Built from micrograin carbide and coated with AlTiN for heat and wear resistance, this tool handles hard materials and elevated cutting speeds with consistency. It features a 3\/16 inch cutting diameter, a 5\/16 inch length of cut, and a 6-flute geometry with a 45-degree helix angle for efficient chip evacuation and smooth surface finishes. Single-end configuration and right-hand cutting direction make it a straightforward replacement for standard finishing and semi-finishing operations on CNC machining centers and manual mills.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for ferrous and non-ferrous machining in both production and job-shop settings. The 6-flute design supports higher feed rates compared to 4-flute tools, making it a practical choice when cycle time and surface finish both matter. The AlTiN coating extends tool life in harder steels, stainless, and cast iron. The 3\/16 inch shank diameter matches the cutting diameter, allowing direct collet chuck mounting without adapters in standard toolholding systems. Overall length is 2 inches, keeping the tool compact and rigid for shallow-to-medium depth applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for thermal resistance and extended tool life in hard materials\u003c\/li\u003e\n\u003cli\u003e6-flute spiral geometry with 45-degree helix angle for efficient chip flow\u003c\/li\u003e\n\u003cli\u003eCentercutting capable, allowing plunge entry into workpieces\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle compatibility\u003c\/li\u003e\n\u003cli\u003eTight mill diameter tolerance of +0.000\/-0.002 inches for precise fit and finish\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard-spec square end mill for CNC machining centers and manual milling machines using 3\/16 inch collet or end mill holders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is in an e-stop or locked-out state before changing tooling. Seat the shank fully into the collet or holder before torquing the retention nut to the toolholder specification. Inspect the shank and collet bore for chips or debris before mounting to avoid runout issues.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\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\u003eNumber of Flutes\u003c\/strong\u003e: 6\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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\u003eConfiguration\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.029 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: 12177404\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51749354537266,"sku":"12177404","price":45.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1f17ed1ccc86b3ff00ecf5a320e08b4a.jpg?v=1788904893","url":"https:\/\/voomisupply.com\/products\/accupro-12177404-square-end-mill-3-16-in-6-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
