Harvey Tool 985516 Drill Mill 1/4 in 2 Flute Solid Carbide

Product Description

The HARVEY TOOL 985516 is a solid carbide drill mill designed to perform both drilling and milling operations in a single tool. With a 1/4 inch cutting diameter and a 120-degree point angle, it enters material like a drill and can then be used for side milling, slotting, or angled work. The two-flute geometry provides good chip clearance in a variety of materials. The bright, uncoated finish makes it well suited for non-ferrous metals, plastics, and composites where a coating could cause adhesion issues. Machinists and tool and die shops rely on this type of combination tool to reduce setups and tool changes on CNC machining centers and manual mills.

This drill mill is used in precision machining environments where operators need to drill, mill, and chamfer without changing tools. Typical applications include spotting, through-drilling, pocket milling, and angular surface work on aluminum, brass, plastics, and similar softer materials. The 1/4 inch shank diameter fits standard ER collet chucks and end mill holders found on most vertical machining centers and CNC routers. It is sold individually as a single unit.

Key Features

• Combination drill and mill geometry allows drilling and side milling in one tool
• 120-degree point angle for accurate spotting and through-hole entry
• 2-flute design promotes chip evacuation during drilling and slotting operations
• Solid carbide construction provides rigidity and wear resistance
• Bright, uncoated finish suited for non-ferrous metals, plastics, and composites
• Matching 1/4 inch cutting diameter and shank diameter for straightforward toolholding

Compatibility

Designed for use in standard 1/4 inch ER collet chucks and end mill holders on CNC machining centers, CNC routers, and manual knee mills.

Installation Notes

Installation and use of this tool should be performed by a qualified machinist familiar with CNC or manual milling equipment. Ensure the spindle is fully stopped and the machine is powered down before loading or unloading the tool. Verify the collet or toolholder is clean and the tool is seated to the correct depth before tightening. Always confirm runout with a dial indicator before beginning a production cut to maximize tool life and part accuracy.
