Abstract
On a drill stand, a drilling member is movable between an inactive position spaced from the material to be drilled and an active position in contact with the material to be drilled. A marking element is mounted on the stand and is slidably movable between a retracted position and a marking position. In the marking position, a pointer on the element can mark the drilling axis on the material to be drilled. With the drilling axis located, the drilling member can be moved into the active position to commence drilling.
