Hertel EG99924513 Ball End Mill 0.0625 in 4 Flute Carbide

Product Description

The HERTEL EG99924513 is a solid carbide ball end mill designed for precision milling operations in metal, composite, and hard material applications. With a 0.0625 inch cutting diameter and a 0.1875 inch length of cut, this end mill is built for small-feature profiling, slotting, and contouring where tight tolerances are required. The four-flute geometry increases chip load per revolution and improves surface finish compared to two-flute designs. A TiCN (titanium carbonitride) coating adds surface hardness and reduces tool wear, making it well-suited for ferrous and non-ferrous materials. Machinists and tool-and-die professionals rely on this class of end mill for die cavities, mold details, and fine finish passes.

This end mill is appropriate for CNC machining centers and manual mills handling small-bore profiling, engraving, and detailed 3D contouring. The 0.0625 inch diameter targets tight-radius features and narrow slot geometry. The 1/8 inch shank diameter accommodates standard collet toolholders commonly found in vertical machining centers and high-speed spindles. Single-end construction means the tool is replaced rather than flipped when the cutting edge is worn. Typical users include precision machinists, mold makers, aerospace fabricators, and job shop operators working with hardened steels, aluminum alloys, and similar materials.

Key Features

• 0.0625 inch ball end cutting diameter for small-feature and tight-radius work
• Four-flute design improves surface finish and increases material removal rate
• Solid carbide construction provides rigidity and resistance to deflection at small diameters
• TiCN coating increases surface hardness and extends tool life in ferrous and non-ferrous materials
• Right-hand cut and right-hand flute direction for standard CNC spindle compatibility
• Single-end configuration with 1/8 inch shank fits standard collet toolholders

Compatibility

Designed for use in CNC machining centers and manual mills equipped with collet toolholders accepting a 1/8 inch shank diameter. Suitable for profiling, slotting, and contouring operations in materials including hardened steels, aluminum, and composites.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. The shank should be fully seated in the collet to the recommended engagement depth to minimize runout and deflection. At 0.0625 inch diameter, solid carbide end mills are susceptible to breakage from excessive feed rates, improper clamping, or lateral shock — verify feeds and speeds before engaging the cut.
