Harvey Tool 15308-C1 Drill Mill 0.125 in 4 Flute Solid Carbide

Product Description

The HARVEY TOOL 15308-C1 is a solid carbide drill mill designed to perform both drilling and milling operations in a single tool. With a 0.125 inch (1/8 inch) cutting diameter, a 90-degree point angle, and four flutes, it handles center drilling, chamfering, spotting, and light milling in one setup. The TiN (Titanium Nitride) coating extends tool life by reducing friction and increasing surface hardness. Overall length is 1.5 inches with a 0.5 inch length of cut. Machinists and tool-and-die professionals working on CNC machining centers and manual mills rely on this tool to reduce tool changes and maintain positional accuracy across multiple operations.

This drill mill is suited for use in light-duty machining applications on ferrous and non-ferrous materials where a combination drilling and end milling operation is required. The 0.125 inch shank diameter matches the cutting diameter, making it compatible with standard 1/8 inch collets and toolholders. Typical applications include spotting holes prior to drilling, countersinking, chamfering edges, and shallow milling passes in production and prototype machining environments.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding machining operations
• 90-degree point angle for accurate spotting, chamfering, and center drilling
• Four flutes provide smooth chip evacuation and improved surface finish during milling passes
• TiN coating reduces friction and extends tool life in ferrous and non-ferrous applications
• 0.5 inch length of cut allows milling and drilling at shallow-to-moderate depths
• Matched shank and cutting diameter (0.125 inches) simplifies collet selection and toolholder setup

Compatibility

Designed for use with standard 1/8 inch precision collets and toolholders on CNC machining centers and manual milling machines requiring combined drilling and milling capability.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine spindle fully stopped and energy isolated per OSHA lockout/tagout procedures. Ensure the collet and toolholder are clean and free of chips before seating the shank to the correct depth. Do not exceed the recommended depth of cut for the tool diameter, as solid carbide drill mills at this size are sensitive to side-load deflection. Verify runout at setup to maximize tool life and hole quality.
