Hot Ball Insulation cutter

To make a 40 mm diameter channel on insulating materials behind
plasterboard without damaging them.
PERFECT to make your multimedia connections, switch and socket
installations invisible.
TIME-SAVING = no need to groove the wall and to repaint it.
STEP 1 : drill two 40 mm diameter holes on the plasterboard, in vertical way
to each other with maximum 2,50 m width.
STEP 2 : uniformly heat the hot ball surface with a welding torch during 3
minutes.
STEP 3 : insert the hot ball into the hole above. The hot ball melts the
polystyrene to make a channel connecting the 2 holes.
