ABSTRACT:
A well bore cleaning tool comprises a plurality of collars which slip onto a pipe casing without welding, and can be securedly attached thereto using any conventional securing means, such as set screws. The collars are interconnected with a cable, disposed longitudinally on one side of the casing, substantially in a straight line. The well bore cleaning tool has utility in bore holes wherein there is a limited clearance or amount of space in the annulus (that is, the region between the exterior of the casing and the wall of the bore hole).
