Exposed Blad Tube Deburring Tool

A cutting tool having a fluted, stepped body on one end and a straight shank, usually round with a squared drive, on the other end. In operation, the smaller portion of the body is inserted in the tube, until the blades contact the edges of the tube, and rotated with a t-handle tap wrench, or the like to remove the burrs from the inside and outside edges.
