Harvey Tool 823462-C3 Ball End Mill 0.062 in 3 Flute Altin

Product Description

The HARVEY TOOL 823462-C3 is a miniature solid carbide ball end mill designed for precise milling operations in ferrous and hard materials. At 0.062 inches in diameter with a 0.093-inch length of cut, this stub-length tool delivers tight-tolerance performance in confined geometries. The three-flute, right-hand helical design with a 30-degree helix angle promotes efficient chip evacuation while maintaining a smooth finish surface. An AlTiN (aluminum titanium nitride) PVD coating increases surface hardness and thermal resistance, making this tool well suited for dry or near-dry cutting in steel, stainless steel, and cast iron. Licensed machinists and CNC programmers specify this geometry for detailed finish work and light roughing in a single operation.

This end mill is intended for use in CNC machining centers, high-speed spindles, and precision manual mills where small-diameter tooling is required. Its stub length minimizes deflection during fine-detail passes, making it a practical choice for mold and die work, aerospace components, and medical device features machined from steel and stainless steel. The straight cylindrical shank at 0.125 inches diameter fits standard collet systems. Primary workpiece materials rated for this tool include steel, stainless steel, and cast iron. It is a single-end tool and does not include coolant-through capability, so external coolant or air blast is the standard approach.

Key Features

• 0.062-inch ball end diameter with a 0.031-inch nose radius for precise contoured surfaces
• Three right-hand helical flutes at 30-degree helix angle for balanced cutting and chip flow
• AlTiN PVD coating for elevated thermal resistance and extended tool life in ferrous materials
• Stub length (0.093-inch reach, 1.5-inch OAL) minimizes deflection in tight-tolerance cuts
• Solid carbide construction throughout for rigidity at small diameters
• Rated for roughing and finishing in a single tool — reduces changeover in multi-step programs

Compatibility

Designed for machining steel, stainless steel, and cast iron (ISO material codes P, M, and K). Fits any collet or chuck system accepting a 0.125-inch straight cylindrical shank. Part of the Harvey Tool Miniature End Mills Ball Stub and Standard series.

Installation Notes

Installation and tool changes should be performed by a qualified machinist or CNC operator with the spindle fully stopped and the machine in an e-stop or lockout state. Confirm collet size and runout before seating the shank — excessive runout at this diameter accelerates edge wear and increases breakage risk. Do not use this tool beyond its rated reach of 0.093 inches without verifying deflection limits. Follow the tool manufacturer programming guidelines for feed rate and depth of cut at this diameter; no specific values are provided here.
