Harvey Tool 27416-C3 Drill Mill 1/4 in 4 Flute Altin Carbide

Product Description

The HARVEY TOOL 27416-C3 is a solid carbide drill mill designed for combined drilling and milling operations in a single tool. It features a 1/4 inch cutting diameter, a 100-degree point angle, and four flutes for efficient chip evacuation. The AlTiN coating improves heat resistance and extends tool life in demanding cutting conditions. With a 3/4 inch length of cut and 2-1/2 inch overall length, this drill mill suits close-tolerance work in confined setups. It is installed and operated by machinists and tooling professionals working on CNC machining centers and manual milling machines.

This drill mill is suited for shops performing multi-function operations where drilling, chamfering, and end milling are required in a single pass. The 1/4 inch shank diameter makes it compatible with standard collet systems and tool holders used in both vertical and horizontal milling setups. The AlTiN finish performs well in ferrous materials and high-temperature alloys. It is appropriate for production and prototype work in aerospace, mold-making, and general precision machining environments.

Key Features

• Solid carbide construction for rigidity and wear resistance
• AlTiN coating for elevated heat resistance and longer tool life in ferrous and high-temp alloys
• 100-degree point angle enables drilling, chamfering, and milling in a single operation
• Four flutes provide efficient chip clearance and a smooth finish
• 3/4 inch length of cut with a 2-1/2 inch overall length for compact, precise reach
• 1/4 inch shank diameter fits standard collet and tool holder systems

Compatibility

Designed as an OEM-style solid carbide drill mill for use in CNC machining centers and manual mills equipped with standard 1/4 inch collets or tool holders.

Installation Notes

This tool is installed and operated by machinists using standard collet chucks or end mill holders rated for the 1/4 inch shank diameter. Verify runout and tool holder condition before use, as carbide tooling is sensitive to lateral loading from worn or out-of-tolerance holders. Follow machine manufacturer guidelines for speeds and feeds appropriate to the workpiece material and coating type. Inspect the cutting edges before each use and replace the tool if chipping or wear is observed.
