Hertel E599924426 Ball End Mill 0.4375 in 4 Flute Carbide

Product Description

The HERTEL E599924426 is a solid carbide ball end mill designed for precision milling operations in metal cutting and machining applications. With a 0.4375-inch cutting diameter and a 0.875-inch length of cut, this tool delivers accurate profiling, contouring, and 3D surface work. The four-flute, right-hand spiral geometry with a 30-degree helix angle promotes efficient chip evacuation and stable cutting performance. The double-end configuration provides two usable cutting ends, extending the service life of each tool. The uncoated carbide construction suits a broad range of ferrous and non-ferrous workpiece materials. Machinists and CNC operators in job shops, tool rooms, and production environments are the primary users of this end mill.

This end mill is suited for use in vertical and horizontal CNC machining centers, manual mills, and multi-axis equipment where ball-nose geometry is required for profiling, slotting, and finish contouring passes. The 0.5-inch shank diameter provides a secure fit in standard collets and end mill holders. At 4 inches overall length, the tool maintains rigidity for typical reach requirements without excessive deflection. It is appropriate for ferrous alloys, aluminum, and general-purpose materials in both roughing and finishing contexts depending on feed and speed selection.

Key Features

• Ball-nose geometry for profiling, contouring, and 3D surface milling
• Four-flute, right-hand spiral design with 30-degree helix for efficient chip flow
• Double-end construction provides two cutting ends per tool
• Solid carbide construction for rigidity and wear resistance
• Uncoated finish suitable for a wide range of workpiece materials
• 0.5-inch shank diameter fits standard collet and end mill holder systems

Compatibility

Designed as an OEM-style replacement and standard-fit cutting tool for CNC machining centers and manual mills accepting a 0.5-inch shank diameter end mill holder or collet.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully powered down and at a complete stop before changing tooling. Seat the shank fully into the collet or holder to the recommended engagement depth and torque the retention mechanism according to the machine tool manufacturer specifications. Verify tool runout with a dial indicator before beginning cuts to confirm proper seating and avoid premature tool wear or workpiece damage.
