Notice the Infeed and outfeed table heights relative to the high speed rotating cutting blades. A jointer or in some configurations, a jointer-planer (also known in the UK and Australia as a planer or surface planer, and sometimes also as a buzzer or flat top) is a woodworking machine used to produce a flat surface along a board's length. As a jointer, the machine operates on the narrow edge of boards, preparing them for use as butt joint or gluing into panels. A planer-jointer setup has the width that enables smoothing ''('surface planing')'' and leveling the faces (widths) of boards small enough to fit the tables.
== Name == The jointer derives its name from its primary function of producing flat edges on boards prior to joining them edge-to-edge to produce wider boards. The use of this term probably arises from the name of a type of hand plane, the jointer plane, which is also used primarily for this purpose.
