Tool labels do NOT show the special tools on a 1 : 1 scale, but only as three-dimensional sketch of uniform size. Together with the data on tool number, tool group, and tool class, the self-adhesive pvc-labels are a good identification-aid for any tools. They fulfill further classification functions only to a limited extent. The labels are self-adhesive. Alternatively, the tool labes may be glued on a magnetic-foil carrier of the same size.
