Harvey Tool 24625-C3 Ball End Mill 0.025 in 4 Flute Carbide

Product Description

The HARVEY TOOL 24625-C3 is a miniature solid carbide ball end mill designed for high-precision milling in steel, stainless steel, and cast iron. The tool features a 0.0250-inch cutting diameter with a 0.0370-inch length of cut and a nose radius of 0.0125 inches, making it well suited for fine-detail work and tight-tolerance contouring. The 4-flute, right-hand spiral configuration with a 30-degree helix angle supports both roughing and finishing operations in a single pass. An AlTiN PVD coating provides thermal resistance and extended tool life in ferrous and hard materials. The 1/8-inch straight cylindrical shank fits standard collet chucks. Machinists and toolroom technicians install this end mill in CNC machining centers and manual mills where stub-length rigidity is required.

This end mill is categorized within the HARVEY TOOL Miniature End Mills Ball Stub and Standard series. It is intended for use in applications where a small-diameter, short-reach tool is necessary to maintain rigidity and minimize deflection. Typical use cases include contour milling, profiling, and finishing passes in steel, stainless steel, and cast iron workpieces. The stub length geometry reduces tool overhang and is favored in die and mold work, medical component machining, and precision aerospace part production where dimensional accuracy is critical.

Key Features

• 0.0250-inch ball end cutting diameter with plus or minus 0.0005-inch diameter tolerance
• Solid carbide construction for rigidity and wear resistance in hard ferrous materials
• AlTiN PVD coating for high-temperature performance and extended tool life
• 4-flute right-hand spiral design supports both roughing and finishing in one tool
• 30-degree helix angle promotes efficient chip evacuation in steel and stainless steel
• Stub length configuration minimizes deflection in tight-tolerance or deep-pocket work

Compatibility

Designed for use with standard 1/8-inch collet chucks and tool holders on CNC machining centers and manual mills. Primary workpiece materials are steel, stainless steel, and cast iron.

Installation Notes

Installation is performed by a machinist or toolroom technician using a compatible collet chuck or end mill holder sized for a 1/8-inch shank. Ensure the machine spindle is fully stopped and locked before inserting or removing the tool. Verify collet condition and holding torque per the toolholder manufacturer specifications before running. Use appropriate speeds and feeds for the workpiece material and cutting diameter to avoid tool breakage at this miniature scale.
