A jamb saw is a special-purpose electric power saw that is designed to make undercuts around door jambs (casing at the bottom of the door). You will do these undercuts to slide in the laminate or wooden flooring below the door casing which will give it a clean appearance. Hence, they are also called undercut saws.

A jamb saw or an undercut saw is essentially a circular saw with its blade mounted on an arbor that is perpendicular to the body of the tool.
