Harvey Tool 24623-C3 Ball End Mill 0.0230 in 4 Flute Carbide

Product Description

The HARVEY TOOL 24623-C3 is a miniature solid carbide ball end mill designed for high-precision milling in tight-tolerance applications. With a 0.0230-inch mill diameter and a 0.90 mm length of cut, this stub-length tool is built for small-feature work where rigidity and accuracy are critical. The 4-flute, right-hand spiral geometry with a 30-degree helix angle promotes efficient chip evacuation and smooth surface finishes. An AlTiN (aluminum titanium nitride) PVD coating extends tool life when cutting ferrous materials. Licensed machinists and CNC programmers working in precision shops are the primary users of this tool.

This end mill is suited for roughing and finishing operations on steel, stainless steel, and cast iron. The stub length configuration minimizes deflection, making it appropriate for micro-milling on vertical machining centers and CNC mills where workpiece features are small and tolerances are tight. The straight cylindrical shank at 0.1250 inches accommodates standard 1/8-inch collets or tool holders commonly found in precision machining setups. The single-end design and 1.5-inch overall length make it a practical choice for small-part production runs.

Key Features

• 0.0230-inch ball nose diameter with a nose radius of 0.0115 inches for accurate small-radius contouring
• 4-flute right-hand spiral with 30-degree helix angle for improved chip flow and surface finish
• AlTiN PVD coating rated for steel, stainless steel, and cast iron cutting
• Stub length design reduces deflection in tight-clearance and micro-milling operations
• Mill diameter tolerance of plus 0.0005 / minus 0.0005 inches for tight dimensional control
• Solid carbide construction provides rigidity and wear resistance at small diameters

Compatibility

Designed for use in 1/8-inch collets and compatible tool holders on CNC vertical machining centers. Primary workpiece materials are steel, stainless steel, and cast iron, consistent with ISO material groups P, M, and K.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Use the appropriate collet torque specifications provided by the tool holder manufacturer. At this diameter, runout control is critical — verify TIR at the tool holder before running the program.
