Carbide Drills for Titanium

Titanium is a difficult material to drill because heat builds quickly at the cutting edge and chip control must be carefully managed. That is why carbide drill selection has a direct impact on drilling stability, tool life, and hole quality.

This page introduces two carbide drill series for titanium applications, with a focus on features that support stable, efficient machining.

Why Carbide Drills Are Used for Titanium

Titanium drilling requires a tool that can handle concentrated heat, maintain edge performance, and support stable chip evacuation. Carbide drills are widely used for these conditions because they help improve drilling stability, hole quality, and tool life in demanding applications.

Lineup for Titanium Applications

For titanium drilling, the right drill depends on the machining priority, whether that is reducing burrs, improving hole accuracy, maintaining process stability, or supporting a wider range of applications. NACHI offers multiple carbide drill options designed to meet these needs in demanding drilling environments.

Aqua REVO Drill Series

Overview

The Aqua REVO Drill Series is designed to improve drilling performance with a carbide material that combines hardness and toughness. It also features improved wear and chipping resistance, a straight cutting edge that helps reduce cutting stress, and a REVO-D coating developed for drilling multiple materials.

These features make it a strong choice when stable performance and longer tool life matter in demanding drilling applications.

Challenges in Titanium Drilling

Heat Concentration at the Cutting Edge

Titanium has low thermal conductivity, which means heat tends to stay near the cutting edge during drilling. This can increase tool wear and make stable holemaking more difficult in demanding applications.

Chip Evacuation and Tool Wear Control

Titanium drilling also requires careful chip evacuation and edge protection to maintain hole quality and process stability. In these conditions, drill features related to coolant delivery, wear resistance, and chipping resistance can play an important role in overall performance.

Conclusion

Titanium drilling requires careful control of heat, chips, and tool stability. Choosing a carbide drill with the right design features can help improve drilling performance, hole quality, and process reliability.

NACHI’s Aqua Drill EX Flat Series and Aqua REVO Drill Series offer two carbide drill options for titanium applications, each designed to support stable and efficient machining in demanding environments.
