The drilling machine is used for drilling holes in exterior roller blinds’ guides. This is a semi-
automatic device with a programmable bumper, i. e. the operator enters the profile length and
the number of holes and the drill program determines the intervals at which they are to be
found. The operator operates the drill levers and picks up drilled profiles. The bumper moves
the strip to the next hole position. The bumper returns to its initial position after work has
finished.
