It features a 1 inch cutting diameter, a 1.5 inch length of cut, and a 4-inch overall length with a straight cylindrical 1 inch shank. The four-flute helical design with a 30-degree helix angle supports both roughing and finishing operations in a single tool. Micrograin carbide construction provides the edge retention and rigidity needed for demanding cuts in steel, stainless steel, cast iron, and harder materials. This is a single-end tool with a bright uncoated finish, suited for applications where coating is not required or where coolant-based lubrication is preferred.\u003c\/p\u003e\u003cp\u003eThis end mill is part of the OSG 404BN series, which targets production shops and toolrooms looking for consistent tolerancing at a practical price point. It is suited for use on CNC machining centers and manual mills where ball-end profiling, contouring, slotting, and 3D surface work are performed. Compatible workpiece materials include steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. The right-hand cut and right-hand flute direction make it compatible with standard spindle configurations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1 inch ball nose diameter with a 0.5 inch nose radius for accurate profiling and contouring\u003c\/li\u003e\n\u003cli\u003eFour helical flutes with a 30-degree medium helix angle for balanced chip evacuation during roughing and finishing\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for edge retention in ferrous and hard workpiece materials\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for non-ferrous materials and coolant-assisted cutting environments\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank for use in standard end mill holders and collet chucks\u003c\/li\u003e\n\u003cli\u003eSingle-end design rated for steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard CNC machining centers and manual mills with right-hand spindle rotation.

Secure the shank fully in a properly sized end mill holder or collet chuck, ensuring adequate engagement depth and runout within acceptable limits. Confirm spindle rotation direction matches the right-hand cutting geometry before starting the spindle. No coolant-through capability is present on this tool, so external coolant or mist lubrication should be applied as appropriate for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 4\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin Grade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eSeries\u003c\/strong\u003e: 404BN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.39 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 404-1000-BN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51731518488882,"sku":"404-1000-BN","price":370.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/03ac6feff1890f7c79e3423dc2717682_5af525f2-e209-4177-bb3c-8e0e2ec76150.jpg?v=1788732047","url":"https:\/\/voomisupply.com\/products\/osg-404-1000-bn-ball-end-mill-1-inch-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
