An unexpected benefit was that it would work as a screw driver in impact mode. I'm not sure if this was intended behaviour but it seemed to work well. Unifortunately this drill broke recently.
So I'm looking for a replacement. The drill I had is discontinued so I can either get a cordless non combi/non impact replacement or buy some thing slightly more expensive.
However I'm a bit confused as combi drills are often sold with additonal impact drivers. Is it the case that most combi drills will not also work as an impact driver? In which case I won't bother with the combi as a cordless hammer drill action isn't important to me.
