Hertel E599924522 Ball End Mill 4 Flute Solid Carbide

Product Description

The HERTEL E599924522 is a solid carbide ball end mill designed for precision milling operations in metal fabrication and machining environments. With a 0.2188-inch cutting diameter and a 0.5-inch length of cut, this tool handles contoured surfaces, slotting, and profiling work in tight geometries. The 4-flute configuration improves chip evacuation and finish quality compared to 2-flute alternatives. A 30-degree helix angle balances cutting efficiency with lateral load management. At 2.0 inches overall length with a 0.25-inch shank diameter, this end mill fits standard toolholders and collet chucks commonly used in CNC mills and manual knee mills. Uncoated carbide construction suits general-purpose ferrous and non-ferrous applications.

This end mill is suited for light to medium-duty milling operations on steel, aluminum, and similar materials. The single-end, right-hand cutting geometry with right-hand flute direction makes it a standard choice for CNC machining centers and manual milling setups where ball-nose profiling is required. The 0.2188-inch diameter is appropriate for finishing passes on small contours, die work, mold cavities, and similar detail machining tasks. Machinists and tool-and-die professionals working on precision components will find this a practical fit for 3-axis and multi-axis profiling paths.

Compatibility

Designed as an OEM-style solid carbide ball end mill for use in standard 1/4-inch collet chucks and toolholders on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank a minimum of 2.5 times the shank diameter into the collet or toolholder to minimize runout and tool pullout risk. Verify collet size matches the 0.25-inch shank diameter before tightening.
