Built as a single-end tool with a 5\/64-inch (0.0780-inch) cutting diameter and a 5\/8-inch length of cut, it delivers extended reach in a miniature form factor. The 1\/8-inch shank diameter and 2.5-inch overall length make it well-suited for tight-clearance work. Three flutes with a 30-degree helix angle promote efficient chip evacuation and a smooth surface finish. The bright, uncoated finish is appropriate for a wide range of workpiece materials. Licensed machinists and CNC operators install this tool in milling centers and machining cells for fine-detail work.\u003c\/p\u003e\n\u003cp\u003eThis end mill is designed for use on steel, stainless steel, cast iron, aluminum and non-ferrous metals, and CFRP composite materials. Its centercutting geometry allows plunge entry as well as conventional peripheral milling. The miniature diameter makes it a go-to choice for slotting, profiling, and pocketing operations in mold work, die making, aerospace components, and precision part manufacturing where larger tools cannot reach. Right-hand cut and right-hand flute direction are standard for conventional CNC mill setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance at small diameters\u003c\/li\u003e\n  \u003cli\u003e5\/64-inch (0.0780-inch) cutting diameter with 5\/8-inch length of cut for extended reach in miniature applications\u003c\/li\u003e\n  \u003cli\u003eThree-flute design with 30-degree helix angle promotes chip flow and finish quality\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable across steel, stainless, cast iron, aluminum, non-ferrous, and CFRP materials\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute — compatible with standard CNC milling spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style miniature square end mill for use in CNC machining centers and manual mills equipped with 1\/8-inch collets or equivalent toolholding systems accepting a 0.1250-inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety protocols and machine tool manufacturer guidelines. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before inserting or removing the end mill from the collet or toolholder. Verify runout with a dial indicator after seating the tool, as excessive runout at small diameters accelerates tool wear and can cause breakage. Follow the tool manufacturer and material guidelines for feeds, speeds, and depth of cut when programming or setting up the operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/64 inch (0.0780 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 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\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: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Aluminum and Non-Ferrous, CFRP Materials\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: 33678\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51748643569970,"sku":"33678","price":60.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/32f03fcaa1ec94a4e176dd94797e81e6_07f05077-2a4c-449a-b47a-ff4e9188adee.jpg?v=1788896109","url":"https:\/\/voomisupply.com\/products\/harvey-tool-33678-square-end-mill-5-64-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
