If you do not want to spend very much money for a drill, a drill but still of good quality want, you are exactly right in this Bosch drill. The corresponding impact drill to get with this drill quite well by thick walls. Although it took a while, the drill has been working very satisfactorily twice through a 40 cm thick outer wall. The top saw then still look as good as new. The quality is so absolutely satisfactory. The Amazon price is unbeatable! At the hardware store, I would have paid almost twice as much.
