Abstract
A downhole tool for cleaning debris from an inner surface of a downhole casing that includes an inner mandrel moveable within the casing; and a scraper mandrel movably coupled to the outside of the inner mandrel by the engagement of a lug within a groove, the scraper mandrel including a scraper blade positioned on an outside of the scraper mandrel. Longitudinal movement of the scraper mandrel relative to the inner mandrel causes the lug to move within the groove, causing the scraper mandrel and the scraper blade to rotate relative to the inner mandrel and clean debris from the inner surface of the casing. The longitudinal movement is achieved by restraining movement of the scraper mandrel relative to the inner mandrel by contacting the debris with a scraper blade on the outside of the scraper mandrel, causing the scraper mandrel to move longitudinally relative to the inner mandrel.
