The HDM-100 hole-drilling module may be installed on the end of all Smart-binder SB-2, SB-3 & SLB systems in order to drill a number of holes into each booklet.
The advantage of the HDM-100 over the optional hole punching module CHP-101 is that the HDM-100 can insert holes in booklets up to the Smart-binder maximum of 10mm thickness.
