Abstract
Apparatus for drilling tiles and the like, which is characterized, essentially, by comprising a support base for the elements to be drilled, perpendicular to which is mounted a sliding and rotating rod, carrier at its end closest to the element to be drilled a replaceable drilling tool whose shank is subject to the action of an elastic means that tends to keep the aforementioned drilling tool supported with the necessary pressure in the element to be drilled, and is also provided with a driving handle and an articulated lever which, overcoming the action of the cited elastic means, allows to act on the stem in the sense of lifting the tool separating it from the base.
