Built from micrograin carbide stock and finished with a ZrN (zirconium nitride) coating, this tool delivers extended wear life and improved chip evacuation compared to uncoated alternatives. It features a 5\/8 inch cutting diameter, a 3\/4 inch length of cut, and a 45-degree spiral helix angle that promotes efficient chip flow and reduces cutting forces. Centercutting geometry allows the tool to plunge directly into workpiece material. The 5\/8 inch shank diameter matches the cutting diameter for straightforward toolholder setup in standard collet chucks or end mill holders.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for general-purpose and finish milling of ferrous and non-ferrous metals, alloys, and hard plastics. The right-hand cut and right-hand flute configuration is standard for conventional CNC machining centers and manual knee mills. With a 6 inch overall length, it provides additional reach for deeper setups, stepped workpieces, or fixtures where standard-length tools cannot access the cut zone. Machinists, tool and die makers, and job shop operators working in production or prototype environments are the primary users of this tool.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance in demanding cuts\u003c\/li\u003e\n\u003cli\u003eZrN coating reduces friction and extends tool life in steel and stainless applications\u003c\/li\u003e\n\u003cli\u003e45-degree helix angle promotes smooth chip evacuation and reduces chatter\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without pre-drilled pilot holes\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute — standard orientation for CNC and manual mills\u003c\/li\u003e\n\u003cli\u003e6 inch overall length provides extended reach for deep or restricted setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 5\/8 inch collet chucks, end mill holders, or hydraulic toolholders on CNC machining centers and manual milling machines accepting 5\/8 inch shank tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom professional. Ensure the machine spindle is fully stopped and power is locked out before inserting or removing the tool. Seat the shank to the recommended insertion depth in the toolholder — avoid gripping on the fluted section. Verify runout with a dial indicator before cutting to prevent premature tool wear or workpiece damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.625 inches (5\/8 inch)\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.75 inches (3\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut Range\u003c\/strong\u003e: 0.700 - 0.800 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.625 inches (5\/8 inch)\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\u003eOverall Length\u003c\/strong\u003e: 6 inches\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: ZrN (Zirconium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 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\u003eExtended Reach\u003c\/strong\u003e: No\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\u003eWeight\u003c\/strong\u003e: 0.7 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 314039\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730106319154,"sku":"314039","price":281.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dcba2a97f055701127f5dcc87ef0e114.jpg?v=1788711824","url":"https:\/\/voomisupply.com\/products\/accupro-314039-square-end-mill-5-8-inch-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
