What is the main purpose of a power drill with a bit?

Reviewed by Jordan Morley, Editorial Lead at 247SimpleTests. Written by the 247SimpleTests Editorial Team from the official source material cited on every question.

Correct answer

To bore holes (and, with a driver bit, to drive screws)

  1. A To bore holes (and, with a driver bit, to drive screws)
  2. B To smooth surfaces
  3. C To measure distance
  4. D To make straight cuts

Why this is the answer

A power drill spins a bit to bore holes in wood, metal, plastic, or masonry, depending on the bit used. With a screwdriver (driver) bit, many drills can also drive and remove screws, and a drill/driver or impact driver is commonly used for fastening. Selecting the correct bit type and size for the material is important, as is securing the workpiece and using steady pressure. The drill's core job — boring holes, and optionally driving fasteners — distinguishes it from saws (cutting) and sanders (smoothing). This is basic power-tool knowledge.
