Harvey Tool 23108-C3 Ball End Mill 0.125 in 4 Flute Altin

Product Description

The HARVEY TOOL 23108-C3 is a 4-flute solid carbide ball end mill designed for precision milling operations in ferrous and non-ferrous materials. The cutting end measures 0.125 inches in diameter with a 0.107-inch length of cut, making it well suited for tight-radius profiling, contouring, and 3D surface finishing. An AlTiN (aluminum titanium nitride) coating improves heat resistance and extends tool life in high-speed and dry cutting applications. The 1/8-inch shank diameter and 1-1/2-inch overall length fit standard collet toolholding systems used in CNC machining centers and manual mills.

This end mill is intended for use in machine shops, production facilities, and toolroom environments where fine detail work and close-tolerance features are required. Typical applications include die and mold work, small-feature pocket milling, and finish passes on hardened or abrasive materials. The single-end configuration is standard for this diameter class. It is installed and operated by machinists and CNC programmers working with vertical machining centers, high-speed spindles, and similar equipment.

Key Features

• 0.125-inch cutting diameter for small-feature and fine-detail milling
• 0.107-inch length of cut supports shallow-to-moderate depth profiling
• 4-flute geometry provides a balance of chip clearance and surface finish quality
• AlTiN coating enhances heat resistance and tool life in abrasive and hardened materials
• Solid carbide construction delivers rigidity and wear resistance over high-speed tool paths
• Single-end design with 1/8-inch shank fits standard ER and precision collet systems

Compatibility

Designed as an OEM-style solid carbide ball end mill for use in CNC machining centers and manual mills equipped with 1/8-inch collet toolholding.

Installation Notes

This tool is installed by machinists into a compatible collet or toolholder before spindle engagement. Ensure the machine spindle is fully stopped and the control is in an e-stop or tool-change state before loading or removing the tool. Confirm proper collet size and runout before cutting, as small-diameter carbide tools are sensitive to spindle misalignment. Follow shop speeds-and-feeds guidelines for the specific workpiece material and coating type.
