摘要:A casing cutting tool, to be disposed downhole in a casing string on a drillstring,for the cutting and/or milling of casing strings. The tool has a main body with a pluralityof rotatable blades which can rotate between a first retracted position to a secondposition substantially at right angles to the main body. In this second position, cuttingsurfaces on the blades engage the casing wall, and rotation of the tool results in cuttingof the casing. A plurality of stabilizing arms are rotatably attached to the main body. Alink between the blades and the stabilizing arms forces the stabilizing arms to rotateoutward when the blades rotate outward. The stabilizing arms are dimensioned to spanthe inner diameter of the casing string, while leaving clearance to rotate the tool. Theoutermost ends of the stabilizing arms are rounded to avoid cutting the casing andreduce drag.
