Osg 464-5000-BN Ball End Mill 0.5 in 4 Flute Solid Carbide

Product Description

The OSG 464-5000-BN is a solid carbide ball end mill designed for precision milling across a wide range of ferrous and non-ferrous materials. Built to Series 464BN specifications, this single-end tool features a 0.5-inch diameter, a 4-flute helical configuration, and a 2-inch length of cut, making it well-suited for both roughing and finishing operations. The micrograin carbide construction provides rigidity and wear resistance at elevated cutting speeds. A 30-degree medium helix angle balances chip evacuation with cutting stability. This tool is installed by machinists and CNC operators working in job shops, aerospace, and general metalworking environments.

This end mill is used in vertical and horizontal milling centers for profiling, contouring, and slot milling in materials including steel, stainless steel, cast iron, non-ferrous metals, and hard materials. The long-series body with a 4-inch overall length allows reach into deeper features without sacrificing rigidity. The bright uncoated finish suits applications where coating interaction with the workpiece or coolant chemistry is a concern. The straight cylindrical shank is compatible with standard ER collets and end mill holders.

Key Features

• Solid micrograin carbide construction for rigidity and extended tool life
• 4-flute helical design supports both roughing and finishing in a single tool
• 0.25-inch nose radius delivers consistent ball-end profile for 3D contour work
• 30-degree medium helix angle promotes effective chip evacuation
• Long-series length type with 2-inch reach length for deeper feature access
• Bright uncoated finish suitable for non-ferrous and hard material applications

Compatibility

Compatible with steel, stainless steel, cast iron, non-ferrous metals, and hard materials as noted in OSG Series 464BN specifications. Fits standard straight-bore end mill holders and ER collet chucks accepting a 0.5-inch straight cylindrical shank.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Secure the shank fully in the tool holder to the recommended gauge line and verify runout before cutting. Power down and lock out the spindle before changing or inspecting tooling. Do not exceed the tool manufacturer's recommended depth-of-cut or feed-per-tooth values for the workpiece material grade being machined.
