J bought this drill there a month to a number of small jobs (I am not a great handyman). This drill has shown hyper-practical with its easy system that allows tightening and loosening very quickly wicks. This drill is mighty in speed for all walls (concrete, plaster) I have presented itself with wicks 13. It is relatively light so we can pierce height resign without an arm. With my model was delivered a set of 4 bits BOSCH I have not seen mentioned. a good buy.
