Harvey Tool 15310-C3 Drill Mill 4 Flute 90 Point Altin Carbide

Product Description

The HARVEY TOOL 15310-C3 is a solid carbide drill mill designed for combined drilling and milling operations in a single tool. With a 90-degree point angle and four flutes, it transitions cleanly between plunge cutting and peripheral milling without a tool change. The AlTiN (aluminum titanium nitride) coating adds surface hardness and heat resistance, extending tool life in ferrous and hard alloy materials. The 0.1562-inch mill diameter and 9/16-inch length of cut make it well suited for small-feature work requiring tight tolerances. Machinists and toolroom operators working on CNC machining centers and manual mills are the primary users of this tool.

This drill mill is intended for use in precision machining environments where a single tool must perform both spot drilling and end milling functions. It fits applications in aerospace, mold and die, and general metalworking where floor-to-floor time matters and tool changes add cost. The 3/16-inch shank diameter suits small-bore collet systems and compact tool holders common in high-speed machining setups. Its 2-inch overall length keeps deflection low in confined pockets and close-tolerance features.

Key Features

• 90-degree point angle enables spot drilling, chamfering, and plunge entry in one tool
• Four flutes provide efficient chip evacuation and a smooth finish on peripheral cuts
• AlTiN coating improves wear resistance and thermal stability in high-speed cuts
• Solid carbide construction maintains rigidity at small diameters where HSS tools deflect
• 0.1562-inch mill diameter with 9/16-inch length of cut for small-feature precision work
• 3/16-inch shank diameter compatible with standard ER collet and precision tool holder systems

Compatibility

Designed for use in CNC machining centers and manual mills equipped with collet systems accepting a 3/16-inch shank diameter. No specific machine model compatibility was provided by the manufacturer for this SKU.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's setup procedures. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before loading or removing the tool. Use a calibrated collet or precision tool holder to minimize runout, which is critical at this diameter. Do not exceed the recommended depth-of-cut for the work material; consult published carbide tooling feeds-and-speeds data for the specific alloy being machined.
