Harvey Tool 74031 Ball End Mill 0.031 in 2 Flute Carbide

Product Description

The HARVEY TOOL 74031 is a miniature solid carbide ball end mill designed for precision milling in tight geometries and small-feature work. With a 0.031 inch cutting diameter and a 0.093 inch length of cut, this tool is built for fine detail passes in steel, stainless steel, cast iron, and non-ferrous metals. The 2-flute, right-hand helical geometry with a 30-degree helix angle promotes chip evacuation and maintains edge integrity at small diameters. It ships uncoated with a bright finish, making it a reliable choice for shops that prefer uncoated carbide in controlled cutting environments.

This end mill is suited for CNC machining centers and high-speed spindle applications where small-radius contours, slots, and 3D surface work are required. The 0.125 inch straight cylindrical shank fits standard collets and tool holders. With a 1.5 inch overall length and standard stub reach, it provides rigidity at this diameter. Machinists working in tool-and-die, mold making, medical component fabrication, and precision aerospace work will find this tool applicable for both roughing and finishing passes on small features.

Key Features

• 0.031 inch ball nose diameter with a nose radius of 0.0155 inches for precise small-radius contouring
• Solid carbide construction for rigidity and wear resistance at miniature diameters
• 2-flute right-hand helical design with 30-degree helix angle promotes chip flow
• Uncoated bright finish suitable for a range of workpiece materials including non-ferrous metals
• Single-end configuration with 1.5 inch overall length and 0.125 inch shank diameter
• Rated for both roughing and finishing material removal

Compatibility

Designed for use with steel, stainless steel, cast iron, and non-ferrous metals. Fits standard 0.125 inch collets and end mill holders on CNC machining centers. Part of the Harvey Tool Miniature End Mills series.

Installation Notes

Install and remove end mills only with the spindle fully powered down and the machine in a safe, locked-out state. Ensure the collet and tool holder are clean and free of debris before seating the shank to full engagement depth. At miniature diameters, runout tolerance is critical — verify TIR with a dial indicator before cutting. Handle solid carbide tools carefully to avoid chipping the cutting edges during setup.
