<p>Said improvements can be used for cutters provided with a base to support the ceramic piece that is to be cut, longitudinal guides for displaceable assembly of a support on which a collapsible cutting wheel holder is mounted, said holder being provided with a threaded hole hole for mounting an actuating lever that makes it possible to press and displace the cutting wheel on the ceramic piece by marking the breaking or cutting line thereof. The periphery of the handle of the cutting wheel has at least three longitudinal grooves having any given geometry with the purpose of reducing the frequency of vibration thereof during grating of the ceramic pieces, and at least one longitudinal plane that is co-planar or projects inward relative to the general outer surface of the handle for actuating the end of the lever intended for the immobilization thereof in the cutting wheel holder. <IMAGE></p> |
