This tool is ideal for the removal of dirties which may be left over the inside wall of casing, such as solid cement, hard wax, various salt crystals or deposits, perforation burrs, iron oxide residues resulted from rusting, so as to make all downhole tools pass through casing unblocked. Especially when a small circular clearance is available between the down-hole tools and casing inside diameter, the complete scrapping operation becomes more necessary before further working.
