DISPOSITIF D'AIDE AU PERÇAGE D'UNE PLANCHE
A device assists in drilling a board with a tool having a drill bit, means for rotatably driving the bit, and a guide member—having an outer face with a generally cylindrical shape of revolution about the bit's rotation axis—for guiding the bit in rotation and movement along the bit's longitudinal axis. The device has a rigid body with a flat sole (contact surface). Guide space(s) pass through the rigid body and open onto the sole. Each guide space is delimited laterally toward the outside by a cylindrical internal surface of revolution about a revolution axis orthogonal to the sole's main plane. The internal surface may interact with the guide member and guide the bit in rotation and longitudinal movement along the revolution axis. The internal surface has a radial expansion for stopping, in abutment therewith, the guide member during longitudinal movement of the tool toward the board.
