It features a 5\/32-inch (0.1562-inch) cutting diameter with a 5\/16-inch (0.3125-inch) length of cut and a 37-degree helix angle that promotes efficient chip evacuation and smooth cutting action. The three-flute geometry balances chip clearance with edge strength, making it well suited for slotting, profiling, and peripheral milling in tighter tolerances. Machinists and toolroom technicians working on CNC mills or manual knee mills will find this end mill sized for detail work and close-tolerance cuts.\u003c\/p\u003e\u003cp\u003eThis end mill is appropriate for use in light to medium-duty milling applications where a small-diameter, high-rigidity tool is required. The bright\/uncoated finish makes it a practical choice for non-ferrous metals, aluminum alloys, brass, and similar materials where coating adhesion is not a primary concern. The right-hand cutting and right-hand flute direction are standard for conventional CNC milling spindle rotation. The 3\/16-inch shank diameter fits standard collet systems commonly used in CNC machining centers and manual milling equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/32-inch (0.1562-inch) cutting diameter with a mill diameter tolerance of +0.000 \/ -0.005 inches\u003c\/li\u003e\n\u003cli\u003e3\/16-inch (0.1875-inch) shank diameter with tolerance of +0.0001 \/ -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e37-degree helix angle for efficient chip evacuation during profiling and slotting\u003c\/li\u003e\n\u003cli\u003eThree-flute spiral design balances chip clearance with cutting edge strength\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance in small-diameter applications\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suitable for non-ferrous and general-purpose milling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide square end mill replacement suitable for use in standard collet toolholding systems accepting a 3\/16-inch shank diameter on CNC machining centers and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician familiar with collet and end mill toolholding systems. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet to the recommended minimum engagement depth and torque the collet nut per the toolholder manufacturer specification. Inspect the cutting edges for chipping or runout before beginning a new operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/32 inch (0.1562 inches)\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\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\u003eLength of Cut\u003c\/strong\u003e: 5\/16 inch (0.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 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\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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003ePackage Weight\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: 314491\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732067516722,"sku":"314491","price":52.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cefce5efb7c3d91447fe6143a2831677_1e3ca9b3-153e-4069-8d5a-083a33a74d59.jpg?v=1788738825","url":"https:\/\/voomisupply.com\/products\/accupro-314491-square-end-mill-5-32-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
