cutting geometry with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. At 3 inches overall length with a 1.562 inch reach, this single-end tool is suited for extended-reach applications where clearance is limited. The bright, uncoated finish makes it compatible with a range of workpiece materials and cutting fluids.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for CNC machining centers, manual mills, and high-speed spindle setups where small-diameter precision cutting is required. Its extended reach geometry makes it well suited for slotting, profiling, and pocket milling in confined geometries or deep features. The centercutting capability allows direct plunge entry into the workpiece. Machinists, tool-and-die makers, and CNC programmers working in job shops or precision manufacturing environments are the primary users of this tool.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance at small diameters\u003c\/li\u003e\n\u003cli\u003eThree right-hand flutes with 30-degree helix for balanced chip load and surface finish\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling\u003c\/li\u003e\n\u003cli\u003eExtended reach at 1.562 inches provides clearance in deep or confined features\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for use with a wide range of materials and coolants\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with 1\/8 inch shank for standard collet and end mill holder fitment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide square end mill for use in standard 1\/8 inch collets, end mill holders, and shrink-fit tooling systems on CNC and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully powered down and at rest before changing tooling. Secure the shank to the full recommended engagement depth in the collet or holder and torque the retention system per the tool holder manufacturer specifications. At this diameter, runout control is critical — verify tool runout with a dial indicator before beginning the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/64 inch (0.078 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.117 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 1.562 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\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\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\u003eEnd Type\u003c\/strong\u003e: Single End\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: 58378\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51753113977138,"sku":"58378","price":96.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a7e6f269fc9ca32ea699f18f99445b05_cc07a291-c633-4ef0-9933-35b574b93c8b.jpg?v=1788932937","url":"https:\/\/voomisupply.com\/products\/harvey-tool-58378-square-end-mill-5-64-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
