I got it as a gift. To lay around at home, just in case, it will do, but for professional use there is nothing good there (I thought that Bosch had at least a magnetic extension cord for bits of norms. But it turned out to be complete . The self-tapping screw does not hold at all. ) And I drilled on concrete few people use when there is a puncher. And the rest is easier to buy separately, it will be cheaper.
