Hertel EG99924515 Ball End Mill 0.0938 in 4 Flute Carbide

Product Description

The HERTEL EG99924515 is a solid carbide ball end mill designed for precision milling of contoured surfaces, slots, and complex 3D profiles. With a 0.0938-inch cutting diameter and four flutes, it delivers fine material removal and smooth surface finishes in hardened steels, stainless steel, cast iron, and non-ferrous metals. The TiCN coating extends tool life by increasing surface hardness and reducing friction at the cutting edge. At 1.5 inches overall length with a 0.125-inch shank diameter, this is a compact, high-rigidity tool suited for tight-tolerance work in CNC machining centers and manual mills.

This end mill is used in tool and die, mold making, aerospace component machining, and general precision metalworking applications. The single-end, right-hand cut and right-hand flute configuration suits conventional CNC vertical milling operations. Its 0.1875-inch length of cut makes it appropriate for shallow pocket and profile work where tool overhang must be minimized to control deflection and maintain dimensional accuracy.

Key Features

• 0.0938-inch ball nose diameter for fine contour and 3D surface milling
• Four-flute design increases feed rate capability and improves surface finish
• Solid carbide construction provides rigidity and wear resistance over high-speed steel alternatives
• TiCN coating improves hardness and reduces built-up edge on ferrous and non-ferrous materials
• Right-hand cut and right-hand helix for standard CNC spindle compatibility
• Single-end configuration with 0.125-inch shank diameter for standard collet and end mill holder fitment

Compatibility

Designed as a direct-fit replacement or standard addition for CNC machining centers and manual mills using 1/8-inch collets or end mill holders. Compatible with standard ER11, ER16, and similarly sized collet systems that accept a 0.125-inch shank diameter.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the spindle before inserting or removing the tool from the collet or end mill holder. Ensure the shank is fully seated and the collet nut is torqued to the tool holder manufacturer's specification. Inspect the cutting edges for chips or coating damage before use, as micro-diameter carbide tools are brittle and sensitive to improper handling or excessive runout.
