With a 0.04 inch cutting diameter and a 0.06 inch length of cut, this tool is built for fine detail work in tight geometries. The 3-flute, right-hand spiral design with a 30-degree helix angle promotes efficient chip evacuation while maintaining a clean edge finish. At 2.5 inches overall length with a 1\/8 inch shank diameter, this single-end mill fits standard collet toolholders. The bright uncoated finish makes it suited for materials where coating adhesion or heat buildup is a concern. Licensed machinists and CNC operators install this tool in production and prototype environments.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for CNC milling centers and manual knee mills where small-diameter precision cutting is required. The extended reach configuration, with a 0.325 inch reach length, allows access to features in deeper pockets or recessed areas that standard-length end mills cannot reach. The centercutting capability supports plunge entry in addition to peripheral and slot milling operations. Typical applications include finishing passes on small features, slot milling, and profiling in aerospace, medical device, and precision instrument manufacturing.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.04 inch cutting diameter for fine detail and small-feature milling\u003c\/li\u003e\n\u003cli\u003e3-flute solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003e30-degree right-hand helix with right-hand cutting direction for efficient chip flow\u003c\/li\u003e\n\u003cli\u003eExtended reach at 0.325 inches for access to deeper pocket features\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge milling without a pre-drilled entry point\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for non-ferrous metals and materials sensitive to coated tooling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide square end mill compatible with standard 1\/8 inch collet toolholders used in CNC machining centers and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator familiar with small-diameter tooling. Secure the 1\/8 inch shank in a properly sized, clean collet or end mill holder and verify runout before cutting. Small-diameter carbide end mills are brittle and highly sensitive to side loading, tool overhang, and improper feed rates. Always confirm spindle speed and feed parameters match the workpiece material before engaging the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.04 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.06 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\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.325 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\u003eFlute Type\u003c\/strong\u003e: Spiral\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\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\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\u003eLength Type\u003c\/strong\u003e: Long\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: 0.25 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 34640\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51727564833074,"sku":"34640","price":75.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c05da99c098c6ea978782ee78719a9ac_cca28745-8fa2-4bcf-b7ae-632f3b29ca9d.jpg?v=1788679443","url":"https:\/\/voomisupply.com\/products\/harvey-tool-34640-square-end-mill-0-04-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
