Cool, thanks for the response.

[20v max dcd985 question]

I just bought this drill and am learning how to use it. On speed 2 and 3 when you release the trigger it makes kind of a clacking sound and the chuck loosens on bit.  I took the first one I bought back but the second one does it as well.  Is that some kind of a feature? Not sure why it would be.  Anyone know about this?
