DEVICE FOR GUIDING DRILL BITS FOR DRILLING HOLES

摘要

Consisting of a body (1) provided with two parallel walls (3 and 4) and with a plurality of parallel holes (5) of different diameters for the insertion of different diameters of drill bit, it is characterized in that inside the body (1) there is a void (14) that interrupts the holes (5) in the body (1) for collecting the dust waste produced when the hole is drilled. It comprises a rotary cover (9) that closes off the wall (3) and that includes a hole (10) of a diameter identical to the largest diameter of the holes (5) in the body (1) for preventing the dust from being able to exit via the holes (5) in the wall (3).
