A drill bit is a cutting tool used to create round holes. Most drill bits are used to cut through wood, steel and other metals. A masonry drill bit is made to cut through concrete, brick and stone. Masonry drill bits are typically made with a tungsten carbide tip to ensure it is strong enough to penetrate and drill through brick and stone.
