Abstract: A pipe cutter according to the invention has an inner head part which, in the working position, rotates about a pipe which is clamped in the inner head part and is to be processed. Integrated in the inner head part are a spring-mounted cutting wheel head (8) having a cutting wheel (7) for cutting the pipe and a plurality of support rollers (9) in spring-mounted receptacles (10). The arrangement and formation of cutting wheel (7) and support rollers (9) is such that the clamped pipe is at right angles to the cutting wheel (7), and a right-angled cut is thus achieved. Moreover, a defined feed cutting force can be set by the spring mounting of cutting wheel head (8) and support roller receptacles. During cutting, the pressure on the pipe decreases with increasing cutting depth, and the pipe can thus be cut cleanly and without burrs.

Abstract: A pressing tool for tightly pressing sleeve-like fittings (32a) includes a hydraulic cylinder device having a fork-like connecting part (7) and a drive motor. A pressing jaw (51) with a fastening pin (50) is fastened in the fork-like connecting part (7). A piston of the hydraulic cylinder device, which piston is connected to a piston rod (6), is moved out of the starting position in the cylinder by the drive motor. As a result, the piston rod (6) is extended from the cylinder. As a result of the movement of the piston rod (6), the cheek plates (51a, 51b) of the pressing jaw (51) are moved apart in the region of actuation surfaces (8a, 8b) of the cheek plates (51a, 51b) in order to press the cheek plates (51a, 51b) together in the region of the fittings (32a) to be pressed.
