- Material: Cobalt drill bits are made of a mixture of cobalt and steel alloy. They are usually 5% to 8% cobalt, with the rest being steel. This makes them durable and able to drill through rigid materials like cast iron.
- Construction: Cobalt bits are made with a steel alloy that contains a small amount of cobalt. This means they can drill into steel and harder metals, including cast iron. Titanium bits are made of steel, with a layer of titanium. They are not as strong as cobalt bits, and the coating wears down with regular use.
