Built from micrograin solid carbide, this tool delivers rigidity and wear resistance suited to demanding CNC and manual milling applications. The 0.5 inch diameter cutting end features a 3-flute spiral geometry with a 37-degree right-hand helix, optimized for chip evacuation and surface finish quality. A zirconium nitride (ZrN) coating reduces friction and extends tool life in ferrous and non-ferrous materials. This end mill is a standard choice for machinists running finishing passes, contour milling, and 3D profiling operations.\u003c\/p\u003e\u003cp\u003eThe 315292 is suited for general-purpose machining centers and manual knee mills where a 0.5 inch shank is the standard interface. The 2 inch length of cut (LOC) accommodates moderate-depth pocketing and contouring work. With a 4 inch overall length (OAL), the tool provides adequate reach without sacrificing stiffness. Right-hand cutting direction matches standard CNC spindle rotation. This tool is typically selected for production and job-shop environments where consistent carbide performance is required on a variety of workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for hardness and edge retention\u003c\/li\u003e\n\u003cli\u003eZrN coating reduces friction and extends tool life in ferrous and non-ferrous cuts\u003c\/li\u003e\n\u003cli\u003e3-flute spiral geometry with 37-degree right-hand helix for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003e2 inch LOC supports moderate-depth pocketing and contour passes\u003c\/li\u003e\n\u003cli\u003eSingle-end design with 0.5 inch shank for standard collet and end mill holder interfaces\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting and flute direction for standard CNC spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard-spec ball end mill for CNC machining centers and manual mills accepting a 0.5 inch round shank end mill holder or collet system.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer's toolholding specifications. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank to the full recommended engagement depth in the collet or end mill holder and torque the retention hardware per the holder manufacturer's specification. Verify runout with a dial indicator before beginning a cut.\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: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\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\u003eHelix Angle\u003c\/strong\u003e: 37 degrees\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\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\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\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: 0.5 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: 315292\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51729626759474,"sku":"315292","price":204.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/56324ad5b3becc19488475cf5c04d793.jpg?v=1788706911","url":"https:\/\/voomisupply.com\/products\/accupro-315292-ball-end-mill-1-2-in-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
