What is the primary function of a power drill?

The primary function of a power drill is to make holes. Power drills are specifically designed to drill through various materials such as wood, metal, and plastic. By using a rotating drill bit powered by an electric motor, these tools efficiently create holes of different diameters and depths, depending on the bit used. Making holes is essential in many construction and woodworking tasks, as it allows for mounting, fastening, and the assembly of materials.

While cutting, grinding, and polishing are important tasks in various trades, they are typically performed using different specialized tools. Therefore, making holes is the most accurate and direct function of a power drill.
