Harvey Tool 31316-C6 Square End Mill 1/4 in 4 Flute Altin Carbide

Product Description

The HARVEY TOOL 31316-C6 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous materials. With a 1/4 inch cutting diameter, 4 flutes, and an AlTiN coating, this tool delivers extended tool life in high-temperature cutting environments. The 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces. At 4 inches overall length with a 1-1/2 inch reach length, this end mill is built for extended-reach applications where standard tools cannot access. Single-end configuration with center-cutting capability allows for both plunge and peripheral milling. Installed by machinists and tool-and-die professionals in CNC machining centers and manual mills.

This end mill suits applications requiring extended reach into deep pockets, slots, or cavities in mold work, die making, and precision part machining. The 3/8 inch shank diameter provides solid tool holding in standard ER collets and end mill holders. Center-cutting geometry allows direct plunge entry. Right-hand cut and right-hand flute direction are standard for conventional CNC setups. The AlTiN coating performs well in dry or near-dry cutting conditions on hardened steels, stainless steels, and cast iron where heat resistance is critical.

Key Features

• 1/4 inch cutting diameter with 3/8 inch length of cut for precision slot and pocket work
• AlTiN coating for high-temperature resistance and extended tool life in ferrous materials
• 30-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Extended reach design with 1-1/2 inch reach length for deep-cavity applications
• Center-cutting capable — supports direct plunge milling without a pre-drilled entry hole
• Solid carbide construction provides rigidity and wear resistance over high-speed tool steel alternatives

Compatibility

Designed for use in CNC machining centers and manual mills with standard 3/8 inch collet or end mill holder tooling. Suitable for right-hand spindle rotation setups.

Installation Notes

Installation should be performed by a qualified machinist following shop-standard toolholding procedures. Ensure the shank is fully seated and secured in the collet or end mill holder before operation. Confirm spindle direction is set to right-hand rotation before engaging the workpiece. Inspect the tool for chips or coating damage prior to each use and replace if edge integrity is compromised.
