Many different materials are used for or on drill bits, depending on the required application.
Tungsten carbide and other carbides are extremely hard materials that can drill in virtually all materials while holding an edge longer than other bits. Due to their brittleness and high cost they are mainly used for drill bit tips, small pieces of hard material fixed or brazed onto the tip of a bit made of less hard metal.
Titanium nitride (TiN) is a very hard ceramic material, and when used to coat a high-speed steel bit (usually twist bits), can extend the cutting life by three or more times. A titanium nitride bit cannot be properly sharpened, as the new edge will not have the coating, and will not have any of the benefits the coating provided.
Titanium aluminum nitride (TiAlN) is another coating frequently used. It is considered superior to TiN and can extend tool life five or more times.
Titanium carbon nitride (TiCN) is another coating and is also superior to TiN.
Our company has drill probably in all material and all sizes which can benefit customer with the right kind of guidance and accurate size.
