What does the term UWO mean?

UWO stands for Unit Watts Out which is a calculation meant to tell you the difference in power between two or more different drills. It takes the drill’s speed and torque and multiplies them, and then it divides the result by a constant. So, for example, if you wanted to know how much power a 500 inches/pounds drill has at 600 RPM over another drill of 475 inches/pound torque at 650 RPM, then UWO is the measure to use.

Do all Dewalt models come with batteries and a charger included?

It depends. However, it’s good to counter check first before making a decision instead of assuming.
