Abstract

Perforated drill pipe for quarries and mines, essentially characterized in that the male and female heads have, in the areas of contact with the central tube, blind holes according to axes perpendicular to the longitudinal axis of the assembly, holes that are coincident with others made for this purpose in the tube, so that inclusion in them is allowed, some anchor bolts, whose outer face is tucked under the outer contour of the tube, making a closure or welding that connects the python to the tube and heads.
