Final answer:
The statement is true; a hammer drill is designed for effective drilling into hard surfaces such as brick and concrete, utilizing a percussive action to break the material apart while rotating the drill bit.
Explanation:
A hammer drill can and usually should be used for drilling into a hard surface like brick or concrete, i.e., masonry. The answer to this statement is true.
Hammer drills are equipped with a percussive action mechanism that allows them to drill into these tough materials effectively. As a drill bit rotates, the hammer drill also punches in and out rapidly, breaking up the material with each impact. This action resembles the combination of a mini jackhammer and a standard drill.
For instance, when a person strikes a hammer against a hard surface for crushing, the force exerted helps break apart the material, much like a hammer drill does on a smaller, but more targeted scale. If the objective is to control fragmentation, such as using a makeshift cardboard shield, this technique is similar to how a hammer drill is used in a controlled manner for precise drilling into masonry without causing excessive damage to surrounding areas.
In comparison, using a standard drill without the percussive action on masonry might result in a slower process, potentially damaging the drill bit or the drill itself. This illustrates the efficiency and necessity of using the proper type of drill for specific materials.
