A planer comprising a body mounted on a shoe, the shoe having an aperture formed through it; a cutting drum rotatably mounted within a recess formed by a wall within the body, a part of the periphery of the cutting drum 6 projecting through the aperture in the shoe; a motor mounted within the body to rotatingly drive the cutting drum; at least one cutting blade mounted on the periphery of the drum capable of planing a work piece when the drum is rotating; an airflow generator which creates an air flow when the planer is in use within the body for use for entraining debris created by the cutting action of the blade to assist in the removal of the debris; directional means which directs the airflow within the body towards the area where the cutting blades cuts a work piece; wherein an expulsion aperture is formed in the wall of the recess forward of the cutting drum through which any debris created by the cutting action of the blade would be thrown by the rotating blade; and the airflow is directed within the body to a point below the expulsion aperture in the wall of the recess and is directed to be blown across the aperture within the body in a direction having an acute angle to the direction of travel of any debris in order to entrain the debris in the airflow within the body. <IMAGE> |
