Downhole wireline cleaning tool

A downhole wireline cleaning tool adapted to scrape and remove objects, and thereby increase said inner diameter to an initial inner diameter of the casing, the casing having an internal cross-sectional area encircled by a wall of the casing and the tool having a centre tool axis and extending in a longitudinal direction, comprising:

• a tool housing having a first housing part and a second housing part,
• a projectable arm which is pivotably connected with the first housing part at a first end of the projectable arm, the projectable arm having a plurality of bits in a second end, said projectable arm being movable between a retracted position and a projected position in relation to the tool housing in order to bring the bits in contact with the object,
• an arm activation assembly for moving the projectable arm between the retracted position and the projected position, and
• a rotatable shaft arranged in the second housing part and rotatably connected with the first housing part for rotating the projectable arm,
• wherein the bits are arranged along an extension extending from the second end towards the first end of the projectable arm, which extension is curved in order to vary a distance from the tool housing to the bit in contact with the object upon rotation of the projectable arm, and wherein the extension of the arm extends across the centre tool axis in at least the retracted position, so that the bits of the arm are arranged to scrape the entire internal cross-sectional area of the casing when the arm is rotated.
