Harvey Tool 29516 Ball End Mill 0.25 in 4 Flute Carbide

Product Description

The HARVEY TOOL 29516 is a solid carbide ball end mill designed for precision milling operations in metal, composites, and other hard materials. With a 0.25-inch cutting diameter and a 0.213-inch length of cut, this tool delivers accurate ball-nose profiling, contouring, and 3D surface work. The 4-flute geometry provides a strong core and smooth finish at higher feed rates. At 4 inches overall length with a 0.25-inch shank diameter, it fits standard CNC mill and VMC toolholders. The uncoated carbide construction makes it well-suited for applications where coating compatibility or regrinding is a consideration. Machinists and CNC programmers install this tool in production and job-shop environments.

The 29516 is suited for finish milling, profiling, and contour work on molds, dies, and precision components. Its compact length of cut makes it appropriate for shallow pocket work and surface finishing passes where rigidity and deflection control matter. The single-end configuration means the tool is replaced rather than flipped when worn. It is typically run in CNC machining centers, knee mills, and similar equipment requiring precise ball-nose geometry.

Key Features

• 0.25-inch ball nose cutting diameter for accurate radius profiling
• 0.213-inch length of cut suited for shallow contouring and finish passes
• 4-flute design supports higher feed rates and improved surface finish
• Solid carbide construction for rigidity and wear resistance in hard materials
• Uncoated finish for versatile use and regrindability
• Single-end, 4-inch overall length with standard 0.25-inch shank

Compatibility

Designed as an OEM-style replacement or standard production ball end mill for CNC machining centers and manual mills accepting a 0.25-inch shank diameter toolholder.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Always power down the spindle and confirm zero-energy state before changing tooling. Use a properly sized collet or end mill holder torqued per the toolholder manufacturer specification to prevent slippage. Inspect the shank and cutting edges for damage before each use and discard any tool showing chipping or runout beyond acceptable limits.
