Question: 1 / 400

Which of the following types of drills can be used to drill holes in concrete?

Rotary hammer drills, electric drills, and hand drills

Rotary hammer drills, rock drills, and core drills

The correct answer highlights the appropriate types of drills that are specifically designed for drilling into concrete. Rotary hammer drills are powerful tools that utilize a hammering action combined with rotation, making them highly effective for breaking through the hard surface of concrete. Rock drills are also suitable as they are designed for heavy-duty applications, including drilling in rock and concrete. Core drills, which often use a hollow bit to cut out cylindrical sections of material, are ideal for creating larger holes in concrete without producing a lot of debris.

This choice provides a comprehensive understanding of the equipment best suited for concrete drilling, recognizing the unique functions each drill type serves in effectively handling the durability of concrete materials. The other options include drills that may not be suitable for this specific task, leading to less effective results when working with concrete.
