It is easy to use and simply needs connecting to a dust extractor; it is tool independent and functions with all drilling tools. There is no assembly required for it to fit a dust extractor and adds no extra weight to the machine, it is designed for use with the Bosch Click & Clean System but direct extractor connection is also possible. It is suitable for core cutters with up to 162mm diameter and works just as well during wet drilling.
