Hertel E5062901 Ball End Mill 0.25 in 4 Flute Carbide

Product Description

The HERTEL E5062901 is a solid carbide ball end mill designed for precision milling operations in metalworking and machining environments. Built with a 0.25 inch diameter and a 1.5 inch length of cut, this single-end tool delivers consistent performance in profiling, contouring, and finishing passes. The 4-flute configuration supports efficient chip evacuation while maintaining a strong cutting edge. With a 30-degree helix angle and right-hand cutting and flute direction, it is well suited for general-purpose milling in steel, aluminum, and similar materials. Machinists and CNC operators in job shops, tool rooms, and production environments are the primary users of this end mill.

This ball end mill is applicable in both manual and CNC milling setups where a 0.25 inch shank is required. The 6 inch overall length provides extended reach for deeper pockets and profiled surfaces without sacrificing rigidity at this diameter. The uncoated solid carbide construction makes it a reliable choice for shops that regrind tooling or prefer uncoated substrates for specific workpiece materials. It is a single-end tool, meaning it is not reversible and should be replaced when the cutting end is worn.

Key Features

• 0.25 inch cutting diameter with a matching 0.25 inch shank for direct collet or end mill holder fitment
• 1.5 inch length of cut suitable for profiling and contouring operations
• 4-flute design balances material removal rate with surface finish quality
• 30-degree helix angle promotes smooth cutting action and chip flow
• Solid carbide construction provides hardness and wear resistance over high-speed steel alternatives
• Uncoated finish compatible with regrinding services and dry or lubricated cutting conditions

Compatibility

Designed as an OEM-style replacement or direct-application solid carbide ball end mill for standard 0.25 inch collet chucks and end mill holders used in CNC machining centers and manual knee mills.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill from the holder. Use a properly sized collet or end mill holder that matches the 0.25 inch shank diameter to prevent runout and premature tool wear. Verify tool projection and reach requirements before beginning a cut, and follow applicable shop safety standards for rotating tooling.
