If I need max torque then I'll grab my DEWALT DCD710B. He's already put it to good use on our new house. There is only one thing I don't really like. Am very glad I decided to order this one. I charged a battery in about 3 hours.
DEWALT DCD710B Features & Specs
Maximum initial voltage on batteries (measured without a workload) is 12 volts, under a workload nominal voltage is 10.8

Turn the chuck until you hear a loud click. Smooth operation, works great. The DEWALT DCD710B is a labor saver. The light and the belt hook are great features. The Power Drill is a good drill/driver.
