Most drill bits out there designed for tougher materials have some design feature that is made to dissipate heat. While titanium drill bits wear more slowly, you can sharpen cobalt drill bits again and again. For example, you’ll want to use a titanium carbonitride bit for harder materials, but you’ll be fine using titanium nitride for wood or plastic. Better heat resistance and durability than high speed steel bits. Basic Woodworking Tools – Essential Tools for the Budding Woodworker, Your email address will not be published. Can be used in both hand and drill presses. You’ll definitely get your money’s worth over time. Cobalt and titanium drill bits are both expensive.

Compared to cobalt drill bits, titanium bits have a much shorter lifespan for this very reason. If you’ll use them regularly for hard materials, then I’d recommend a good set of cobalt drill bits. As mentioned, the main advantage of cobalt bits over something like HSS (high speed steel) is the improved heat resistance. They’re most commonly used to cut through hardened materials that steel alone would struggle with. Cobalt drill bits can be sharpened many times over and far outlast a titanium coated drill. This drill bit is made out of an alloy of titanium nitride and high-speed steel. However, their small differences is what makes each of them a significant impact of different projects. While titanium is a pretty hard material, titanium drill bits are only coated with a thin layer of titanium nitride, which erodes quickly. However, the melting point isn’t as high as cobalt, so they’re often not as durable. Out of the three, cobalt drill bits are the hardest. The Main Differences Titanium Drill Bits vs Cobalt Drill Bits The Main Differences Titanium Drill Bits vs Cobalt Drill Bits are: Titanium Drill Bits are made of steel and coated with either titanium nitride or titanium carbonitride, whereas the Cobalt Drill Bits are made from a mixture of cobalt and steel alloy.
