摘要

The invention relates to a toolholder guide system in manual ceramic cutters, comprising parallel guides (2) for the longitudinal movement of a tool holder (1) that comprises a handle (11) for the actuation thereof and carries a cutting tool (12) for scoring a ceramic part. The guides (2) are formed by a profile, preferably made of aluminium, each guide (2) comprising upper and lower steel rods (21, 22), disposed longitudinally, forming races for bearing carriages (3) disposed on the sides of the toolholder (1). Each bearing carriage (3) comprises two end bearings (31, 32) disposed at the same height and at least one intermediate bearing (33) disposed at a lower height than the two end bearings.
