Harvey Tool 964400-C3 Corner Radius End Mill 0.1in 4FL

Product Description

The HARVEY TOOL 964400-C3 is a miniature long-flute corner radius end mill designed for precision finishing in ferrous and non-ferrous materials. Built from solid carbide and coated with AlTiN via PVD process, this single-end tool delivers heat resistance and extended tool life in demanding cutting applications. The 0.01-inch corner radius reduces stress concentration at part edges while maintaining tight tolerances. With a 0.1-inch mill diameter, 4 helical flutes, and a 30-degree helix angle, this end mill is suited for machinists and toolroom operators working in tight-clearance, high-precision environments such as die work, mold making, and micro-feature machining.

This end mill fits applications requiring long reach in a small-diameter tool. The 0.5-inch length of cut and 2.5-inch overall length allow access to deep pockets and slots while the 0.125-inch straight-cylindrical shank provides secure clamping in standard collets or toolholders. It is center-cutting and right-hand cutting with a right-hand flute direction, making it compatible with conventional CNC milling setups. Primary workpiece materials include steel, stainless steel, cast iron, non-ferrous metals, and composites, covering ISO material groups P, M, K, N, and O.

Key Features

• Solid carbide construction with AlTiN PVD coating for high-heat and wear resistance
• 0.01-inch corner radius with tolerance of plus 0.001 to minus 0.001 inches for consistent edge geometry
• Long-flute design with 0.5-inch length of cut for deep-pocket reach at 0.1-inch diameter
• 4 helical flutes with 30-degree helix angle optimized for finishing passes
• Center-cutting capability allows plunge entry without a pre-drilled hole
• Right-hand cutting and right-hand flute direction for use on standard CNC machining centers

Compatibility

Designed for use with standard toolholders and collets accepting a 0.125-inch straight-cylindrical shank. Suitable for CNC milling operations on steel, stainless steel, cast iron, non-ferrous metals, and composite materials.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before loading or unloading the tool. Clamp the shank securely in a compatible collet or toolholder to the full recommended insertion depth to prevent tool pullout under cutting load. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and coating type.
