It features a 1\/2-inch cutting diameter, a 5\/8-inch length of cut, and a 37-degree right-hand helix angle that promotes efficient chip evacuation and smooth cutting action. The tool is coated with zirconium nitride (ZrN), which adds surface hardness and wear resistance for extended tool life in demanding machining environments. Machined from micrograin carbide stock, it holds tight tolerances and is center-cutting capable, allowing plunge entry directly into the workpiece.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling operations in machine shops, production environments, and toolroom applications. It is used in vertical and horizontal CNC machining centers as well as manual knee mills. The 1\/2-inch shank diameter fits standard ER and shell mill collet systems. Typical applications include slotting, profiling, and peripheral milling in steel, alloy, stainless, and non-ferrous materials where a short-reach, rigid 3-flute geometry is preferred.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-inch cutting diameter with mill diameter tolerance of +0.000 \/ -0.005 inches\u003c\/li\u003e\n  \u003cli\u003e37-degree right-hand spiral helix for efficient chip flow and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eZrN (zirconium nitride) coating for improved wear resistance and surface hardness\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting geometry allows direct plunge milling without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide construction for rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003eSingle-end design with 3-inch overall length and 1\/2-inch shank diameter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-shank replacement end mill compatible with 1\/2-inch collet chucks, ER collet systems, and end mill holders used on CNC machining centers and manual milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the holder. Seat the shank to the recommended gauge depth for the collet or holder in use and torque the retention mechanism according to the toolholder manufacturer specifications. Inspect the cutting edges and coating for chips or wear before each use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5000 inches (1\/2 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.625 inches (5\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5000 inches (1\/2 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 37 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting 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\u003c\/strong\u003e: ZrN (Zirconium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.005 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: 0.3 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 314818\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51741203497266,"sku":"314818","price":114.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/897e860400241f7108b72e664a551aa4.jpg?v=1788830014","url":"https:\/\/voomisupply.com\/products\/accupro-314818-square-end-mill-1-2-in-3-flute-carbide-zrn","provider":"Voomi Supply","version":"1.0","type":"link"}
