It features a 5\/64-inch (0.0780-inch) mill diameter and a 15\/64-inch (0.234-inch) length of cut, making it well suited for fine detail work in tight spaces. The 2-flute, right-hand spiral configuration with a 30-degree helix angle promotes efficient chip evacuation. A 1\/2-inch reach length and long-length designation give this tool extended access into workpiece features. The bright, uncoated finish preserves the as-ground carbide edge for general-purpose use across a range of materials. Installation is performed by licensed machinists and CNC programmers.\u003c\/p\u003e\u003cp\u003eThis end mill is used in vertical machining centers, CNC mills, and manual milling machines where small-diameter, high-precision cutting is required. The long reach and extended neck geometry allow access to deep pockets, slots, and profiling operations that standard-length tools cannot reach. It is centercutting, meaning it can plunge directly into the workpiece. Typical materials include aluminum, brass, plastics, and softer steels. The single-end design means the tool is replaced rather than reversed when the cutting edge is worn.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in precision milling\u003c\/li\u003e\n\u003cli\u003e2-flute right-hand spiral with 30-degree helix for effective chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting capability allows direct plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eExtended reach with 1\/2-inch reach length and long-length designation for deep-feature access\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for general-purpose machining across common materials\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills accepting a 1\/8-inch straight shank; no specific OEM model compatibility was provided in the product data.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed by qualified machinists or CNC setup technicians. The machine spindle must be fully stopped and locked out before changing tooling. The 1\/8-inch shank requires a collet or end mill holder of matching diameter, properly torqued per the machine manufacturer's specifications. Avoid side-loading the tool beyond rated depth-of-cut parameters, as the small diameter makes the tool susceptible to deflection and breakage at excessive feed rates.\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 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 15\/64 inch (0.234 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-1\/2 inches (1.5 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\u003eReach Length\u003c\/strong\u003e: 1\/2 inch (0.5 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\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\u003eLength Type\u003c\/strong\u003e: Long\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\u003eWeight\u003c\/strong\u003e: 0.08 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: 76278\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51733221998898,"sku":"76278","price":72.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5604eb7cd5fb6161fa95c984900a7a44.jpg?v=1788752945","url":"https:\/\/voomisupply.com\/products\/harvey-tool-76278-square-end-mill-5-64-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
