ABSTRACT:
A hand-held power file has an abrasive belt trained around spaced apart drive and idler pulleys. The drive pulley is located in a chamber and mounted upon an armature shaft of an electric motor. Also mounted upon the armature shaft is a fan that, in use, creates an air flow through the chamber to remove dust debris from the belt. The abrasive belt extends through an opening at the front of the tool's housing and which also serves as an inlet for the air flow. A bag, for receiving dust entrained in the air flow, is supported by outer and inner supports and fits over an outlet nozzle extending from the chamber.
