Harvey Tool 824216-C3 Drill Mill 1/4 in 4 Flute Altin Carbide

Product Description

The HARVEY TOOL 824216-C3 is a solid carbide drill mill designed for operations that require both drilling and milling in a single tool. With a 1/4 inch diameter, a 90-degree point angle, and four flutes, this tool handles center drilling, spotting, chamfering, and peripheral milling without a tool change. The AlTiN (aluminum titanium nitride) coating improves heat resistance and extends tool life in ferrous and hard alloy materials. Overall length is 4 inches with a 3/4 inch length of cut. Machinists and CNC programmers in production and job shop environments rely on this geometry for multi-function tool paths that reduce setup time.

This drill mill is suited for use in vertical machining centers, CNC mills, and manual knee mills. It is appropriate for applications in steel, stainless steel, cast iron, and high-temperature alloys where the AlTiN finish provides thermal protection. The 90-degree point angle makes it effective for spot drilling to angle, countersinking, and generating chamfers on through-holes or part edges. The 1/4 inch shank diameter fits standard ER collet chucks, end mill holders, and shrink-fit tooling systems commonly used in production machining.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating for elevated heat resistance and extended tool life in ferrous alloys
• 90-degree point angle for spot drilling, chamfering, and countersinking operations
• Four-flute design balances chip evacuation with cutting edge strength
• 1/4 inch shank diameter compatible with standard collet and end mill holder systems
• Combines drilling and milling capability to reduce tool changes in multi-operation setups

Compatibility

Designed as an OEM-style solid carbide drill mill for use in standard 1/4 inch shank toolholders including ER collet chucks and end mill holders on CNC and manual milling machines.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and the control is in an e-stop or lockout state before loading or unloading the tool. Secure the shank fully within the holder to the recommended engagement depth for the collet or holder in use. Verify runout with a dial indicator after seating to avoid premature tool wear or workpiece dimensional error.
