Harvey Tool 15406-C3 Drill Mill 4 Flute Solid Carbide Altin

Product Description

The HARVEY TOOL 15406-C3 is a solid carbide drill mill designed for combined drilling and milling operations in a single tool. With a 60-degree point angle, it transitions cleanly from plunge cutting to peripheral milling without a tool change. The 0.0937-inch mill diameter and 4-flute geometry deliver precise material removal in tight spaces. An AlTiN coating improves heat resistance and extends tool life in ferrous and high-temp alloy applications. Machinists and toolroom operators running CNC mills or machining centers are the primary users of this tool.

This drill mill suits applications where a single tool must drill, chamfer, and end mill in one setup. The 3/8-inch length of cut and 1/8-inch shank diameter make it appropriate for small-bore work and fine-detail profiling in die work, mold making, prototype machining, and precision part manufacturing. The 60-degree point angle also makes it suitable for spotting, countersinking, and chamfering operations on a variety of workpiece materials including steel, stainless, titanium, and hardened alloys where AlTiN coatings perform well.

Key Features

• Solid carbide construction provides rigidity and wear resistance in demanding cutting conditions
• AlTiN coating delivers elevated heat resistance for dry or high-speed machining of ferrous and hard alloys
• 60-degree point angle enables spotting, chamfering, and plunge entry in a single tool
• 4-flute design balances chip evacuation with surface finish quality
• 0.0937-inch mill diameter suited for fine-detail and small-bore machining work
• 1/8-inch shank diameter compatible with standard collet toolholding systems

Compatibility

Designed as a direct-fit replacement for 1/8-inch shank drill mill toolholders and collet chucks used in CNC machining centers and manual knee mills performing combined drilling and milling operations.

Installation Notes

Installation is performed by a machinist or toolroom operator. Secure the 1/8-inch shank in a matching collet or end mill holder torqued to the toolholder manufacturer specification before spindle engagement. Verify runout at the tool tip with a dial indicator before beginning cuts, as excessive runout accelerates wear and degrades hole quality on a tool of this diameter. Power down and lock out the spindle before any tool change or collet adjustment.
