Hertel E599924532 Ball End Mill 0.4375in 4 Flute Carbide

Product Description

The HERTEL E599924532 is a solid carbide ball end mill designed for precision milling operations in metal cutting and machining applications. With a 0.4375-inch mill diameter, a 0.875-inch length of cut, and a 4-flute configuration, this tool delivers smooth material removal and a quality surface finish in a single-end design. The 30-degree helix angle promotes efficient chip evacuation and reduces chatter during operation. This end mill is manufactured from solid carbide for rigidity and wear resistance, and it ships uncoated for use in applications where specialty coatings are not required. Machinists and CNC operators working in job shops or production environments will find this tool suited to contoured surface work and finish milling passes.

This ball end mill is suited for milling of contoured profiles, 3D surfaces, and radius-bottom slots in ferrous and non-ferrous materials. The right-hand cutting and right-hand flute direction make it compatible with standard CNC machining centers and manual mills running conventional toolpaths. Its single-end construction and consistent geometry support repeatable results in both prototype and production runs.

Key Features

• 0.4375-inch mill diameter with matching 0.4375-inch shank diameter for direct collet or ER chuck mounting
• 4-flute design provides a balance of chip clearance and surface finish quality
• 30-degree helix angle promotes chip flow and reduces cutting forces
• Solid carbide construction offers rigidity and extended tool life compared to HSS alternatives
• Uncoated finish suitable for dry or lubricated cutting in a range of base materials
• Single-end configuration with 2.5-inch overall length for standard reach applications

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills using collet systems or end mill holders accepting a 0.4375-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank fully into a properly sized collet or end mill holder and torque the retention mechanism per the toolholder manufacturer specifications. Inspect the cutting edges for chips or damage before each use. Always confirm spindle speed and feed rate settings against the material being cut before starting the machine.
