Harvey Tool 29516-C3 Ball End Mill 0.25 in 4 Flute Altin

Product Description

The HARVEY TOOL 29516-C3 is a solid carbide ball end mill designed for high-precision milling operations in ferrous and non-ferrous materials. With a 0.25-inch mill diameter and a 0.213-inch length of cut, this tool is built for tight-tolerance profiling, contouring, and finishing passes in CNC machining centers. The AlTiN coating provides thermal resistance and hardness for extended tool life in demanding cuts. Four right-hand flutes with a 270-degree wrap angle improve chip evacuation and surface finish. This end mill is suited for machinists and tooling technicians running production or prototype work.

This end mill is used in vertical and horizontal CNC machining centers for 3D contouring, die and mold work, and finish milling of slots and profiles. The 0.158-inch neck diameter and 1.5-inch neck length allow access to deeper cavities without tool deflection. The 0.25-inch shank seats directly into standard ER or end mill holders. It is appropriate for both production shops and job shops working with hardened steels, stainless, titanium, and similar alloys where heat resistance is critical.

Key Features

• Solid carbide construction for rigidity and long tool life in hard materials
• AlTiN coating provides high thermal resistance and wear resistance during aggressive cuts
• 4-flute, right-hand cutting configuration for efficient chip removal and fine surface finish
• 270-degree wrap angle supports smooth contouring and full ball engagement
• Reduced neck diameter of 0.158 inches enables deep-cavity reach with minimized deflection
• Single-end design with 4-inch overall length for consistent tool length offset setup

Compatibility

Designed as an OEM-style solid carbide ball end mill compatible with standard 0.25-inch shank end mill holders and collet chucks on CNC machining centers.

Installation Notes

Installation is performed by qualified CNC machinists or tooling technicians. Seat the shank fully into the holder to the recommended gauge line before torquing the retention mechanism to the holder manufacturer specification. Verify tool length offset in the machine controller before cutting. Inspect the cutting edge and coating for chips or wear before each use, as carbide tooling is brittle and should not be used if edge damage is present.
