Hertel EG250032 Ball End Mill 0.5 in 4 Flute Carbide Ticn

Product Description

The HERTEL EG250032 is a single-end ball end mill designed for precision milling operations in metal cutting and finishing applications. Built from solid carbide, it delivers superior hardness and wear resistance compared to high-speed steel tooling. The cutting end is coated with titanium carbonitride (TiCN), which increases surface hardness and reduces friction during cut, extending tool life in ferrous and non-ferrous materials. With a 0.5 inch diameter, 1 inch length of cut, and 4-flute geometry, this end mill is suited for finishing passes, contour milling, and 3D profile work where smooth surface finish is required.

This end mill is used in CNC machining centers and manual milling machines for profiling, slotting, and contouring operations. The ball nose geometry makes it appropriate for die and mold work, curved surface finishing, and ramp-entry cuts. The right-hand cutting direction and right-hand flute spiral are standard for the majority of vertical milling setups. It is sized for a 0.5 inch collet or end mill holder and is a single-end design, meaning it is replaced rather than flipped when the cutting end is worn.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cutting conditions
• TiCN coating increases surface hardness and reduces built-up edge on the cutting lips
• 4-flute configuration supports higher feed rates and improved surface finish on finishing passes
• Ball end geometry suited for contour milling, 3D profiling, and die and mold applications
• Right-hand cut and right-hand helix for use in standard CNC and manual vertical mills
• Single-end design with 0.5 inch shank fits standard collet chucks and end mill holders

Compatibility

Designed as a direct-fit replacement for 0.5 inch diameter ball end mills in standard 0.5 inch collet chucks and end mill holders used on CNC machining centers and vertical milling machines.

Installation Notes

Installation is performed by machinists using a calibrated torque wrench and appropriate collet or end mill holder rated for the shank diameter. Ensure the machine spindle is fully powered down and locked out before changing tooling. The shank should be cleaned of chips and coolant residue before seating in the holder to prevent runout. Follow the machine tool manufacturer guidelines for pull-out force and drawbar torque when securing the tool holder.
