With a 5\/64 inch (0.078 inch) cutting diameter and a 3 mm (0.118 inch) length of cut, this end mill is built for fine detail work and tight-tolerance slots, pockets, and profiles. The three-flute geometry balances chip evacuation with cutting edge count, making it well-suited for both ferrous and non-ferrous materials. The bright uncoated finish allows for easy wear inspection and works across a range of general-purpose applications without added coating complexity.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for CNC machining centers and manual mills where small-diameter, high-precision cutting is required. The 1\/8 inch shank diameter fits standard collets and tool holders commonly found in production and job shop environments. With a 2.5 inch overall length and a 5\/8 inch reach length, the 34678 provides extended reach capability for accessing recessed features without sacrificing rigidity. It is a single-end design, meaning the tool is replaced rather than flipped when the cutting edge is spent.\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\u003e5\/64 inch (0.078 inch) cutting diameter for fine-detail slot and pocket work\u003c\/li\u003e\n\u003cli\u003eThree right-hand flutes with right-hand cutting direction for efficient chip removal\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle balances cutting forces and surface finish quality\u003c\/li\u003e\n\u003cli\u003eExtended reach design with 5\/8 inch reach length for access to recessed features\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for general-purpose milling across multiple material types\u003c\/li\u003e\n\u003cli\u003eCentercutting capability allows plunge entry directly into the workpiece\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and general-use solid carbide square end mill compatible with standard 1\/8 inch collets and tool holders on CNC machining centers and manual mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the 1\/8 inch shank fully in the collet or tool holder to the recommended grip length before torquing the retention nut. Confirm runout with a dial indicator before beginning a production cut, as small-diameter end mills are sensitive to collet wear and improper seating.\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\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\u003eLength of Cut\u003c\/strong\u003e: 3 mm (0.118 inch)\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\u003eReach Length\u003c\/strong\u003e: 5\/8 inch (0.625 inch)\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\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: 0.2 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: 34678\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51733128642866,"sku":"34678","price":73.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c05da99c098c6ea978782ee78719a9ac_ccb86a98-4861-4fc8-bc55-610067a438ce.jpg?v=1788751609","url":"https:\/\/voomisupply.com\/products\/harvey-tool-34678-square-end-mill-5-64-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
