Not only hammer drills hit the wall – as the saying goes – when faced with walls as hard as steel, the user, too, will have to throw in the towel eventually, seeing as the force of impact drilling machines is transmitted by pushing. Connoisseurs therefore use Trotec rotary hammers, because when the impact drill reaches breaking point, our rotary hammers only gain momentum and break through every stone or concrete without difficulty. Equipped with a pneumatic hammer mechanism, the force transmission of the rotary hammers’ powerful blows is effected by means of compressed air. Hence, the required contact pressure is considerably lower if you use a rotary hammer.
