ABSTRACT:
A hand-held bending tool for conduits, tubes, rods, and the like is provided. The bending tool includes a bending matrix and a sliding shoe that during a bending process are movable relative to one another and each have a groove-like recess in which the tube that is to be bent is disposed. The recess of the bending matrix extends in a curved manner in conformity with the tube bending radius that is to be produced. The tool includes at least one support for the tube. The tube is embodied as an electric tool having a motor that rotatably drives the bending matrix via a reduction gear arrangement, with the flux of force during a bending process being self-contained.
