Built from micrograin carbide stock, it delivers the hardness and edge retention needed for ferrous and non-ferrous materials. The 4-flute, spiral geometry with a 40-degree helix angle promotes efficient chip evacuation and smooth surface finishes. At 0.375 inches in diameter with a 0.875-inch length of cut, this end mill suits slotting, profiling, and peripheral milling operations. The uncoated finish makes it a reliable general-purpose option where coating is not required. Installed by CNC machinists and manual mill operators alike.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for production and job-shop environments running vertical or horizontal milling machines and CNC machining centers. Its centercutting capability allows plunge entry directly into the workpiece without a pre-drilled pilot hole, adding flexibility for complex toolpaths. The right-hand cut and right-hand flute configuration is standard for conventional and climb milling setups. With a 0.375-inch shank diameter, it seats directly in standard ER or end mill holders sized for 3\/8-inch tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for edge hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003e4-flute spiral geometry with 40-degree helix angle for efficient chip flow and surface finish\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without pilot hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for standard milling machine setups\u003c\/li\u003e\n\u003cli\u003eUncoated  -  suitable for general-purpose use and re-sharpening\u003c\/li\u003e\n\u003cli\u003eMatched shank and cutting diameter at 0.375 inches for straightforward tool holding\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use end mill for milling machines and CNC machining centers accepting 3\/8-inch shank tooling in standard ER collets or end mill holders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed by a qualified machinist with the spindle fully powered down and locked out per shop safety procedures. Verify tool holder runout before operation, as excessive runout accelerates edge wear and degrades surface finish. Tighten collet or set-screw holders to the tool holder manufacturer's specified procedure. Confirm cutting parameters  -  speed, feed, and depth of cut  -  are appropriate for the workpiece material before engaging the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.875 inches (7\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\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\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\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.001 \/ -0.000 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: 0.139 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: 12177084\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51739978137906,"sku":"12177084","price":77.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/caf9e08c851fdbc6314f8f782b9ac116.jpg?v=1788820981","url":"https:\/\/voomisupply.com\/products\/accupro-12177084-square-end-mill-3-8-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
