DeWalt DCF900P2 Impact Wrench vs DeWalt DCF899M1 Impact Wrench

The DCF900P2 is the stronger tool: about 1,030 ft-lb fastening and 1,400 ft-lb breakaway torque, four speed settings and two 5.0 Ah batteries. The DCF899M1 is lighter at 7.2 lb and easier to fit into tight spots, but it makes about 700 ft-lb fastening and 1,200 ft-lb breakaway. Buy the DCF900P2 for heavy automotive and industrial work; buy the DCF899M1 if you want a lighter wrench for general fastening and already have batteries.

• Choose the DCF899M1 if you want a lighter, more compact wrench for everyday fastening and don't need the extra power.
