Hertel EG250064 Ball End Mill 1 in 4 Flute Solid Carbide

Product Description

The HERTEL EG250064 is a solid carbide ball end mill designed for high-precision milling operations in metalworking and machining applications. With a 1 inch cutting diameter and a 1.5 inch length of cut, this single-end tool delivers consistent performance on contoured surfaces, pockets, and 3D profiling work. The four-flute geometry and TiCN (titanium carbonitride) coating increase surface hardness and reduce friction, extending tool life in ferrous and non-ferrous materials. At 4 inches overall length and a 1 inch shank diameter, it is sized for rigid setups on vertical and horizontal machining centers. Machinists and CNC operators install this tool where dimensional accuracy and finish quality are critical.

This end mill is suited for milling operations in job shops, production facilities, and tool rooms. It handles contour milling, die and mold work, and finish passes on hardened materials where a ball nose profile is required. The right-hand cutting and right-hand flute direction are standard for conventional CNC spindle configurations. The single-end design is typical for carbide tooling where rigidity and runout control are priorities over reversibility.

Key Features

• 1 inch mill diameter with 1.5 inch length of cut for deep-reach milling
• 4-flute solid carbide construction for rigidity and chip load capacity
• TiCN coating increases wear resistance and reduces built-up edge in ferrous materials
• Right-hand cut and right-hand flute direction compatible with standard CNC spindles
• 1 inch shank diameter for secure toolholder engagement with minimal runout
• Single-end design for maximum core strength at full 4 inch overall length

Compatibility

Designed as a direct-fit solid carbide ball end mill for standard 1 inch bore toolholders, collet chucks, and shrink-fit holders used on vertical and horizontal CNC machining centers.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the spindle before changing tooling. Seat the shank fully into the toolholder to the recommended engagement depth and torque the retention mechanism per the toolholder manufacturer specifications. Inspect the cutting edges and coating for chips or damage before each use, and verify runout with a dial indicator before beginning a production run.
