Harvey Tool 949416 Drill Mill 1/4 in 2 Flute Solid Carbide

Product Description

The HARVEY TOOL 949416 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 an 82-degree point angle, it transitions cleanly between axial drilling and peripheral milling without a tool change. The 2-flute geometry supports efficient chip evacuation in a variety of workpiece materials. The bright, uncoated finish is well suited to non-ferrous metals, plastics, and composite materials where coating adhesion is not required. Machinists and tooling professionals install this tool in CNC machining centers and manual mills where multi-operation efficiency matters.

This drill mill is suited for light-duty combination drilling and end milling applications in job shop, prototype, and production environments. The 1/4 inch shank diameter fits standard ER collet chucks and end mill holders commonly found on vertical machining centers and CNC routers. The 82-degree point angle is a common geometry for countersinking and spot-drilling operations on softer materials, making this tool useful across a range of secondary operations without additional setup.

Key Features

• Solid carbide construction for rigidity and wear resistance
• 82-degree point angle supports drilling, spot drilling, and countersinking in a single pass
• 2-flute design promotes chip clearance during combined drill-mill operations
• Bright, uncoated finish for use in non-ferrous metals, plastics, and composites
• 1/4 inch shank diameter fits standard collet and end mill holder tooling
• 3/4 inch length of cut allows moderate-depth milling passes

Compatibility

Designed as a direct-fit replacement-style drill mill for CNC machining centers, manual vertical mills, and CNC routers using 1/4 inch ER collet chucks or end mill holders.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully powered down and at a complete stop before inserting or removing the tool from the holder. Verify collet size and holder bore match the 1/4 inch shank diameter before tightening. Follow machine manufacturer torque guidelines for collet nuts and set screws to prevent tool pullout during operation.
