Hertel E599924390 Ball End Mill 0.125 in 2 Flute Carbide

Product Description

The HERTEL E599924390 is a solid carbide ball end mill designed for precision milling operations in metalworking and machining applications. With a 0.125-inch diameter and a 0.375-inch length of cut, this double-end tool delivers two usable cutting ends, extending service life and reducing per-cut tooling cost. The 2-flute geometry supports efficient chip evacuation in a range of materials. Right-hand cutting and right-hand flute direction are standard. At 2.0 inches overall length with a 0.125-inch shank diameter, this end mill fits standard collets and tool holders used in CNC and manual milling setups.

This end mill is suited for finish milling, contouring, and profiling operations where a ball-nose radius is required. It is commonly used in tool-and-die, mold making, aerospace component machining, and general precision part production. The solid carbide construction handles hardened steels, stainless alloys, cast iron, and non-ferrous materials at higher speeds than high-speed steel alternatives. It is intended for use by machinists and CNC operators working on vertical or horizontal machining centers and manual knee mills.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cuts
• Ball nose geometry for contouring, profiling, and 3D surface work
• Double-end design provides two cutting ends per tool
• 2-flute configuration promotes chip clearance in slotting and ramping passes
• Right-hand cut and right-hand helix for standard spindle compatibility
• 0.125-inch shank fits commonly available collets and shrink-fit holders

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide ball end mill for standard 0.125-inch collet and tool holder systems on CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and the control is in an e-stop or locked-out state before changing tooling. Confirm the shank is fully seated in the collet or holder to the recommended gauge-line depth and torque the retention nut per the tool holder manufacturer's specifications. Inspect the cutting edges for chips or wear before each use and replace when surface finish or dimensional accuracy degrades.
