Built from micrograin solid carbide, it delivers the rigidity and edge retention required for aggressive cuts in ferrous and non-ferrous materials. The 1\/2 inch cutting diameter pairs with a 37-degree helix angle and spiral flute geometry to promote smooth chip evacuation and reduce chatter. A ZrN (Zirconium Nitride) coating adds surface hardness and heat resistance, extending tool life in demanding applications. The 3-flute configuration balances chip load capacity with cutting speed, making it well suited for both finishing and semi-finishing passes.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in CNC machining centers and manual mills across job shops, tool rooms, and production environments. The 5\/8 inch length of cut handles moderate-depth profiling and contouring work, while the extended reach design — with a 3-3\/8 inch reach length and 6 inch overall length — allows access to deeper workpiece features without requiring a longer-reach holder. Right-hand cutting and right-hand flute direction are standard for conventional CNC setups. It is appropriate for machinists working in aerospace, mold and die, general metalworking, and precision fabrication.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for superior edge retention and rigidity\u003c\/li\u003e\n  \u003cli\u003eZrN coating increases surface hardness and reduces heat buildup during cutting\u003c\/li\u003e\n  \u003cli\u003e37-degree helix angle promotes efficient chip evacuation and smooth surface finish\u003c\/li\u003e\n  \u003cli\u003eExtended reach design with 3-3\/8 inch reach length for deep-feature access\u003c\/li\u003e\n  \u003cli\u003e3-flute spiral geometry balances chip load and cutting speed\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction for standard CNC compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide ball end mill compatible with standard 1\/2 inch tool holders and collet chucks used in CNC and manual milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or CNC operator using an appropriate collet or end mill holder rated for the 1\/2 inch shank diameter. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the tool. Verify runout with a dial indicator after tooling is secured, as excessive runout will accelerate wear and degrade surface finish. Follow the machine manufacturer and tooling supplier recommendations for feeds, speeds, and depth of cut based on workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/8 inch\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: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 3-3\/8 inches (3.3750 inches)\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\u003eEnd Type\u003c\/strong\u003e: Single End\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\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\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: 0.5 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: 315877\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730966642994,"sku":"315877","price":277.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6488da54970023785b43f7e0cd5f8af8.jpg?v=1788725426","url":"https:\/\/voomisupply.com\/products\/accupro-315877-ball-end-mill-1-2-in-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
