With a 5\/64 inch (0.0780 inch) cutting diameter and 7 flutes, this end mill delivers smooth surface finishes and efficient chip evacuation in tight-tolerance applications. The AlTiN coating provides heat resistance and wear protection, making it well suited for hard metals and abrasive materials at elevated cutting speeds. A variable helix design reduces harmonic vibration and chatter during the cut. This tool is installed and run by machinists and CNC operators in production and job-shop settings.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in CNC machining centers and manual mills where small-diameter, multi-flute tooling is required. The 5\/64 inch diameter and 15\/64 inch length of cut make it appropriate for slotting, profiling, and contouring in confined areas or on small features. The 1\/8 inch shank diameter fits standard collets and tool holders common in both vertical and horizontal milling setups. Right-hand cutting and right-hand flute direction are standard for conventional and climb milling operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and extended tool life\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating improves heat resistance and wear performance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e7-flute geometry increases feed rates and improves finish quality at small diameters\u003c\/li\u003e\n  \u003cli\u003eVariable helix angle reduces chatter and vibration during cutting\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction for standard milling operations\u003c\/li\u003e\n  \u003cli\u003e1\/8 inch shank diameter fits widely available collets and tool holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement-style solid carbide square end mill for CNC and manual milling machines accepting a 1\/8 inch shank diameter collet or tool holder.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed by machinists and CNC operators. Ensure the spindle is fully powered down and at rest before changing tooling. Seat the shank fully and evenly in a clean, undamaged collet to the recommended engagement depth per the tool holder manufacturer. Do not exceed the tool's rated length-of-cut range of 0.2000 to 0.3000 inches when programming axial depth of cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eNumber of Flutes\u003c\/strong\u003e: 7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 15\/64 inch (0.234 inch)\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 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\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: Yes (41 degree)\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: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut Range\u003c\/strong\u003e: 0.2000 to 0.3000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 57878-C6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51748119216434,"sku":"57878-C6","price":72.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f0b206c08658414209a6c13a8955e33d_cb6c36dd-0613-4d8e-8f35-3184b513d444.jpg?v=1788889292","url":"https:\/\/voomisupply.com\/products\/harvey-tool-57878-c6-square-end-mill-5-64-in-7-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
