As apparently also other buyers has exploded to me at the first hole, the drill chuck. So this part of the unit is more than useless, I would even say real scrap. But as the field of application should be another, this fact is to get over. Drilling and chiseling to long without problems and for domestic use sufficient. Those who expect more here should look for other prices! Mannesmann M12590 drilling and chiseling hammer 850 Watt 3 features
