Micro 100 DM-125-290X Drill Mill 1/8 in 2 Flute Solid Carbide

Product Description

The MICRO 100 DM-125-290X is a solid carbide drill mill designed for operations that require both drilling and milling in a single tool. With a 1/8 inch diameter and a 90-degree point angle, it can plunge into a workpiece and then move laterally to mill a feature without a tool change. The AlTiN coating provides thermal resistance and hardness, extending tool life in demanding cutting conditions. This drill mill is intended for use by machinists and toolmakers working on CNC mills and machining centers where multi-function tooling reduces cycle time and setup complexity.

This tool fits applications in precision machining environments where small-diameter combined drilling and milling operations are required. The 1/8 inch shank diameter makes it compatible with standard collet systems. Its 1/2 inch length of cut accommodates moderate-depth features in ferrous and non-ferrous metals, hardened steels, and similar materials where AlTiN coatings perform well. Typical users include job shop machinists, tool and die makers, and production CNC operators working with tight-tolerance parts.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating for elevated heat resistance and extended tool life
• 90-degree point angle enables accurate plunge entry and lateral milling
• 2-flute geometry provides efficient chip evacuation in drilling and milling operations
• Matched shank and cutting diameter at 1/8 inch simplifies collet selection

Compatibility

Designed as an OEM-style replacement or direct-use drill mill for CNC machining centers and manual mills equipped with standard 1/8 inch collet or chuck systems.

Installation Notes

Installation is performed by qualified machinists using appropriate collet toolholders rated for the 1/8 inch shank diameter. Ensure the machine spindle is fully stopped and the control is in a safe state before loading or unloading the tool. Verify runout with a dial indicator after seating the tool to prevent premature tool failure. Follow shop-standard speeds and feeds for the workpiece material and coating type.
