What is the function of a masonry bit?

Masonry bits are specifically designed for drilling into tough materials such as concrete, brick, and block. They have a unique tip, often made from carbide or a similar hard material, which allows them to withstand the considerable resistance encountered when drilling into these hard substances. The fluted design of masonry bits enables the effective removal of debris while boring holes, ensuring that the bit can penetrate efficiently without getting stuck.

The other options do not accurately reflect the purpose and design of a masonry bit. For instance, driving screws into masonry would require a different type of tool, such as a masonry screw or an anchor, rather than a drill bit. Similarly, cutting through metal demands a completely different type of bit, such as a high-speed steel (HSS) drill bit, which is engineered for that specific material. Creating joints in brick typically involves the use of trowels or other hand tools rather than a masonry bit, which is focused solely on drilling.
