Abstract:
1. A planer comprising: a shoe, the shoe defining an aperture; a body mounted on the shoe, the body including a wall and the wall defining a recess and an expulsion aperture; a cutting drum rotatably mounted within the recess, the drum having a periphery and a portion of the periphery of the cutting drum projects through the aperture in the shoe; a motor mounted within the body to rotatingly drive the cutting drum; a cutting blade mounted on the periphery of the drum and adapted for cutting a work piece when the drum is rotating, the cutting action of the blade causing debris created by the cutting to be ejected from the recess through the expulsion aperture; an airflow generator for producing an airflow within the body for entraining and removing debris created by the cutting action of the blade; a conduit defined within the body for directing the airflow, the conduit connected to the recess by the expulsion aperture, wherein the debris entering the conduit through the expulsion aperture travels substantially in a first direction, and the airflow through the conduit adjacent to the expulsion aperture travels substantially in a second direction, and the first direction of the debris and the second direction of the airflow intersect at an acute angle; and a deflector for guiding the airflow and entrained debris from within the body to outside of the body, the deflector having an exterior surface and insertable into the planer body for connection to the conduit, and wherein the conduit directs the airflow over the exterior surface of the deflector prior to directing the airflow to the vicinity of the expulsion aperture.
