Hertel E699924497 Ball End Mill 0.25 in 2 Flute Solid Carbide

Product Description

The HERTEL E699924497 is a solid carbide ball end mill designed for precision milling operations in metalworking and machining applications. With a 0.25 inch diameter and a 0.5 inch length of cut, this two-flute tool delivers clean, accurate profiles in contoured and three-dimensional workpieces. The TiN (titanium nitride) coating increases surface hardness and reduces friction at the cutting edge, extending tool life in ferrous and non-ferrous materials. The 2.0 inch overall length and 0.25 inch shank diameter make it compatible with standard collet and end mill holder setups on vertical machining centers and CNC mills. Installed and operated by machinists and tool-and-die professionals.

This end mill is suited for finish milling, profiling, slotting, and 3D contouring on a wide range of materials including alloy steels, stainless steels, aluminum, and cast iron. The single-end, right-hand cutting configuration with right-hand flute direction makes it a standard choice for conventional CNC milling operations. It is equally applicable in job shop, production, and toolroom environments where tight tolerances and smooth surface finishes are required.

Key Features

• Solid carbide construction provides rigidity and wear resistance compared to HSS tooling
• TiN coating increases hardness and reduces built-up edge in ferrous materials
• Ball end geometry enables 3D contouring, profiling, and radius floor finishing
• Two-flute design improves chip evacuation in slotting and deep cavity work
• Right-hand cut and right-hand helix for standard CNC spindle compatibility
• Single-end configuration for straightforward tool change and indexing

Compatibility

Designed as an OEM-style solid carbide ball end mill for use in standard 0.25 inch collets and end mill holders on vertical machining centers and CNC milling machines.

Installation Notes

Installation should be performed by a qualified machinist. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Secure the end mill to the recommended projection length to minimize deflection and chatter. Confirm spindle direction and programmed feed rates match the right-hand cutting specification before initiating a cut.
