Osg 404-1968-BN Ball End Mill 5 Mm 4 Flute Solid Carbide

Product Description

The OSG 404-1968-BN is a solid carbide ball end mill designed for precise milling operations across a wide range of workpiece materials. Built to OSG Series 404BN standards, this single-end tool features a 5.00 mm cutting diameter, a 16.00 mm length of cut, and a 4-flute spiral geometry with a 30-degree helix angle. The micrograin carbide construction provides the rigidity and edge retention needed for both roughing and finishing passes. At 51.00 mm overall length with a 5.00 mm straight-cylindrical shank, it fits standard collet and end mill holders used in CNC machining centers and manual mills.

This end mill is suited for machining steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. The ball nose profile makes it appropriate for 3D contouring, profiling, slotting, and finishing of complex surfaces. Right-hand cutting and right-hand flute direction are standard for conventional CNC spindle setups. The bright uncoated finish is compatible with dry cutting or coolant-assisted operations, though this tool does not include through-coolant capability.

Key Features

• 5.00 mm cutting diameter with 2.50 mm nose radius for accurate ball-end profiling
• 4-flute spiral geometry with 30-degree medium helix angle for balanced chip evacuation
• Micrograin solid carbide construction for consistent tolerancing and edge life
• Mill diameter tolerance of +0.00 / -0.05 mm for repeatable fitment
• Single-end, right-hand cut design for standard CNC and manual mill setups
• Rated for roughing and finishing across steel, stainless, cast iron, non-ferrous, superalloys, titanium, and hard materials

Compatibility

Compatible with workpiece materials coded P (steel), M (stainless steel), K (cast iron), N (non-ferrous metal), S (superalloys and titanium), and H (hard material) per ISO material classification. Fits standard 5.00 mm collet and end mill tool holders.

Installation Notes

Installation is performed by machinists and CNC operators using a properly sized collet or end mill holder. Ensure the spindle is fully stopped and the machine is in a safe state before loading or unloading the tool. Confirm runout at the collet before cutting to stay within the stated diameter tolerance. Follow the machine tool manufacturer and cutting tool guidelines for feed rate, depth of cut, and spindle speed when applying this end mill to hard or difficult-to-machine materials.
