Hertel E599924389 Ball End Mill 0.125 in 2 Flute Carbide

Product Description

The HERTEL E599924389 is a solid carbide ball end mill designed for precision milling operations in metal, composite, and hard-material applications. With a 0.125-inch milling diameter and a 0.375-inch length of cut, this tool removes material in tight-radius contours, slots, and 3D profile work where a flat end mill cannot reach. The double-end configuration provides two usable cutting ends, extending tool life before a replacement is needed. A 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces. Right-hand cutting and right-hand flute direction are standard for conventional CNC and manual milling setups. The uncoated solid carbide construction delivers consistent edge integrity across a range of workpiece materials.

This end mill is suited for precision machining work in job shops, tool-and-die operations, and production CNC environments. The 0.125-inch diameter makes it appropriate for fine-detail work such as engraving, contouring, and small-pocket milling. The 3/8-inch shank diameter fits standard collet systems commonly found on vertical machining centers and CNC routers. With a 3-inch overall length, the tool provides adequate reach for most shallow-to-medium-depth applications without excessive overhang.

Key Features

• Double-end design provides two cutting ends per tool, maximizing value per unit
• 0.125-inch ball nose diameter for tight-radius contouring and fine-detail profiling
• 30-degree helix angle for efficient chip evacuation and reduced cutting pressure
• Solid carbide construction for rigidity and edge retention in hard materials
• Uncoated finish suitable for use across a broad range of base materials
• Right-hand cut and right-hand flute direction for standard spindle compatibility

Compatibility

Designed as a standard replacement or production-stock ball end mill for CNC machining centers and manual mills accepting a 3/8-inch collet or end mill holder.

Installation Notes

This tool should be installed by a qualified machinist following the machine manufacturer guidelines for tool holding and runout tolerances. Confirm collet size matches the 3/8-inch shank before securing. Power down and lock out the spindle before changing tooling. Avoid exceeding the recommended depth of cut for the diameter to prevent tool deflection or breakage.
