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.

The cover image is a photograph taken by Frank Deras. The cover font is Adobe ITC Garamond. The text font is Linotype Birka; the heading font is Adobe Helvetica Neue Condensed; and the code font is LucasFont’s TheSans Mono Condensed.
