Hertel E599924412 Ball End Mill 0.125 in 4 Flute Carbide

Product Description

The HERTEL E599924412 is a solid carbide ball end mill designed for precision milling operations in metalworking and machining applications. The tool features a 0.125 inch cutting diameter with a 0.375 inch length of cut and a 30-degree helix angle, making it well-suited for profiling, slotting, and contouring in ferrous and non-ferrous materials. With four flutes and a right-hand cutting direction, it delivers efficient chip evacuation and smooth surface finishes. The double-end configuration provides two usable cutting ends, extending tool life per unit. Overall length is 3 inches with a 3/8 inch shank diameter. The uncoated carbide construction is suitable for dry or coolant-assisted cutting environments.

This ball end mill is used in CNC machining centers, manual knee mills, and tool room equipment for finish profiling, 3D contouring, and small-radius corner work. The 0.125 inch diameter makes it appropriate for fine-detail work on dies, molds, and precision components. It is installed by machinists and tooling technicians in job shops, production facilities, and maintenance departments. The double-end design is common in tool crib environments where maximizing usable cutting edges per tool is a priority.

Key Features

• 0.125 inch ball end cutting diameter for fine-detail milling and 3D contouring
• 4-flute configuration with right-hand spiral flutes for efficient chip evacuation
• 30-degree helix angle balances cutting force and surface finish quality
• Double-end design provides two usable cutting ends per tool
• Solid carbide construction for rigidity and wear resistance
• Uncoated finish suitable for a range of cutting conditions with or without coolant

Compatibility

Designed as a standard tooling replacement for CNC machining centers and manual mills accepting a 3/8 inch straight shank end mill holder or collet.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. The spindle must be fully stopped and the machine placed in an off or e-stop state before changing tooling. Use a properly sized collet or end mill holder rated for the 3/8 inch shank diameter and torque the retention mechanism per the holder manufacturer specification. Inspect the shank and cutting end for chips or runout before beginning a cut.
