It features a 1\/16 inch (0.0625 inch) mill diameter with a TiAlN PVD coating that extends tool life under elevated cutting temperatures. The three-flute, right-hand spiral configuration supports both roughing and finishing operations. With a 30-degree medium helix angle and a nose radius of 0.0313 inches, this tool delivers clean ball-profile cuts at miniature scales where rigidity and tolerance consistency are critical.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for CNC machining centers and milling applications where small-diameter, tight-tolerance work is required. The 403BN series is positioned as an economical solid carbide option built to OSG quality standards, making it appropriate for production shops managing tooling budgets without sacrificing dimensional consistency. Its straight-cylindrical shank accepts standard collet and end mill holders sized for a 1\/8 inch shank. Typical applications include die and mold work, aerospace component machining, and precision part production involving hard or exotic workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiAlN PVD coating for heat resistance and extended tool life in ferrous and hard materials\u003c\/li\u003e\n\u003cli\u003e3-flute right-hand spiral design supports roughing and finishing in a single tool\u003c\/li\u003e\n\u003cli\u003e30-degree medium helix angle for balanced chip evacuation and cutting force\u003c\/li\u003e\n\u003cli\u003e0.0313 inch nose radius for accurate ball-profile geometry at 1\/16 inch diameter\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and minimal deflection at miniature diameters\u003c\/li\u003e\n\u003cli\u003eMill diameter tolerance of +0.0000 \/ -0.0020 inches for consistent dimensional output\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials (ISO material codes P, M, K, N, S, H).

Secure the straight-cylindrical shank in a properly sized collet or end mill holder, ensuring runout is minimized before cutting, as deflection is amplified at 1\/16 inch diameters. Verify spindle speed and feed rate parameters against the material being cut before engaging the workpiece. Handle solid carbide tooling carefully to avoid chipping the cutting edges during setup and storage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/16 inch (0.0625 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-1\/2 inches (1.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 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\u003eNose Radius\u003c\/strong\u003e: 0.0313 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: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\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\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Classification\u003c\/strong\u003e: PVD\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\u003eVariable Helix\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: 0.1 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: 403-0625-BN11\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51755316347186,"sku":"403-0625-BN11","price":29.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e95fdd6fbcf11bfedef627e9205cb27f_2c21ea38-b381-42e4-bac9-651a532c0c24.jpg?v=1788953510","url":"https:\/\/voomisupply.com\/products\/osg-403-0625-bn11-ball-end-mill-1-16-in-3-flute-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
