Built from micrograin carbide and coated with zirconium nitride (ZrN), this tool delivers improved wear resistance and surface finish quality compared to uncoated tooling. It features a 0.5-inch mill diameter, a 2-inch length of cut, and a 45-degree helix angle that promotes efficient chip evacuation and reduced cutting forces. The single-end, two-flute geometry suits slotting, profiling, and contouring tasks where chip clearance is a priority. Machinists and CNC operators in job shops, tool rooms, and production environments are the primary users.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use in vertical and horizontal machining centers as well as manual knee mills where a long-reach tool is required. The 4-inch overall length and 0.5-inch shank diameter make it a practical choice for reaching into deeper cavities or stepped features without sacrificing rigidity. The right-hand cut and right-hand spiral flute direction follow standard conventions for most CNC and manual milling setups. ZrN coating performs well on non-ferrous metals, aluminum alloys, brass, and some plastics, where built-up edge on uncoated tools is a common concern.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.5-inch mill diameter with a tolerance of +0.000 \/ -0.002 inches for consistent fit and finish\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for hardness and edge retention at elevated cutting speeds\u003c\/li\u003e\n\u003cli\u003eZrN (zirconium nitride) coating reduces friction and extends tool life on non-ferrous materials\u003c\/li\u003e\n\u003cli\u003e45-degree helix angle promotes smooth chip flow and reduces chatter in slotting applications\u003c\/li\u003e\n\u003cli\u003e2-inch length of cut with 4-inch overall length classified as long-reach geometry\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable, allowing direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard shank end mill compatible with 1\/2-inch collets, end mill holders, and hydraulic chucks used on CNC machining centers and manual milling machines.

Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully in the holder to the recommended engagement depth per the toolholder manufacturer's specification, and verify runout with a dial indicator before beginning a cut. Do not exceed the tool's rated depth of cut for the material being machined.\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 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\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.0001 \/ -0.0004 inches\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\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: ZrN (Zirconium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin Grade\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\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 313337\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51733123039538,"sku":"313337","price":168.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/52b7450b289c2ad631f04f8d847cae9d.jpg?v=1788751524","url":"https:\/\/voomisupply.com\/products\/accupro-313337-square-end-mill-1-2-in-2-flute-carbide-zrn","provider":"Voomi Supply","version":"1.0","type":"link"}
