Harvey Tool 15416 Drill Mill 1/4 in 4 Flute Solid Carbide

Product Description

The HARVEY TOOL 15416 is a solid carbide drill mill designed for combined drilling and milling operations in a single tool. With a 1/4 inch cutting diameter and a 60-degree point angle, it enters the workpiece cleanly before transitioning into side milling without a tool change. The 4-flute geometry provides stability and improved surface finish during peripheral milling passes. An uncoated bright finish makes the tool well-suited for applications where coating interaction with the workpiece material is a concern. Machinists and CNC operators install this tool in standard collet chucks or end mill holders on vertical machining centers and CNC mills.

This drill mill is used in general metalworking and precision machining environments where a single tool must handle both center drilling and end milling in the same setup. The 3/4 inch length of cut and 2-1/2 inch overall length suit it to shallow-to-medium-depth pockets, slots, and chamfered entry holes. It is a common choice for prototype shops and production lines that prioritize reducing tool changes and maintaining tight positional tolerances between drilled and milled features.

Key Features

• Solid carbide construction for rigidity and wear resistance in metalworking applications
• 60-degree point angle enables combined drilling and chamfering in one pass
• 4-flute design improves finish quality and cutting stability during milling
• Uncoated bright finish suitable for a wide range of workpiece materials
• 1/4 inch shank diameter fits standard collet and end mill holder systems
• 3/4 inch length of cut with 2-1/2 inch overall length for shallow-to-medium feature depths

Compatibility

Designed as an OEM-style replacement or direct-use drill mill for CNC machining centers and manual mills accepting 1/4 inch shank tooling in standard ER or end mill collet systems.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank fully within the collet or tool holder to the recommended engagement depth and torque the collet nut according to the holder manufacturer specifications before running the spindle. Confirm spindle runout with a dial indicator before cutting to protect the tool and workpiece. Do not exceed the tool's rated cutting parameters for the material being machined.
