Built from micrograin carbide and coated with a nACRo finish, this stub-length tool offers improved wear resistance and thermal stability in demanding cutting environments. It features a 5\/16 inch cutting diameter, a 1\/2 inch length of cut, and a 40-degree helix angle with a 4-flute spiral configuration. The centercutting geometry allows for plunge entry as well as conventional peripheral milling. This end mill is installed and operated by machinists and tooling technicians working on CNC machining centers and manual knee mills.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for high-speed finishing and semi-finishing passes in ferrous and non-ferrous materials where tool life and surface finish quality matter. The stub length format reduces overhang and improves rigidity, making it appropriate for shallow-to-moderate depth-of-cut applications in tight-tolerance work. The nACRo coating performs well in dry or minimal-lubrication cutting scenarios. 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\u003eSolid micrograin carbide construction for hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003enACRo coating for extended tool life in dry and semi-dry cutting\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes smooth chip evacuation and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting design enables plunge milling entry\u003c\/li\u003e\n\u003cli\u003eStub length format increases rigidity and reduces deflection\u003c\/li\u003e\n\u003cli\u003e4-flute spiral configuration for efficient material removal and improved finish\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement-style solid carbide square end mill for standard 5\/16 inch collet or end mill holder tooling systems on CNC machining centers and conventional vertical mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis end mill is installed by machinists using a compatible 5\/16 inch collet, end mill holder, or set-screw adapter. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Verify shank engagement depth meets the tool holder manufacturer minimum before tightening. Inspect the collet or holder bore for chips or wear before seating the tool.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/2 inch (0.5 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eCoating\/Finish\u003c\/strong\u003e: nACRo\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\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\u003eWeight\u003c\/strong\u003e: 0.08 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: 12179008\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51727403057458,"sku":"12179008","price":57.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/42db8dca57370371090ff90cde3b72af.jpg?v=1788677433","url":"https:\/\/voomisupply.com\/products\/accupro-12179008-square-end-mill-5-16-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
