Improvements in the construction of mechanical drills for wood, of the type of which the chuck shaft, subject to the usual movement rotating on its own axis, can also be left at the will of the operator subjected to a simultaneous rectilinear oscillating movement of the aforementioned rotator, the oscillation being of variable magnitude, characterized in that the two movements of the drill, the rotary and the oscillatory come from the same engine through transmission belts that drive two axes, one of which is the drill shaft itself and another axis that sets in motion a device, of connecting rod that prints reciprocating rectilinear movement to the said drill-holder shaft, mounted on slide.
