The torque tool comprises a torque converter which includes: - at least three planet carriers; - at least three planetary gears encased in the three planet carriers; and each of the three planetary gears includes a sun gear and at least three planet pinions. Each of the three planet carriers has an input disc-shaped plate, directed towards an input shaft and an output disc-shaped plate directed towards an output shaft, both input and output shafts forming the main shafts of the torque tool. Two of the at least three planet carriers which are next to the input shaft have their output disc-shaped plates extending into sun gears with which they form a unitary centrally disposed in a first sun gear adjacent said input shaft and extending through sliding bearings located in following sun gears, a first large diameter of said stepped pin is commensurate with an interior diameter of said needle bearing and a second small diameter of said stepped pin is commensurate with interior equal diameters of said following sun gears. The planet pinion s of one of the at least three planet gears, which is adjacent to output gear, is each provided with a multiplicity of roll needles closely spaced together, said multiplicity of roll needles being inserted between each of said at least three planet gears anda n axle for supporting.
