With a 0.0781 inch (5\/64 inch) cutting diameter and four right-hand spiral flutes at a 30-degree helix angle, this tool delivers clean, accurate cuts in a compact stub-length profile. The 0.1563 inch length of cut and 0.125 inch shank diameter suit it to close-tolerance slotting, profiling, and peripheral milling. Machined from micrograin carbide, this end mill offers the rigidity and wear resistance needed for demanding production work. It is a double-end design with a bright, uncoated finish and is center-cutting capable.\u003c\/p\u003e\u003cp\u003eThis end mill fits applications where a small-diameter, short-reach cutting tool is required. Its stub-length overall length of 1.5 inches reduces deflection and supports tighter tolerances in CNC machining centers and manual milling machines alike. It is well suited for cutting ferrous and non-ferrous metals, including aluminum, brass, and steel, in job shop and production settings. The right-hand cut and right-hand flute orientation are standard for conventional vertical milling setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0781 inch (5\/64 inch) cutting diameter for small-feature milling\u003c\/li\u003e\n\u003cli\u003eFour right-hand spiral flutes with 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and extended tool life\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows plunge entry\u003c\/li\u003e\n\u003cli\u003eDouble-end configuration maximizes tool value\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suitable for general-purpose machining\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose replacement solid carbide square end mill in OSG Series 424 for use in standard 1\/8 inch collets or end mill holders on CNC and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety procedures. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the 0.125 inch shank securely in a properly sized collet or end mill holder and torque the retention hardware per the machine manufacturer's specifications. Verify runout with an indicator before beginning cuts to protect the small-diameter cutting edge from premature breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.0781 inches (5\/64 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.1563 inches (5\/32 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\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\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDouble End\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 424\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 424-0781\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51727400796466,"sku":"424-0781","price":34.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4231e375cf7ee0ff46206ac8a81225b6.jpg?v=1788677396","url":"https:\/\/voomisupply.com\/products\/osg-424-0781-square-end-mill-0-0781-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
