This is a (4) piece 20V cordless tool set made by Dewalt. It is previously owned and all the tools work well. The impact wrench shows more wear than the other tools but still works well. It comes with (2) 20V batteries, a charger, a 1/4" impact driver model#DCF887, a 1/2" impact wrench model#DCF889, a 1/2" hammer drill model#DCD996, a worklight model#DCL040, a side handle and a carrying bag. Due to the fact that this is a previously owned set, we cannot warranty the life of the batteries, or the charger, however, everything is working well.
