A rotary drill makes light work out of punching holes through hard surfaces such as concrete and brick. Also referred to as a percussion drill, the rotary drill uses a piston mechanism instead of the clutch used on the similar hammer drill. The end result is a more powerful blow, which shortens drilling time and creates beautifully accurate holes. For extra comfort and grip, look for products that feature an ergonomic, soft-grip handle. And for quick bit changes, choose a rotary drill with a keyless chuck.
