It measures 0.3125 inches in diameter with a 0.5625-inch length of cut and an overall length of 3.5 inches. Manufactured from high speed steel and finished with a titanium nitride (TiN) coating, it delivers improved wear resistance and extended tool life compared to uncoated HSS tooling. The two-flute geometry and 30-degree helix angle promote efficient chip evacuation during milling operations. This end mill belongs to the HD-2B series and is suited for general-purpose milling in machine shops and production environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is appropriate for use in vertical machining centers, knee mills, and CNC milling machines where ball-nose profiling or finishing passes on curved or ramped surfaces are required. The double-end configuration doubles usable cutting life from a single tool. The 0.375-inch shank diameter fits standard ER and R8 collets common in shop environments. It is typically installed and operated by machinists and tool-and-die professionals working in job shop, manufacturing, and maintenance machining applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble-end design provides two usable cutting ends per tool\u003c\/li\u003e\n  \u003cli\u003eTiN coating increases surface hardness and reduces friction for longer tool life\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes smooth chip flow and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eTwo-flute geometry supports slotting and profiling in a variety of materials\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction offers toughness and regrindability\u003c\/li\u003e\n  \u003cli\u003eHD-2B series designation indicates heavy-duty, general-purpose ball end mill classification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use ball end mill for standard 0.375-inch collet or chuck setups on vertical and CNC milling machines requiring a 5\/16-inch ball-nose end mill.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist. Ensure the machine spindle is fully powered down and the drawbar or collet nut is secure before beginning tool changes. Use the correct collet size for the 0.375-inch shank to prevent runout and slippage during cutting. Verify tool overhang is minimized to reduce deflection, and confirm proper cutting parameters for high speed steel tooling before initiating a cut.\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: 0.5625 inches (9\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 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: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Double End\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\u003eSeries\u003c\/strong\u003e: HD-2B\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: CLEVELAND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C39148\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51717286396210,"sku":"C39148","price":116.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bdcff29f49afcce8f16dd67719344641.jpg?v=1788537830","url":"https:\/\/voomisupply.com\/products\/cleveland-c39148-ball-end-mill-5-16-in-2-flute-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
