With a 5\/64 inch (0.0781 inch) mill diameter and a 3\/16 inch (0.1875 inch) length of cut, this tool is built for tight-tolerance work in confined spaces. The micrograin carbide substrate paired with an AlTiN finish delivers heat resistance and edge retention at elevated cutting speeds. Four spiral flutes with a 30-degree helix angle promote efficient chip evacuation and smooth surface finishes. Centercutting capability allows plunge entry without a pre-drilled pilot hole. This end mill is installed and operated by machinists, tool-and-die makers, and CNC technicians.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits general-purpose milling, slotting, profiling, and pocket milling in ferrous and non-ferrous metals, as well as hardened steels and exotic alloys where AlTiN coating provides thermal protection. The 1\/8 inch shank diameter fits standard ER collet chucks, end mill holders, and milling machine spindles. The regular-length geometry and 1-1\/2 inch overall length keep deflection low in high-speed CNC machining centers and manual mills alike. Typical applications include die and mold work, prototype machining, and precision component manufacturing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eAlTiN finish for elevated heat resistance and extended tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e4 spiral flutes with 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute configuration for standard spindle operation\u003c\/li\u003e\n  \u003cli\u003eRegular length geometry minimizes deflection in precision applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or upgrade for 1\/8 inch shank square end mills in standard ER collet chucks and end mill holders used on CNC machining centers and manual knee mills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC technician. Ensure the machine spindle is fully de-energized and at a complete stop before changing tooling. Use a calibrated torque wrench when tightening the collet nut to the chuck specification. Confirm shank seating depth and runout with a dial indicator before beginning a cut to avoid tool pull-out or premature edge failure.\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 (0.0781 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/16 inch (0.1875 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-1\/2 inch (1.5000 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: AlTiN\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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3 inches L x 0.3 inches W x 0.3 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 750427\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51733656797490,"sku":"750427","price":38.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/83238f0457205b058d19162e1f3464a6.jpg?v=1788757596","url":"https:\/\/voomisupply.com\/products\/hertel-750427-square-end-mill-5-64-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
