ABSTRACT:
A ceramic cutting device having a base, longitudinal guides mounted to the base, and a support movably mounted on the longitudinal guides. A cutting-wheel handle holder is pivotably mounted to the support. A cutting-wheel handle is mounted to the handle holder and the cutting wheel is mounted to the handle. An actuating lever is mounted in a threaded hole in the handle holder so as to immobilize the handle so that the handle can apply pressure on a ceramic piece to be cut via the cutting wheel. The cutting wheel handle has an outer periphery with at least three longitudinally extended rebates which have a geometry that reduces the frequency of vibration during scoring of the ceramic piece by the cutting-wheel. The handle further has at least one longitudinally extending planar surface for engaging with the actuating lever.
