ABSTRACT:
The pipe cleaner attachment includes a housing, a shuttle, and a shuttle guide. The housing has a closed end, an open end, a key and two brush levers and brush pad guide slots. The shuttle guide is a rod clamped in a bore through the closed end of the housing. The end of the rod outside the housing is clamped in a drill chuck for use. The shuttle is slideably mounted in the housing on the shuttle guide and engages the housing key, A pair of brush levers are pivotally mounted in the brush guide slots. A brush pad is attached to an end of each brush lever. Burnishing grooves are provided in the shuttle for burnishing the open ends of pipes with two different diameters. Upon insertion of a pipe into the housing, the pipe end is reamed, the burnishing grooves burnish the pipe end, the shuttle is moved toward the closed end and the brush pads clean the outside surfaces of the pipe.
