A bi-directional handheld planer is used to remove chips from a workpiece in order to make the surface planar. The handheld planer allows the user to choose between a pair of opposing exhaust ports from which the chips are to be expelled from the planer. Particular handheld planers have a normal direction of air flow that is transverse to the longitudinal direction of the planer. The bi-directional handheld planer provides for exhaustion of the chips through either of a pair of exhaust ports, and an insert can be disposed within the cutting chamber to pre-direct the chips toward one of the exhaust ports in order to prevent the clogging of the exhaust port which caused by the turbulence and constant contact of the chips being re-directed in the direction opposite the normal flow of air through the housing of the planer.
