When drilling into brick or concrete block, a hammer drill paired with a masonry bit is essential due to the hardness and density of these materials. A hammer drill functions by using a pulsing action that combines rotation with a hammering motion, which effectively breaks through tough surfaces like brick and concrete. This feature allows the drill bit to penetrate more efficiently compared to a standard drill, which lacks the impact mechanism necessary for such hard materials.

A masonry bit is specifically designed with a tungsten carbide tip that enhances its ability to cut through masonry. The unique design of these bits prevents premature wear and allows for more effective drilling.

In contrast, other tools mentioned, such as a regular drill or rotary tool, would not provide the necessary power or appropriate bit design for drilling into brick or concrete. Using inadequate tools could lead to inefficient drilling or damaging equipment.
