Osg 414-5000-BN11 Ball End Mill 1/2 in 4 Flute Solid Carbide

Product Description

The OSG 414-5000-BN11 is a solid carbide ball end mill designed for precision milling operations in ferrous and hardened materials. Part of the OSG 414BN series, it features a 1/2-inch cutting diameter, a 5/8-inch length of cut, and a 2-1/2-inch overall length. The 4-flute, right-hand spiral configuration paired with a 30-degree helix angle promotes efficient chip evacuation and smooth surface finishes. A TiAlN coating adds heat resistance and extends tool life in demanding cutting environments. Manufactured from micrograin solid carbide, this single-end stub-length tool delivers rigidity and accuracy in tight-tolerance applications.

This ball end mill is suited for CNC machining centers and manual mills used in metalworking, tooling, and die-and-mold applications. The stub-length design reduces deflection in moderate-depth profiling, contouring, and finishing passes. The 1/2-inch shank diameter fits standard ER collet chucks, end mill holders, and shrink-fit toolholders commonly used in production and job-shop environments. The right-hand cutting direction makes it compatible with conventional spindle rotation on vertical and horizontal machining centers.

Key Features

• Solid micrograin carbide substrate for improved wear resistance and edge retention
• TiAlN coating for elevated heat resistance in high-speed and dry cutting applications
• 4-flute, right-hand spiral design with 30-degree helix angle for efficient chip evacuation
• Stub-length geometry minimizes deflection in profiling and contouring operations
• Single-end construction with 1/2-inch shank for compatibility with standard toolholders
• Ball nose profile for 3D contouring, ramp milling, and radius floor finishing

Compatibility

Designed as an OEM-style cutting tool for use in standard 1/2-inch diameter end mill holders, ER collet chucks, and shrink-fit tooling systems on CNC and manual milling platforms.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before loading or unloading the tool. Seat the shank fully in the toolholder and torque the retention mechanism according to the toolholder manufacturer specifications. Verify runout with a dial indicator before initiating a cut to protect both the tool and the workpiece.
