ABSTRACT:
A drill for drilling crossties, particularly for use in the railroad sector, comprising a protective enclosure which is formed by a movable portion and by a fixed portion and is suitable to completely cover a chuck of the drill and a drilling bit coupled to the chuck; sliding means which allow the sliding of the movable portion with respect to the fixed portion when the movable portion is placed at an area to be drilled and at the beginning of the drilling operation; and resilient means adapted to bias the sliding of the movable portion with respect to the fixed portion and suitable to be loaded by the penetration of the drilling bit and, at the end of the drilling operation, to be released for the quick disengagement of the bit from a hole formed during the drilling operation.
