With a 0.5 inch cutting diameter and four spiral flutes ground to a 40-degree helix angle, this tool delivers efficient chip evacuation and smooth surface finishes in ferrous and non-ferrous materials. The nACRo coating improves heat resistance and wear life in dry or near-dry cutting conditions. Centercutting geometry allows plunge entry directly into the workpiece. This is a right-hand cut, right-hand flute configuration in a stub-length format, making it a common choice for machinists and tool-and-die shops running CNC mills or manual knee mills.\u003c\/p\u003e\u003cp\u003eThis end mill suits general-purpose milling operations including slotting, profiling, and peripheral cuts where a short, rigid tool is preferred. The stub length reduces deflection in tight setups or shallow-depth applications. It is appropriate for use in production machining, job-shop work, and toolroom operations across ferrous and non-ferrous workpiece materials. No extended-reach or chipbreaker geometry is present, keeping the design straightforward for standard milling tasks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide micrograin substrate for extended tool life and edge retention\u003c\/li\u003e\n\u003cli\u003enACRo coating for improved wear resistance and thermal stability\u003c\/li\u003e\n\u003cli\u003e40-degree spiral helix promotes smooth cutting action and chip flow\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for standard CNC and manual mill spindles\u003c\/li\u003e\n\u003cli\u003eStub length format reduces deflection in shallow-depth applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit cutting tool for standard 0.5 inch collet, shrink-fit, or set-screw tool holders used 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 toolroom professional. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank to the full recommended engagement depth in the holder to minimize runout and prevent pullout during cutting. Verify tool holding torque specifications per the tool holder manufacturer guidelines before commencing the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 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: 40 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 (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: nACRo\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: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.256 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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12179021\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730488000818,"sku":"12179021","price":109.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7aa808a0c258f18cd216e98736619bb7.jpg?v=1788718343","url":"https:\/\/voomisupply.com\/products\/accupro-12179021-square-end-mill-0-5in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
