摘要： The invention relates to a downhole tool (10) for use in a casing or tubing (99) in a well comprising a support (15) and a brush (12). The downhole tool (10) further comprises a lever arm (13) having a first end (13-1) and a second end (13-2) opposite the first end (13-1). The lever arm (13) is pivotably mounted to the support (15) and the brush (12) is mounted at the second end (13-2) of the lever arm (13). A driver means is provided for driving the lever arm (13) outwardly to press the brush against a wall of the casing or tubing (99) in operational use of the downhole tool (10). An advantage of the invention is that one size of the downhole tool may fit all sizes of a casing or tubing. The invention also relates to method of cleaning and honing casings or tubings in a well.
