PICCOLINO external roller burnishing tools are a particularly compact design for use on machines with limited working space, such as multi-spindle and Swiss-type lathes or rotary transfer machines.

When setting the tool diameter above the  nominal size of the tool then the taper will overlap the cage. Therefore the dimension “X” (see overleaf) will increase. This increase will be about 0.2 mm per 0.01 mm diameter en-largement ( = one mark on the tool scale) of the tool setting.
