Abü.-.- hen from the fact that such a clamping ao The extensions of the flanks of the pincer teeth mechanism is only suitable for pipes, the material cut preferably at an angle soft enough to deform, is by about 60 ° . Furthermore, the teeth of the jaws are appropriately damaged by this clamping mechanism, the pipe surface is considerably damaged at a distance of at least 3.175 mm, which means that the operating time is arranged far from one another,
special thin-walled pipes are considerably shortened »5 For assembly reasons, the. If the pipe material is hardened, as pipe wrench ring bushings are provided, which from hammer drill rods are usually of the Fa ¹ I, removable with the upper and lower gripping arrangement, this clamping mechanism is not applicable because connected and at the upper or lower end of the teeth a hole is not made deep enough in the material.
