Harvey Tool 988104 Drill Mill 1/16 in 4 Flute Solid Carbide

Product Description

The HARVEY TOOL 988104 is a solid carbide drill mill designed for combined drilling and milling operations in a single tool. With a 1/16 inch cutting diameter and a 120-degree point angle, it handles center drilling, spotting, and peripheral milling without a tool change. The 4-flute geometry supports efficient chip evacuation and surface finish in both plunge and side-cutting applications. The bright uncoated finish makes it well suited for non-ferrous metals and plastics where coating adhesion or heat buildup is a concern. Machinists and CNC operators working in tight-tolerance, small-feature applications will find this tool appropriate for production and prototype work alike.

This drill mill is intended for use in CNC machining centers, vertical mills, and high-speed spindle setups where small-diameter precision is required. Its 3/16 inch length of cut and 1/8 inch shank diameter make it a practical choice for shallow pockets, counterbores, chamfers, and spot-drilling tasks in small-scale workpieces. It is commonly used in shops running aluminum, brass, copper, plastics, and other non-ferrous materials where an uncoated carbide tool performs reliably.

Key Features

• 1/16 inch (0.0625 inch) cutting diameter for fine, small-feature work
• 120-degree point angle supports accurate spotting and center drilling
• 4-flute design provides clean surface finishes in milling passes
• Solid carbide construction offers rigidity and wear resistance in hard materials
• Bright uncoated finish is well suited for non-ferrous metals and plastics
• 1/8 inch shank diameter fits standard collets and tool holders on most CNC platforms

Compatibility

Designed as an OEM-style replacement or direct-use drill mill for CNC machining centers and vertical mills equipped with 1/8 inch collets or tool holders accepting a 1/8 inch shank diameter.

Installation Notes

This tool should be installed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe state before inserting or removing the tool from the collet or tool holder. Verify runout at the collet before running at speed, as small-diameter carbide tools are sensitive to lateral deflection. Follow the machine manufacturer and tooling manufacturer guidelines for feed rate and spindle speed appropriate to the workpiece material.
