Abstract
Perforated multiple drill characterized in that it is constituted basically by a main body, in which drill heads of different drilling sections are formed in descending order and staggered, and a fixing zone for its connection with the drilling machine; the drill heads being provided with recesses and projections that serve as a relation between the different steps of the main body in which the drill heads are housed; so that due to the different sizes of the drill heads and once the main body is connected to the drilling machine through its fixing area, the drilling of the drill holes can be drilled by just making the work make the right drill head which will start its work by highlighting it practiced and aided by its step recess, which will give once they are completely inserted in the hole, the desired size can be increased with the only used, which will start its work to reach the depth of drill in which its projection can take action, thus beginning again the previous process.
