Hertel E599924513 Ball End Mill 0.0625 in 4 Flute Carbide

Product Description

The HERTEL E599924513 is a solid carbide ball end mill designed for precision milling operations in ferrous and non-ferrous materials. With a 0.0625-inch cutting diameter and a 4-flute geometry, this tool delivers smooth surface finishes in slots, contours, and 3D profiling work. The 30-degree helix angle promotes efficient chip evacuation and reduces cutting forces at the spindle. The uncoated solid carbide construction provides rigidity and edge retention in demanding milling applications. It is a single-end tool, so the full cutting life is concentrated in the ball nose geometry. Machinists and tool-and-die professionals working in job shops, toolrooms, and production environments will recognize this as a standard small-diameter finishing end mill.

This end mill is suited for fine detail milling, die work, and profiling passes where tight tolerances and a high-quality surface finish are required. The small 0.0625-inch diameter makes it appropriate for intricate cavities, narrow channels, and detailed contour work on CNC machining centers and manual mills equipped with high-speed spindles. The 0.1875-inch length of cut limits axial depth of cut, which is typical for small-diameter carbide tools to prevent deflection and breakage. The 1/8-inch shank diameter is compatible with standard collet systems and toolholders used in precision milling setups.

Key Features

• 0.0625-inch (1/16-inch) ball nose cutting diameter for fine detail work
• 4-flute design for improved surface finish and feed rate capability
• Solid carbide construction for rigidity and edge retention
• 30-degree right-hand helix for efficient chip evacuation
• Uncoated finish suitable for a wide range of base materials
• Single-end tool with 1/8-inch shank for standard collet compatibility

Compatibility

Designed as an OEM-style replacement or standard tooling option for CNC machining centers and manual mills using 1/8-inch collets or toolholders requiring a single-end ball end mill.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the tool from the collet or chuck. Confirm the collet bore matches the 1/8-inch shank diameter and that the tool is seated to the proper gage length before tightening. At 0.0625-inch diameter, this tool is fragile — avoid excessive side loads, interrupted cuts without proper feed reduction, or runout that exceeds recommended tolerances for small-diameter carbide.
