With a 3\/8 inch cutting diameter and a 3 inch length of cut, this tool handles deep-reach profiling, slotting, and peripheral milling where standard-length tools fall short. The 6 inch overall length places it in the extra-long category, giving machinists access to recessed features and deep pockets. Three spiral flutes with a 40-degree helix angle promote efficient chip evacuation and smooth cutting action. The micrograin carbide substrate supports edge retention in demanding applications. This tool is installed by machinists and CNC operators working in job shops, toolrooms, and production environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits applications requiring extended reach in ferrous and non-ferrous materials, including steel, aluminum, and engineering plastics. The centercutting geometry allows the tool to plunge directly into workpiece material, enabling full-slot milling as well as ramping and helical interpolation. Right-hand cut and right-hand flute orientation match standard spindle rotation on vertical and horizontal machining centers. The uncoated finish makes it a direct-use option or a suitable base for shops that apply their own coatings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3 inch length of cut supports deep-pocket and extended-reach milling operations\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes chip flow and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge entry and helical interpolation\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide construction provides edge retention and rigidity\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute for standard CNC machining center compatibility\u003c\/li\u003e\n  \u003cli\u003eSpiral flute geometry with no chipbreaker for consistent surface finish in finishing passes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide square end mill for CNC machining centers and manual mills accepting a 3\/8 inch straight shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or CNC setup technicians. The spindle must be fully stopped and the machine placed in an e-stop or lockout state before changing tooling. Secure the 3\/8 inch shank in a collet chuck or end mill holder to the manufacturer-specified clamping torque for that holder type. Inspect the shank and holder bore for chips or burrs before seating the tool, as contamination affects runout and tool life.\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 inch (0.3750 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\u003c\/strong\u003e: 3 inches (3.0000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches (6.0000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003c\/strong\u003e: Uncoated\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: Extra Long\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: 0.4 pounds\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: 12182316\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51748484415794,"sku":"12182316","price":94.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fd572a3259321e40fed11d4fed967ba1.jpg?v=1788894288","url":"https:\/\/voomisupply.com\/products\/accupro-12182316-square-end-mill-3-8-in-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
