It features a 3\/8 inch cutting diameter, a 1 inch length of cut, and a 2-1\/2 inch overall length. The 6-flute geometry with a 45-degree helix angle improves chip evacuation and surface finish at higher feed rates. Micrograin carbide construction delivers hardness and edge retention superior to cobalt or HSS tooling. This is a centercutting tool, allowing plunge entry as well as conventional peripheral milling. Right-hand cut and right-hand flute configuration matches standard spindle rotation on most CNC machining centers and manual mills.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for finish milling, slotting, and profiling operations in ferrous and non-ferrous materials. The uncoated micrograin carbide substrate performs well in aluminum, brass, and mild steels where coating adhesion or heat buildup is a concern. The 3\/8 inch shank diameter fits standard ER collets, end mill holders, and set-screw-style tool holders used on vertical machining centers, CNC routers, and manual knee mills. Machinists and toolroom operators working in job shop and production environments will find the 6-flute design effective for high-speed finishing passes with light radial engagement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for extended tool life and edge stability\u003c\/li\u003e\n  \u003cli\u003e6-flute spiral geometry with 45-degree helix angle for improved chip flow and surface finish\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge milling without a pre-drilled entry hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute configuration for standard spindle operation\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for non-ferrous materials and applications where coating is not preferred\u003c\/li\u003e\n  \u003cli\u003eMill diameter tolerance of +0.000 \/ -0.002 inches for consistent fitment and dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard tooling option for 3\/8 inch ER collet chucks, end mill holders, and set-screw holders on CNC machining centers and manual milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Power down and lock out the spindle before loading or unloading the tool. Ensure the shank is fully seated and properly torqued in the tool holder per the holder manufacturer specifications. Verify runout at the tool tip with a dial indicator before beginning cuts to protect both the tool and the workpiece.\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: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch (1.0000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 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: +0.000 \/ -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: 0.144 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: 12177411\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732012204338,"sku":"12177411","price":65.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b2b40f806cf4f60879107d59958989ab.jpg?v=1788738079","url":"https:\/\/voomisupply.com\/products\/accupro-12177411-square-end-mill-3-8-inch-6-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
