The image on the cover of Security Power Tools is a rotary hammer. This tool, also known as a hammer drill, is used for drilling into stone or concrete. It employs a rotating hammering motion that allows it to dig holes into the stone quickly with minimal effort. It can also work at low speeds for chiseling work and for restrained, more precise cutting.
