ABSTRACT:
A deburring tool for reaming inner and outer diameter end portions of tube and pipe-like workpieces includes a cast housing having an integrally formed conical support member therein. The conical support member has a base portion disposed adjacent one end of the housing and an apex area spaced toward the other end of the housing. Radially disposed apertures having a predetermined width dimension divide the conical support member into a plurality of wedge portions. A blade assembly is comprised of a plurality of separate blades which are fixedly secured to each other in a pattern identical to the pattern of apertures in the support member. The blades have a thickness dimension which is greater than the width dimension of the apertures in order that the blade assembly will be retained in the conical support member by a press-fit relationship established between the blades and apertures. Each blade includes first and second cutting surfaces protruding axially from the support member and adapted for deburring engagement with the inner and/or outer diameter end portions of an associated workpiece.
