Product Information
Full details
The Dewalt Titanium Nitride Drill Bit Set is designed for professional contractors, woodworkers, and DIY enthusiasts who require precision and longevity for drilling into metal, wood, and plastics. Its primary benefit is the specialized speed tip design that minimizes bit walking, ensuring accurate hole placement every time. However, users should note that while the titanium coating significantly enhances durability, these bits are not intended for high-hardness hardened steel applications.

FAQs
Can these bits be used in a hammer drill?
These bits are designed for rotary drilling. Using them in hammer mode may damage the tips and reduce the life of the bit.
Are these bits resharpenable?
While the geometry can be ground, doing so will remove the titanium nitride coating, which reduces the bit's heat and wear resistance.
Can I use these for masonry or concrete?
No, this set is designed for metal, wood, and plastic. Masonry requires carbide-tipped bits specifically designed for stone and concrete.
What is the largest drill size included?
The 21-piece set contains a range of fractional sizes; please refer to the specific labeling on the internal case tray for the exact size capacity.
Do the bits rust if left out?
The titanium coating provides some protection, but they are not rust-proof. Always clean and return them to the case after use.
Are these bits compatible with standard hex-shank quick-change adapters?
This set features round shanks with flat surfaces; they are intended for use in standard keyed or keyless chucks rather than 1/4-inch hex quick-change adapters.
Troubleshooting
Bit wandering or slipping when starting a hole
Ensure the speed tip is making full contact with the surface and use a lower initial RPM to allow the tip to 'bite' the material.
Bit becomes extremely hot or smokes
Reduce your drilling speed and apply a cutting fluid or lubricant, which will help dissipate heat and extend the life of the titanium coating.
Bit spins inside the drill chuck
Verify that the bit is inserted deep enough into the chuck and that the chuck is tightened firmly against the non-spin shank section.
Pros and Cons
Pros
- Speed tip prevents wandering for precise hole starting
- Titanium coating provides excellent heat resistance
- No-spin shanks ensure consistent power transfer
- Durable case keeps bits organized and easily accessible
Cons
- Not suitable for drilling through hardened, tempered steel
- Requires careful storage to prevent moisture leading to oxidation over time
- Limited variety for extremely large diameter holes
Setup, Compatibility & Care
These drill bits are compatible with most standard corded and cordless drills equipped with a 3/8-inch or 1/2-inch chuck. To set up, ensure the bit is inserted fully into the chuck and tightened securely to utilize the no-spin shank feature. For care, wipe bits clean of metal shavings or wood debris after each use. Store them back in the provided case to prevent contact with other tools that could chip the titanium finish. If the bits become exposed to moisture, apply a light coat of machine oil before storage to prevent corrosion.
