It features a 0.75-inch diameter cutting head, a 1.5-inch length of cut, and a 4-inch overall length with a matching 0.75-inch straight-cylindrical shank. The 2-flute, right-hand helical design runs at a 30-degree helix angle and is manufactured from micrograin carbide in a bright, uncoated finish. This single-end mill is built to OSG dimensional standards with tight tolerances, making it suitable for both roughing and finishing operations.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for use in machining centers and manual mills across a broad range of workpiece materials, including steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. The ball nose geometry makes it well-suited for contour milling, 3D profiling, and radius-floor pocket work. It fits standard toolholders accepting a 0.75-inch shank. The Series 402BN lineup is positioned as an economical solid carbide option that maintains consistent tolerancing across production runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.75-inch ball nose diameter with 0.375-inch nose radius for contour and 3D profile cuts\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide construction for wear resistance and dimensional stability\u003c\/li\u003e\n  \u003cli\u003e2-flute, right-hand helical design at 30-degree helix angle for chip evacuation\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for non-ferrous and general-purpose steel milling\u003c\/li\u003e\n  \u003cli\u003eMill diameter tolerance of +0.0000 \/ -0.0020 inches for consistent fitment and repeatability\u003c\/li\u003e\n  \u003cli\u003eRated for roughing and finishing across P, M, K, N, S, and H workpiece material categories\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials as designated by material codes P, M, K, N, S, and H.

Ensure the toolholder bore and shank are clean and free of chips or debris before seating the end mill. Confirm runout with a dial indicator before beginning a cut to protect both the tool and the workpiece. Follow the machine manufacturer and tooling guidelines for recommended speeds, feeds, and depth-of-cut for the specific workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.375 inches\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: Helical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 \/ -0.0020 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.0000 \/ -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 402BN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.78 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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 402-7500-BN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51731296813362,"sku":"402-7500-BN","price":203.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e8993318ff0bcdcbb8526c6b694aab00_8e8b7260-783b-4239-8d58-f7c8edff0ef3.jpg?v=1788729411","url":"https:\/\/voomisupply.com\/products\/osg-402-7500-bn-ball-end-mill-0-75in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
