Which is the recommended drill bit type for drilling titanium effectively?

Carbide drill bits are recommended for drilling titanium effectively due to their superior hardness and wear resistance compared to other materials. Titanium is a tough, heat-resistant metal that can cause significant wear on tools; therefore, the hardness of carbide makes it an ideal choice as it can withstand the high temperatures generated during the drilling process without losing its cutting edge.

Additionally, carbide tools maintain their cutting performance for a longer duration, which is crucial in maintaining efficiency and precision when working with titanium. They can also be manufactured with various geometries and coatings that can further enhance performance when drilling this type of metal.

While cobalt drill bits are also a viable option and possess good hardness, they do not offer the same level of performance or durability in comparison to carbide when specifically drilling titanium. High-speed steel bits are not as effective for titanium because they tend to dull quickly under the stresses of drilling this challenging material. Diamond bits, while extremely hard and effective for cutting harder materials, are not typically used for metal because they lack the necessary toughness and can be prohibitively expensive for such applications.
