Hertel E699924523 Ball End Mill 0.2344 in 4 Flute Carbide

Product Description

The HERTEL E699924523 is a single-end ball end mill designed for precision milling operations in ferrous and non-ferrous materials. Built from solid carbide, it delivers the rigidity and wear resistance required for demanding cutting applications. The tool measures 0.2344 inches in diameter with a 0.75-inch length of cut and a 2.5-inch overall length. A TiN (titanium nitride) coating reduces friction and extends tool life in production environments. This end mill is installed and used by machinists and tool-and-die professionals working on CNC machining centers and manual mills.

This ball end mill is suited for contour milling, profiling, and 3D surface finishing where a radiused cutting edge is required. The 4-flute design provides a good balance of chip clearance and surface finish quality. With a 0.25-inch shank diameter, it fits standard collets and end mill holders common in both vertical machining centers and manual knee mills. It is typically applied in mold making, die work, and general precision part machining at the small-diameter range.

Key Features

• Solid carbide construction for rigidity and extended tool life
• TiN coating reduces friction and improves wear resistance
• 4-flute geometry balances chip evacuation and surface finish
• Ball end profile suited for contour, profile, and 3D surface milling
• Right-hand cutting and right-hand flute direction for standard CNC and manual mill setups
• Single-end design with 0.25-inch shank for common collet compatibility

Compatibility

Designed as an OEM-style solid carbide ball end mill fitting standard 0.25-inch collets and end mill holders on CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by machinists using a collet chuck or end mill holder rated for the 0.25-inch shank diameter. Ensure the spindle is fully stopped and the machine is in a safe lockout state before changing tooling. Verify runout with a dial indicator after seating the tool, as excessive runout accelerates wear on small-diameter carbide end mills. Follow the machine tool manufacturer guidelines for speeds and feeds appropriate to the workpiece material and coating type.
