Harvey Tool 824016-C3 Drill Mill 1/4 in 4 Flute Altin Carbide

Product Description

The HARVEY TOOL 824016-C3 is a solid carbide drill mill designed for combined drilling and milling operations in a single tool. With a 1/4 inch diameter, a 90-degree point angle, and four flutes, it handles center drilling, spotting, chamfering, and full-slot milling without a tool change. The AlTiN (aluminum titanium nitride) coating extends tool life in harder workpiece materials by improving heat resistance and surface hardness. This tool is sized for CNC machining centers and manual mills where precision and efficiency matter. Machinists and tool-and-die professionals are the primary users.

The 824016-C3 is suited for metalworking applications in job shops, production machining environments, and toolrooms. Its 1/4 inch shank diameter fits standard ER collet chucks and end mill holders commonly found on vertical machining centers and milling machines. The 1-1/4 inch length of cut provides adequate flute engagement for through-holes and shallow pockets in steel, stainless steel, aluminum, and other machinable metals where the AlTiN coating provides a performance advantage over uncoated tooling.

Key Features

• Four-flute geometry balances chip evacuation with rigidity for both drilling and milling
• 90-degree point angle is standard for spotting, centering, and chamfering operations
• AlTiN coating improves heat resistance and tool life in ferrous and hardened materials
• Solid carbide construction provides stiffness and wear resistance beyond high-speed steel alternatives
• 1/4 inch shank diameter fits standard collet chucks and end mill holders
• 1-1/4 inch length of cut supports shallow-to-moderate depth pocket and drilling work

Compatibility

Designed for use in standard 1/4 inch ER collet chucks, end mill holders, or equivalent toolholding systems on CNC vertical machining centers, knee mills, and similar milling equipment.

Installation Notes

Installation and use of this tool should be performed by qualified machinists familiar with cutting tool safety practices. Ensure the machine spindle is fully stopped and the tool holder is properly torqued before beginning any operation. Verify runout with a dial indicator after installation to protect both the tool and the workpiece. Follow the machine manufacturer and tooling supplier guidelines for feeds, speeds, and coolant application appropriate to the workpiece material.
