Osg 404-1406-BN Ball End Mill 0.1406 in 4 Flute Carbide

Product Description

The OSG 404-1406-BN is a solid carbide ball end mill designed for precision milling operations in ferrous and non-ferrous materials. It features a 0.1406-inch cutting diameter, a 0.5-inch length of cut, and a 4-flute helical configuration with a 30-degree helix angle. The micrograin carbide construction provides rigidity and edge retention suited for both roughing and finishing passes. The bright uncoated finish makes it suitable for a range of secondary workpiece materials where coating interaction is a concern. Machinists and tool-and-die shops working with small-diameter milling operations will find this a reliable, consistent performer within the OSG 404BN series.

This end mill is built for general-purpose milling across a broad range of materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. It fits standard small-diameter toolholding setups with a 3/16-inch straight cylindrical shank. The single-end, right-hand cutting and flute direction make it compatible with conventional vertical and horizontal CNC machining centers as well as manual milling machines running right-hand spindle rotation.

Key Features

• Solid micrograin carbide construction for consistent tolerancing and edge durability
• 4-flute helical design with 30-degree medium helix for balanced cutting performance in roughing and finishing
• 0.0703-inch nose radius provides true ball-end geometry for contoured and 3D milling paths
• Bright uncoated finish suitable for non-ferrous metals and applications where coated tooling is not preferred
• Right-hand cut and right-hand flute direction for standard CNC spindle compatibility
• Part of the OSG 404BN series, manufactured to consistent dimensional tolerances with a mill diameter tolerance of +0.0000 / -0.0020 inches

Compatibility

Rated for use on steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. Designed for use in standard small-diameter CNC or manual milling applications requiring a 3/16-inch straight cylindrical shank.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill from the toolholder. Use a properly sized collet or end mill holder that matches the 3/16-inch shank diameter to prevent runout and tool pull-out. Verify workpiece material compatibility and select appropriate feed and speed parameters before beginning the cut.
