The installation has tool holders (3-5) permitting simultaneous fixation of two saw blades (6), on a vertical axis of a jig-saw. A suction branch sucks sawdust and dust, and a blower evacuates the dust. The blades are positioned at cutting depth obtained by adjusting height of a sole plate by its holder (11) that is maintained by clamping a bolt axle (14) that moves in orifices of a holder (10) fixed on chassis of the jig-saw by screws.
