Abstract: Cutting nippers (1), which are used for cutting tiles and glass, are provided with two long operating handles (5), two short pressure levers (6) and nipping tools located on the working ends of the pressure levers (6). To allow a simple and optimum design of the nipping tools, the nipping tools consist of cutting wheels (7, 8), preferably made of sintered metal carbide, which can be secured to the working ends of the pressure levers (6). The cutting wheels (7, 8) are secured with the aid of screws (11) and can be set to any desired rotational positions relative to the working ends of the pressure levers (6).

Abstract: An integral manipulator, in particular for glass panes, plates or metal sheets possesses a centrically arranged grip and may be attached by means of a suction dish to planar or slightly curved smooth surfaces. At the suction dish of the integral manipulator consisting of rubber-resilient material between the suction edge and the grip there is arranged a circumferential gripping edge.

Abstract: A glass cutter includes a head at one end, a manipulator at the opposite end, a casing arranged at the head and defined by a support plate and a circular cover plate firmly connected thereto, a plurality of cutting discs supported circularly and rotatably between the support plate and the circular cover plate, of which cutting discs always one is in readiness for cutting. The casing of the cutting discs is retained exchangeable in an elongated recess at the head of the glass cutter and the support plate is formed multi-edged at the perimeter. The support plate of the cutting discs engages with two flattened faces parallel to one another at lateral confinements of the recess which defines an arc at its inner end at the head of the glass cutter. Two opposing grooves parallel to the lateral confinements of the recess are associated with the recess in advance thereof for accommodating the portions of the stand-by cutting discs projecting relative to the casing of the cutting discs.
