With a 5\/64-inch (0.078 inch) mill diameter and five flutes, this tool delivers smooth material removal and improved chip evacuation compared to standard four-flute designs. The AlTiN Nano coating provides elevated heat resistance and surface hardness, extending tool life in difficult-to-machine materials. A variable helix angle reduces harmonic vibration and chatter, contributing to better finish quality and dimensional accuracy. This end mill is suited for machinists and tooling professionals working in CNC milling environments where tight tolerances are required.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in CNC machining centers and manual mills where small-diameter, high-precision cutting is required. The 5\/64-inch diameter and 0.475-inch length of cut make it well suited for finishing passes, slot milling, and detail work in ferrous and non-ferrous materials, as well as hardened steels where the AlTiN Nano coating provides thermal protection. The 1\/8-inch shank diameter is compatible with standard small-bore collets and tool holders. Right-hand cutting and right-hand flute direction are standard configurations for conventional CNC setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/64-inch (0.078 inch) mill diameter for fine detail and small-slot machining\u003c\/li\u003e\n\u003cli\u003eFive-flute geometry improves chip flow and surface finish compared to fewer-flute alternatives\u003c\/li\u003e\n\u003cli\u003eAlTiN Nano coating enhances hardness and heat resistance for extended tool life in tough materials\u003c\/li\u003e\n\u003cli\u003eVariable helix design reduces vibration and chatter during cutting\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute — standard orientation for most CNC setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 1\/8-inch collets and small-bore tool holders in CNC machining centers and manual milling machines. Compatible with applications requiring an end mill in the 0.3000 to 0.5000 inch length-of-cut range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and machine is powered down before changing tooling. Secure the 1\/8-inch shank in a clean, properly sized collet or tool holder to the manufacturer-specified clamping method — contamination or improper seating will reduce runout performance and shorten tool life. Note that this end mill is not centercutting and should not be used for direct plunge operations.\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: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.475 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches (2-1\/2 inches)\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN Nano\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: No\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut Range\u003c\/strong\u003e: 0.3000 to 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.03 inches L x 0.32 inches W x 0.32 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 778378-C6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51732562215218,"sku":"778378-C6","price":91.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a878c17c3de258c011844bb4d71258c4_03fb1d24-9566-4cf2-865a-554b930efa5a.jpg?v=1788744472","url":"https:\/\/voomisupply.com\/products\/harvey-tool-778378-c6-square-end-mill-5-64-in-5-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
