I just purchased a 18v combo set from HD ( R968 ) and have a couple questions that I'm hoping some one on here might be able to answer. The driver/drill when set on the 2 gear makes a clunking kind of noise when the trigger is released, is this normal? Also has anyone else used this set and if so what do you think about it? Very cool hand held saw, but haven't used it yet. Any comments? Thanks. Have had a 2400 table saw for a few years and like it.
