It features a 1-inch cutting diameter, a 1.5-inch length of cut, and a 30-degree helix angle that balances chip evacuation with cutting stability. The micrograin carbide substrate provides edge rigidity and wear resistance without a coating, offering a bright, uncoated finish suitable for applications where coating interaction or cost is a concern. Three flutes in a helical, right-hand configuration deliver consistent chip flow in standard milling setups. This end mill is installed and operated by machinists and tooling professionals in CNC machining environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. It is appropriate for both roughing passes and finish milling where a ball nose profile is required for contoured or radius-floor features. The single-end design and straight-cylindrical shank with a 1-inch diameter allow direct mounting in standard ER or end mill holders without additional adapters. This tool fits general-purpose CNC milling applications in job shops, tool rooms, and production environments where a reliable, uncoated carbide ball mill is needed at a standard reach.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-inch ball nose cutting diameter with a 0.5-inch nose radius for accurate radius profiling\u003c\/li\u003e\n  \u003cli\u003e3-flute helical geometry in right-hand cut and right-hand flute direction\u003c\/li\u003e\n  \u003cli\u003e30-degree medium helix angle for balanced cutting performance in roughing and finishing\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide construction for edge retention across difficult workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish compatible with a broad range of workpiece material types\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank at 1-inch diameter for direct holder mounting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible workpiece materials include steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials.

The machine spindle must be fully stopped and locked out before mounting or removing the tool. Ensure the holder bore and shank are clean and free of chips or debris before clamping to full engagement depth. Follow the machine tool manufacturer torque specifications for the holder style in use and verify runout after installation 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: 1 inch\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: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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: 0.5 inches\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\u003eCutting 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: Bright\/Uncoated\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\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 403BN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.4 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.5 inches L x 1.25 inches W x 1.25 inches H\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: 403-1000-BN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51729057939762,"sku":"403-1000-BN","price":370.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7a930fda024323941a34a66fcd2a63b9.jpg?v=1788699372","url":"https:\/\/voomisupply.com\/products\/osg-403-1000-bn-ball-end-mill-1-in-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
