There are four main types of carbide drill bits: tungsten carbide, cobalt carbide, titanium carbide, and ceramic carbide.
Carbide drill bits are made from a combination of tungsten carbide and cobalt.
They are extremely hard, durable and long lasting, making them ideal for drilling through hard materials such as metal, stone, ceramic and fiberglass. They are also more resistant to heat and wear than other types of drill bits, making them ideal for repetitive drilling tasks.
Additionally, carbide drill bits can be used in wet or dry conditions, and they can be re-sharpened for extended life.
