It's a device that cuts grooves into wood using cutting bits that come in a variety of different profiles. It's good for making slots (e.g. mortises for mortise-and-tenon construction) as well as decorative details, such as chamfers, roundovers, and ogee profiles. You can also use a pattern bit to copy a cut-out shape with it.
