Bosch GSB12V-300B22 12V Max Brushless 3/8 inch. Impact drill kit with (2) 2.0Ah batteries. Read carefully, different models are sold here. With two batteries, battery life is rarely an issue. And 12V oddly provides enough power. The drill has two speeds, which is very convenient for turning screws and then drilling wood with small drill bits. It's compact and lightweight. This model also has an impact drill function that works for both drilling and loosening stuck screws. The chuck has a built-in lock so you can tighten it easily. However, you have to pay attention to how the bit sits in the drill chuck, as it is sometimes loose due to the very short jaws. Overall a great tool.
