With a 5\/64 inch (0.0780 inch decimal) mill diameter and a 0.117 inch length of cut, this is a small-diameter tool built for tight-tolerance work in confined areas. The 3-flute geometry balances chip evacuation with tool rigidity at this size range. A 30-degree helix angle promotes smooth cutting action and helps reduce deflection. The bright, uncoated finish makes this tool suitable for a wide range of work materials where a coating is not required. Licensed machinists and toolroom technicians are the primary users of this end mill.\u003c\/p\u003e\u003cp\u003eThis end mill fits residential toolroom, job shop, and production machining environments where small-diameter, high-precision cuts are required. The 0.125 inch (1\/8 inch) shank diameter is compatible with standard collet systems. With a 2.5 inch overall length and an extended reach of 0.8 inch, this tool can access recessed features and pockets that standard-length end mills cannot reach. It is a single-end, right-hand cut, right-hand flute configuration suited for conventional CNC machining centers and manual mills with appropriate collet chucks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/64 inch (0.0780 inch) mill diameter for fine, small-diameter milling operations\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance at small diameters\u003c\/li\u003e\n\u003cli\u003e3-flute design balances chip clearance and core strength\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle for smooth cutting and reduced deflection\u003c\/li\u003e\n\u003cli\u003eExtended reach of 0.8 inch allows access to deep or recessed features\u003c\/li\u003e\n\u003cli\u003eCentercutting capable, permitting plunge entry into the workpiece\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 1\/8 inch collet systems on CNC machining centers and manual milling machines that accept right-hand cut, solid carbide end mills in the small-diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or toolroom technician using an appropriate collet or end mill holder sized to the 0.125 inch shank. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank to the full recommended engagement depth in the collet to minimize runout and prevent pullout during cutting. At small diameters, excessive overhang beyond the stated reach length increases deflection risk and should be avoided.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/64 inch (0.0780 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.117 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.125 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.8 inch\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\u003eCentercutting\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\u003eConfiguration\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: 982178\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51744939442482,"sku":"982178","price":75.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9cf084c8d4615dcb426071d44e4f84ff_6edb0a70-27cf-4f5a-91ab-aa44d56b27b7.jpg?v=1788862471","url":"https:\/\/voomisupply.com\/products\/harvey-tool-982178-square-end-mill-5-64-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
