Overview
The DEWALT DCF845D1E1 is a 20 volt cordless impact driver spinning up to 3400 RPM. The D1E1 kit code on DEWALT impact drivers typically pairs the tool with a battery and charger, so this listing likely covers more than the bare driver.
At 5.53 pounds the listed weight is heavier than a bare compact impact driver usually runs, which fits with this being sold as a kit including battery and charger rather than tool only. Confirm exactly what's in the box on the product listing since battery count and charger type affect that total weight.

Who it's for
Fits users who want a cordless impact driver ready to work out of the box for fastening, deck building or general assembly. Less suited to anyone who already owns 20 volt batteries and only wants the bare tool.
Strengths and trade-offs
