Hertel E5250040 Ball End Mill 0.625 in 4 Flute Carbide

Product Description

The HERTEL E5250040 is a solid carbide ball end mill designed for precision milling operations in metal, composites, and hard materials. With a 0.625 inch cutting diameter, a 1.25 inch length of cut, and a 4-flute configuration, this end mill delivers smooth finishes and efficient chip evacuation in both roughing and finishing passes. The 30-degree helix angle promotes clean cutting action and reduces chatter. At 3.5 inches overall length with a 0.625 inch shank, it fits standard milling collets and tool holders. The bright uncoated finish suits applications where coating interaction with the workpiece material is a concern.

This end mill is suited for CNC machining centers and manual knee mills in job shops, tool rooms, and production environments. It handles contour milling, profiling, and 3D surface work where a ball-nose geometry is required. The single-end design with right-hand cutting and right-hand flute direction makes it a standard fit for conventional vertical and horizontal milling setups. Machinists and tooling specialists select this geometry for slotting, pocketing, and blending operations on ferrous and non-ferrous workpieces.

Key Features

• 0.625 inch ball-nose cutting diameter for contour and 3D surface milling
• 4-flute solid carbide construction for rigidity and wear resistance
• 1.25 inch length of cut accommodates moderate-depth profiling passes
• 30-degree helix angle reduces cutting forces and minimizes chatter
• Bright uncoated finish suitable for a wide range of workpiece materials
• Right-hand cut and right-hand flute direction for standard milling spindles

Compatibility

Designed as a standard-geometry solid carbide ball end mill compatible with 0.625 inch collets, shrink-fit holders, and milling chucks used on CNC and manual milling machines.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the spindle before changing tooling. Ensure the shank is fully seated and the tool holder is torqued to the machine manufacturer specification before running. Inspect the cutting edges for chips or wear before each use and do not exceed the recommended depth of cut for the material being machined.
