A tool and method for deburring the edge of a hole through a plate, pipe, duct, or similar workpiece. The edge to be deburred is the edge away from the operator of the tool, e.g., the edge on the far side of the plate or on the inside of the pipe or duct. The tool has a pivotal deburring blade at the distal end of a longitudinal member. The blade is pivoted substantially parallel to the longitudinal member for insertion of the tool through or withdrawal of the tool from the hole. The blade is pivoted substantially perpendicular to the longitudinal member for deburring the edge of the hole. Pivoting of the blade is controlled without direct manipulation of the blade by the operator and without the use of any other members.
