With a 3\/8-inch cutting diameter, a 1-1\/4-inch length of cut, and a 3-inch overall length, this is a long-length configuration that extends reach in deeper cavities and stepped features. The three-flute geometry paired with a 37-degree helix angle promotes efficient chip evacuation while maintaining surface finish quality. Constructed from micrograin solid carbide, the tool delivers hardness and edge retention suited to demanding cutting conditions. The bright\/uncoated finish is appropriate for use in a range of materials where coating chemistry is not required.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in CNC machining centers, manual mills, and toolroom environments for slotting, profiling, and peripheral milling. The long-length configuration makes it well suited for reaching into deep pockets, tall workpiece features, or setups where a standard-length tool cannot reach. The right-hand cutting and right-hand flute direction are standard for conventional and climb milling on most vertical and horizontal spindles. Machinists and tool-and-die professionals working with ferrous and non-ferrous metals will find this tool applicable across general-purpose material removal tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for superior hardness and edge retention\u003c\/li\u003e\n  \u003cli\u003e37-degree helix angle promotes smooth chip flow and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eThree-flute design balances chip clearance with rigidity in moderate material removal\u003c\/li\u003e\n  \u003cli\u003eLong-length configuration with 1-1\/4 inches LOC on a 3-inch OAL for extended reach\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows plunge entry into workpiece material\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suitable for general-purpose milling without coating requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct tooling selection for 3\/8-inch collet, end mill holder, or hydraulic chuck setups on CNC and manual milling machines requiring a long-length, three-flute square end mill.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists following standard toolholding procedures. Ensure the spindle is fully stopped and the machine is in a safe state before inserting or removing the tool. Seat the 3\/8-inch shank fully into the holder to the recommended gauge line and torque the retention mechanism per the toolholder manufacturer specification. Verify runout with a dial indicator before commencing cutting operations, as excessive runout accelerates edge wear on carbide tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/4 inches (1.25 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: 3\/8 inches (0.375 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\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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003eCentercutting\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\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\u003eWeight\u003c\/strong\u003e: 1.05 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: 314749\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51733708996914,"sku":"314749","price":88.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/36da44062ca939243448b0aa2de0bd3e.jpg?v=1788758622","url":"https:\/\/voomisupply.com\/products\/accupro-314749-square-end-mill-3-8-in-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
