Stand-alone system designed to drill gas-filling holes into spacer frames which are not yet filled with desiccant. The frames are positioned manually. The double spindle drills the gas-filling holes from the outside into both sides of the profile. The hole on the visible side, which is about 0.5 mm smaller than the other, facilitates the insertion of the plastic plugs, which prevent the desiccant from entering the space between the glass sheets.
