It measures 0.625 inches in diameter with a 3.25-inch length of cut and a 6-inch overall length, making it well-suited for deep-reach slotting, profiling, and contouring applications. The three-flute geometry balances chip evacuation with rigidity, while the ZrN (zirconium nitride) coating reduces friction and extends tool life in ferrous and non-ferrous materials. Micrograin carbide construction provides consistent edge integrity under demanding feed rates. Licensed machinists, CNC programmers, and toolroom technicians are the primary users of this end mill.\u003c\/p\u003e\n\u003cp\u003eThis end mill fits standard CNC machining centers, vertical mills, and manual knee mills equipped with a 5\/8-inch collet or end mill holder. The centercutting design allows plunge entry as well as conventional peripheral cutting. Right-hand cut and right-hand spiral flute configuration make it compatible with standard spindle rotation on the vast majority of production and toolroom equipment. The 37-degree helix angle promotes smooth chip flow and reduced cutting forces, which is beneficial when machining aluminum alloys, stainless steels, and medium-carbon steels.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for extended edge life and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eZrN coating reduces friction and heat buildup at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e37-degree helix angle promotes efficient chip evacuation and lower cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting design enables both plunge and peripheral entry\u003c\/li\u003e\n  \u003cli\u003eThree-flute geometry balances rigidity with chip clearance in medium to high feed-rate applications\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute for compatibility with standard CNC and manual spindles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in 5\/8-inch collets or end mill holders on CNC machining centers, vertical mills, and toolroom equipment requiring a standard straight-shank solid carbide square end mill.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified machinists or CNC technicians following shop safety protocols. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank fully into the collet or holder to the recommended grip depth to prevent pullout under load. Verify runout with a dial indicator before beginning cuts, particularly in tight-tolerance applications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.625 inches (5\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3.25 inches (3-1\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.625 inches (5\/8 inches)\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\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 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\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\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\u003eWeight\u003c\/strong\u003e: 0.7 pounds\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: 314960\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51753898017074,"sku":"314960","price":336.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/708512c97bf627cd0da9d6667683773a.jpg?v=1788941892","url":"https:\/\/voomisupply.com\/products\/accupro-314960-square-end-mill-5-8-inch-3-flute-carbide-zrn","provider":"Voomi Supply","version":"1.0","type":"link"}
