Harvey Tool 52831 Ball End Mill 0.0312 in 2 Flute Carbide

Product Description

The HARVEY TOOL 52831 is a solid carbide ball end mill designed for high-precision milling operations in demanding metalworking and machining applications. With a 0.0312-inch cutting diameter and a 0.0265-inch length of cut, this micro-end mill is built for small-feature detail work including slots, contours, and profiling passes where tight tolerances are required. The 2-flute geometry supports efficient chip evacuation in confined cutting zones. At 1.5 inches overall length with a 0.125-inch shank diameter, it mounts in standard collet toolholding systems. The uncoated solid carbide construction delivers consistent hardness and edge retention across a range of workpiece materials. Machinists and CNC operators working in tool rooms, prototype shops, and production cells rely on this geometry for micro-scale work.

This end mill is suited for small-feature milling in materials such as aluminum, brass, plastics, and softer steels. The ball nose profile makes it appropriate for 3D contouring, ramp entry, and radius-floor pocket work on CNC machining centers and high-speed spindle setups. The compact OAL and narrow shank diameter make it a natural fit for micro-milling fixtures where clearance is limited. Single-end configuration means the tool is replaced rather than reindexed at end of life.

Key Features

• 0.0312-inch ball nose cutting diameter for micro-feature milling
• 0.0265-inch length of cut for shallow slot and contour work
• 2-flute design promotes chip clearance in tight cutting zones
• Solid carbide construction for hardness and edge stability
• Uncoated finish suitable for a broad range of base materials
• 1.5-inch OAL with 0.125-inch shank for standard collet compatibility

Compatibility

Designed as an OEM-style replacement and standard-geometry ball end mill for CNC machining centers and manual mills equipped with collet toolholding that accepts a 0.125-inch shank diameter.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully powered down and the tool changer or spindle is at a safe rest position before handling micro end mills of this diameter. Secure the shank fully within the collet to the recommended gauge-line depth before torquing the collet nut. At this diameter, runout control is critical - inspect collet condition and clean the taper before seating the tool.
