Built from micrograin solid carbide, it delivers consistent cutting performance and edge retention under demanding conditions. The mill measures 1\/2 inch in diameter with a 5\/8 inch length of cut and a 3-inch overall length. A 37-degree helix angle promotes efficient chip evacuation and smooth cutting action. The zirconium nitride (ZrN) coating reduces friction and extends tool life across a range of workpiece materials. Machinists and tool-and-die professionals install this end mill in CNC machining centers and manual mills for contouring, slotting, and finishing passes.\u003c\/p\u003e\u003cp\u003eThis ball end mill suits applications requiring a full-radius cutting profile, including 3D contouring, cavity milling, and blending operations on molds, dies, and complex part geometries. The 3-flute configuration balances material removal rate with chip clearance, making it effective on aluminum, steel, and hardened materials. The right-hand cut and right-hand spiral flute geometry are standard for conventional and climb milling on vertical and horizontal machining centers. The 1\/2 inch shank diameter fits standard ER collets and end mill holders commonly found in production and job-shop environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for high rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eZrN coating reduces friction and extends tool life\u003c\/li\u003e\n\u003cli\u003e37-degree helix angle promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003e3-flute design balances chip clearance with cutting efficiency\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand spiral for standard machining setups\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration for direct holder mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard-production ball end mill fitting any tool holder or collet chuck sized for a 1\/2 inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is 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. Seat the shank fully into the collet or end mill holder and torque the retention nut to the tool holder manufacturer's specification. Verify runout with a dial indicator before beginning production cuts to avoid premature tool wear or part rejection.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/8 inches\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: 1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\u003eHelix Angle\u003c\/strong\u003e: 37 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: ZrN\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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\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: 315299\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51745889091890,"sku":"315299","price":152.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d51b6a75f9ea66224a9013190e87500.jpg?v=1788865578","url":"https:\/\/voomisupply.com\/products\/accupro-315299-ball-end-mill-1-2-in-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
