It features a 3.00 mm diameter, a 10.00 mm length of cut, and a 3-flute solid carbide construction. The 30-degree medium helix angle promotes efficient chip evacuation while maintaining surface finish quality. The bright uncoated finish makes it suitable for a range of workpiece materials. This tool is typically installed and operated by machinists and CNC programmers working in precision manufacturing environments.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling operations on steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. The 3.00 mm shank diameter matches the cutting diameter, allowing straightforward setup in standard collet chucks or end mill holders. With a 39.00 mm overall length and a 1.50 mm nose radius, it is appropriate for profiling, contouring, and slotting operations where a ball-nose geometry is required. The straight-cylindrical shank ensures consistent clamping in standard toolholding systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3.00 mm cutting diameter with a 1.50 mm nose radius for ball-nose profiling and contouring\u003c\/li\u003e\n\u003cli\u003e3-flute solid carbide construction supports both roughing and finishing cuts\u003c\/li\u003e\n\u003cli\u003e30-degree medium helix angle promotes efficient chip flow\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank for secure seating in standard collet and end mill holders\u003c\/li\u003e\n\u003cli\u003eSingle-end design from the OSG 403BN standard carbide end mill series\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for machining centers and CNC milling machines requiring a 3.00 mm ball end mill with a straight-cylindrical shank. Compatible workpiece material categories include steel (P), stainless steel (M), cast iron (K), non-ferrous metal (N), superalloys and titanium (S), and hard materials (H) per ISO material classification codes provided in the product data.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis end mill should be installed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify collet or end mill holder bore size matches the 3.00 mm shank diameter before clamping. Do not exceed the tool manufacturer's recommended cutting parameters for the selected workpiece material and machine type.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3.00 mm (0.1181 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 10.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 39.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 1.50 mm\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\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 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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.00\/-0.05 mm\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: Metric\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: 403-1181-BN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51731717226802,"sku":"403-1181-BN","price":25.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8349d5a16618b087d293b57f9ada9122.jpg?v=1788734218","url":"https:\/\/voomisupply.com\/products\/osg-403-1181-bn-ball-end-mill-3mm-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
