Harvey Tool 824016 Drill Mill 1/4 in 4 Flute 90 Pt Carbide

Product Description

The HARVEY TOOL 824016 is a solid carbide drill mill designed to perform both drilling and end milling operations in a single tool. With a 1/4 inch cutting diameter, a 90-degree point angle, and four flutes, it handles center drilling, spot drilling, chamfering, and peripheral milling without a tool change. The uncoated bright finish suits general-purpose machining in a wide range of materials. The 1-1/4 inch length of cut and 4 inch overall length provide the reach needed for most standard milling setups. Machinists and tool-and-die professionals rely on this geometry for efficient multi-operation work in CNC machining centers and manual mills.

This drill mill is suited for job shops, production machining, and toolroom applications where minimizing tool changes improves cycle time. The 1/4 inch shank diameter fits standard ER collets, end mill holders, and drill chucks commonly found in vertical machining centers and knee mills. It is appropriate for use in ferrous and non-ferrous metals, plastics, and composites where a combined drill-and-mill approach is practical.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cutting applications
• 90-degree point angle enables spot drilling, center drilling, and chamfering in the same operation as peripheral milling
• Four flutes provide good chip evacuation and a smooth finish on milled surfaces
• Uncoated bright finish compatible with a broad range of workpiece materials without coating-compatibility concerns
• Equal shank and cutting diameter (1/4 inch) simplifies toolholding and reduces runout risk
• 4 inch overall length fits standard toolholders without extended-reach accessories in most applications

Compatibility

Designed as an OEM-style replacement and direct-fit drill mill for CNC machining centers, knee mills, and drill presses accepting 1/4 inch shank toolholders including ER collet systems and end mill holders.

Installation Notes

Installation should be performed by a qualified machinist familiar with rotary cutting tool safety. Ensure the machine spindle is fully stopped and locked out before changing or seating the tool in the holder. Inspect the shank and collet bore for chips or damage before tightening to manufacturer-specified torque using the appropriate spanner wrench. Verify runout with a dial indicator before beginning a production cut, and confirm spindle speed and feed rate are appropriate for the workpiece material before engaging the tool.
