Harvey Tool 15416-C3 Drill Mill 1/4 in 4 Flute Altin Carbide

Product Description

The HARVEY TOOL 15416-C3 is a solid carbide drill mill designed for machinists and tooling professionals who need a single tool capable of drilling, chamfering, and end milling in one operation. With a 1/4 inch cutting diameter, a 60-degree point angle, and four flutes, this tool handles both plunge cutting and peripheral milling in ferrous and non-ferrous materials. The AlTiN coating adds heat resistance and extends tool life in demanding cutting environments. The 3/4 inch length of cut provides sufficient depth for most pocket and hole operations in this diameter class.

This drill mill is suited for CNC machining centers and manual mills in job shop, production, and tool room settings. Its 1/4 inch shank diameter fits standard collet chucks and end mill holders. The combination drill-mill geometry makes it particularly useful when a single setup must produce drilled holes and milled features without a tool change. Applications include spot drilling, chamfering, and light profiling in steel, stainless, cast iron, aluminum, and similar materials where AlTiN coating performance is appropriate.

Key Features

• Solid carbide construction provides rigidity and wear resistance in high-speed cutting
• AlTiN coating improves heat resistance and extends tool life in ferrous materials
• 60-degree point angle supports drilling, chamfering, and countersinking in one tool
• Four-flute geometry balances chip evacuation with surface finish quality
• 1/4 inch shank diameter fits standard collet and end mill holder tooling
• 2-1/2 inch overall length suits most standard tool holders without excessive overhang

Compatibility

Designed for use in CNC machining centers and manual milling machines equipped with standard 1/4 inch collet chucks or end mill holders. No specific machine model compatibility data was provided by the manufacturer for this SKU.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool holding and runout tolerances. Ensure the spindle is fully powered down and locked before loading or unloading the tool. Seat the shank fully into the collet or holder to the recommended grip length before tightening. Verify tool runout with a dial indicator before beginning a production run, as excessive runout will accelerate wear on a four-flute solid carbide tool.
