Abstract
Useful for drilling and countersinking, characterized in that it comprises a drill of conventional type and variable gauge on which a concentric body slides axially, whose pointed end or end, in the same sense as that of the support bit, is carved according to a machining of drill or flare; said piece is provided with a radial screw that allows to optionally fix its position on the bit; so that when this produces the corresponding hole, on contacting the work tip of the moving part the countersink is obtained and precisely at the desired height.
