<p>Said improvements can be used for cutters provided with a base to support th e ceramic piece that is to be cut, longitudinal guides for displaceable assemb ly of a support on which a collapsible cutting wheel holder is mounted, said holder being provided with a threaded hole for mounting an actuating lever that makes it possible to press and displace the cutting wheel on the cerami c 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 a ny given geometry with the purpose of reducing the frequency of vibration there of during grating of the ceramic pieces, and at least one longitudinal plane th at 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.</p> |
