Part of the OSG 403BN series, it features a 3\/8 inch cutting diameter with a matching 3\/8 inch straight-cylindrical shank, three spiral flutes, and a 30-degree medium helix angle. The bright uncoated finish suits a wide range of workpiece materials. At 2.5 inches overall length with a 1 inch length of cut, this is a single-end, standard-length tool intended for use by machinists and CNC operators in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis ball end mill is suited for milling operations across a broad spectrum of materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. The 3\/8 inch ball nose profile makes it appropriate for contour milling, profiling, slotting, and finishing passes on complex 3D surfaces. Right-hand cut and right-hand flute direction are standard for conventional CNC milling setups. No extended reach, no coolant-through capability, and no chipbreaker — straightforward geometry for general-purpose work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance across multiple workpiece materials\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch ball nose diameter with a 0.1875 inch nose radius for accurate profiling and contouring\u003c\/li\u003e\n  \u003cli\u003eThree spiral flutes with a 30-degree medium helix angle for balanced chip evacuation\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration; right-hand cut and right-hand flute direction\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish compatible with steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials\u003c\/li\u003e\n  \u003cli\u003eMill diameter tolerance of +0.0000 \/ -0.0020 inches for consistent part-to-part accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eSuitable for use on CNC machining centers and manual mills accepting a 3\/8 inch straight-cylindrical shank.

Secure the shank in a collet or end mill holder rated for the 3\/8 inch shank diameter, ensuring proper seating depth before tightening. Confirm spindle and tool holding are free of runout before beginning a cut. Follow machine tool manufacturer guidelines for speeds, feeds, and depth of cut appropriate to the workpiece material and operation type.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\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\u003eHelix Style\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\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\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\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: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 403BN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: 403-3750-BN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51727748727090,"sku":"403-3750-BN","price":58.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6ca4d89aff0105d63d4e5dd7b3edcf15.jpg?v=1788681659","url":"https:\/\/voomisupply.com\/products\/osg-403-3750-bn-ball-end-mill-3-8-in-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
