Hertel EG250006 Ball End Mill 3/32 in 4 Flute Solid Carbide

Product Description

The HERTEL EG250006 is a solid carbide ball end mill designed for precision milling operations in metalworking and machining applications. With a 3/32 inch cutting diameter and 4-flute geometry, this tool delivers smooth cutting action and fine surface finishes on hardened steels, stainless steels, and non-ferrous materials. The TiCN (Titanium Carbonitride) coating increases surface hardness and reduces friction, extending tool life in demanding cutting conditions. A 3/8 inch length of cut and 1-1/2 inch overall length make it well suited for tight-clearance profiling, slotting, and contouring work. This end mill is installed and used by machinists, tool-and-die makers, and CNC operators.

This end mill is used in CNC machining centers and manual milling machines for 3D contouring, profiling, and finish milling of complex part geometries. The single-end, right-hand cutting configuration is standard for conventional vertical milling setups. The 1/8 inch shank diameter fits standard collets and tool holders used in precision machine shops handling small-diameter workpieces. Typical applications include die cavities, mold work, and detailed part features requiring a ball-nose geometry.

Key Features

• 3/32 inch ball nose diameter for fine contouring and profiling passes
• 4-flute design promotes smooth surface finish and chip evacuation
• Solid carbide construction provides rigidity and wear resistance over high-speed steel alternatives
• TiCN coating improves surface hardness and reduces built-up edge on ferrous and non-ferrous materials
• Right-hand cut and right-hand flute direction compatible with standard CNC spindle rotation
• Single-end configuration with 1/8 inch shank for use in standard precision collets

Compatibility

Designed as a standard single-end ball nose end mill with a 1/8 inch shank, compatible with collet-style tool holders accepting 1/8 inch shanks on CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Secure the 1/8 inch shank firmly in a clean, undamaged collet or tool holder to the recommended clamping torque specified by the holder manufacturer. Inspect the cutting edges for chips or wear before each use, and verify runout with a dial indicator when precision surface finish is required.
