What I Look for Before Buying
Before I choose a DeWalt Cordless Impact 20V, I always check a few important things. I want to make sure the tool matches the kind of work I do most often.

Power and Torque
I always compare the torque and speed settings because they tell me how much work the impact driver can handle. If I plan to drive long screws or work with tougher materials, I want stronger torque.

Comfort and Grip
When I hold a tool for a while, comfort matters a lot. I like a handle that feels secure and balanced in my hand. A good grip helps me stay in control, especially when I am working on harder materials. I also appreciate a design that reduces vibration, since that makes the tool more comfortable to use.
Features I Find Useful
I usually look for helpful features like LED lights, variable speed control, and quick bit changes. The LED light is especially useful when I work in dark corners or inside cabinets. Variable speed control helps me manage precision, and a fast bit-release system saves me time when I switch between tasks.
