Hertel E599924420 Ball End Mill 0.25in 4 Flute Carbide

Product Description

The HERTEL E599924420 is a solid carbide ball end mill designed for precision milling operations in ferrous and non-ferrous materials. Built with a 0.25-inch mill diameter and four flutes, it delivers smooth chip evacuation and consistent surface finish in profiling, contouring, and slotting applications. The ball-nose geometry generates a spherical cutting profile suited to 3D contour work and curved surface finishing. With a 30-degree helix angle and right-hand cutting direction, the tool maintains stable engagement under load. Licensed machinists and CNC operators install this tool in standard milling machines, machining centers, and CNC routers.

This end mill suits production and job-shop environments where tight tolerances and surface quality are required. The double-end configuration provides two usable cutting ends, extending tool life per unit. The 0.625-inch length of cut and 3.5-inch overall length position this tool for moderate-depth cavities and general-purpose profiling. The 0.375-inch shank diameter fits standard collet and end mill holder systems common in vertical machining centers.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cuts
• Ball-nose geometry for 3D contouring and curved surface profiling
• Double-end design delivers two cutting ends per tool
• 30-degree helix angle promotes smooth cutting action and chip flow
• Right-hand cutting and right-hand flute direction for standard milling setups
• Bright/uncoated finish suitable for use with cutting fluids across a range of materials

Compatibility

Designed as a direct-fit replacement for standard 0.375-inch shank ball end mill holders and collet systems used in vertical and horizontal machining centers.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully in the collet or holder and torque the retention mechanism per the holder manufacturer specification. Verify runout with a dial indicator before beginning production cuts.
