Handy, powerful, useful. Great tool.
Very useful tool for all kinds of shop and household projects. Have used it on many things. Can use carefully without the impact feature for screws and smaller bolts. Can use the impact feature for larger or stuck bolts and screws.

Small and mighty
I just used this bad boy to replace an alternator in a 2009 Murano in 5 hours and I wouldn't have achieved that without this (iykyk). We have all DeWalt tools in our garage so it's nice to have a good impact. Great torque, lightweight, compact, and mighty. CAn't go wrong.

It's worth it.
Just exactly what it should be. Looked good and works great. It is a lower RPM than I expected and lower than my others.

Excellent power and precise speed control
The speed control on this impact driver is excellent. It responds smoothly to pressure, letting you work slowly when needed and still giving you plenty of power for tougher jobs. The tool feels solid, well-balanced, and easy to handle for long periods. A great upgrade for any DIY or professional toolbox.

1/4 inch Dewalt impact driver
Always have good experience with Dewalt stuff this Atomic version seems to have a little more power- still light in weight- low noise but that’s never really been an issue using these electric units over air operated ones. Portability is great as I’m old enough to remember dragging around hoses or cords!
