Built from micrograin solid carbide and coated with TiCN, this tool delivers edge hardness and wear resistance well above standard HSS tooling. The 0.3125-inch (5\/16 inch) cutting diameter pairs with a 1.125-inch length of cut, giving machinists reach for moderate-depth passes without sacrificing rigidity. The 40-degree helix angle promotes smooth chip evacuation and reduces chatter. Licensed machinists and CNC operators install this tool for finish and semi-finish cuts in ferrous and non-ferrous materials.\u003c\/p\u003e\n\u003cp\u003eThis ball end mill suits production and job-shop environments where close-tolerance contouring is required. The 5\/16-inch shank diameter fits standard collets and end mill holders on vertical machining centers, CNC routers, and manual knee mills. The long-length configuration with a 3-inch overall length provides clearance for deeper cavity work or stepped-feature access. Right-hand cut and right-hand spiral flute geometry make it compatible with conventional CNC spindle rotation. It is sold as a single-end tool, meaning only one cutting end is present.\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\u003eTiCN coating increases surface hardness and reduces friction at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes efficient chip evacuation and reduces vibration\u003c\/li\u003e\n  \u003cli\u003e2-flute design provides clearance for chip flow in slotting and profiling cuts\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with right-hand spiral flute geometry for standard CNC spindle use\u003c\/li\u003e\n  \u003cli\u003eLong-length body (3 inches OAL) allows access to deeper features and cavities\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style cutting tool for use in standard 5\/16-inch collets and end mill holders on CNC machining centers and manual mills with right-hand spindle rotation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Secure the shank fully into a clean, undamaged collet or end mill holder and torque the retention mechanism to the machine manufacturer's specification. Inspect the cutting edges for chips or coating damage before use. Never exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and coating type.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.3125 inches (5\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.125 inches (1-1\/8 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: 0.3125 inches (5\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 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: TiCN\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\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: 12184221\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51747071951154,"sku":"12184221","price":77.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7df1fcaaca86c1fe97ae934a4e6d75a2.jpg?v=1788875746","url":"https:\/\/voomisupply.com\/products\/accupro-12184221-ball-end-mill-5-16-in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
