Hertel E599924516 Ball End Mill 0.125 in 4 Flute Carbide

Product Description

The HERTEL E599924516 is a solid carbide ball end mill designed for precision milling operations in metal, alloy, and composite materials. Built with 4 flutes and a 30-degree helix angle, this tool delivers efficient chip evacuation and smooth cutting action in both roughing and finishing passes. The ball nose geometry produces contoured, curved, and radius-profiled features that flat-end mills cannot achieve. With a 0.125-inch diameter and 0.25-inch length of cut, this tool is suited for fine-detail work, die and mold cavities, and small-part machining where dimensional accuracy is critical. Machinists and tool-and-die professionals are the primary users.

This end mill is intended for use in CNC machining centers and manual mills handling precision components in aerospace, automotive, mold-making, and general metalworking applications. The 0.125-inch shank diameter fits standard collet systems, and the 1.5-inch overall length provides adequate reach for most shallow-pocket and contour-milling setups. The uncoated solid carbide construction makes it well suited for dry cutting or applications where coating compatibility with the workpiece material is a concern.

Key Features

• Ball nose geometry for contouring, radius profiling, and cavity milling
• 4-flute design promotes surface finish quality and feed rate capability
• 30-degree right-hand helix for efficient chip flow and reduced cutting forces
• Solid carbide construction for rigidity and wear resistance
• Uncoated finish suitable for a wide range of base materials
• Single-end tool with right-hand cutting direction

Compatibility

Designed as a direct-fit replacement for 0.125-inch diameter ball end mills in standard collet-style CNC machining centers and manual milling machines accepting a 0.125-inch shank.

Installation Notes

Installation should be performed by a qualified machinist familiar with tool-holder torque procedures and runout verification. Ensure the spindle is fully powered down and locked before changing tooling. Seat the shank fully into the collet or end mill holder and verify tool runout with a dial indicator before beginning a cut. Follow machine-builder guidelines and applicable shop safety standards when setting tool offsets and feed-rate parameters.
