Harvey Tool 15304 Drill Mill 1/16 in 4 Flute Solid Carbide

Product Description

The HARVEY TOOL 15304 is a solid carbide drill mill designed for combination drilling and milling operations in a single tool. With a 1/16 inch cutting diameter and a 90-degree point angle, it handles center drilling, spot drilling, chamfering, and end milling without a tool change. The 4-flute geometry provides rigidity and a clean finish in ferrous and non-ferrous materials. The bright uncoated finish suits applications where coating buildup could affect tolerances at this small diameter. Machinists and tool-and-die professionals use this tool in CNC machining centers and manual mills where small-diameter multi-function capability is required.

This drill mill is suited for precision work in tight spaces, small-part machining, and mold-and-die applications where a 1/16 inch diameter is required. The 3/16 inch length of cut accommodates shallow pockets and through-features in thin-wall workpieces. The 1/8 inch shank diameter fits standard collets and tool holders commonly found in vertical machining centers and high-speed spindle setups. It is appropriate for use in aluminum, brass, plastics, and light steels where fine detail and positional accuracy are priorities.

Key Features

• 1/16 inch (0.0625 inch) cutting diameter for fine, small-diameter work
• 90-degree point angle enables spot drilling, chamfering, and countersinking in a single pass
• 4-flute design provides increased core strength and improved surface finish
• Solid carbide construction delivers rigidity and wear resistance at small diameters
• Bright uncoated finish maintains dimensional accuracy where coating thickness is a concern
• 3/16 inch length of cut with 1-1/2 inch overall length for reach in shallow features

Compatibility

Designed for use in CNC machining centers and manual milling machines equipped with collet systems or tool holders accepting a 1/8 inch shank diameter.

Installation Notes

Installation and use of this tool should be performed by qualified machinists familiar with small-diameter tooling practices. Ensure the spindle is fully stopped and the machine is powered down before loading or unloading the tool from its holder. Use a collet sized to the 1/8 inch shank and verify runout before cutting, as small-diameter carbide tools are sensitive to misalignment. Follow the machine manufacturer and tooling manufacturer guidelines for speed, feed, and depth-of-cut parameters appropriate to the workpiece material.
