Overview
A contractor who already owns compatible batteries gets the DeWalt DCF870B as a quiet hydraulic impact driver with a quarter-inch drive. It is brushless, has two speeds and adds a halo-style LED around the chuck.
Reduced noise is the headline: the hydraulic mechanism is described as quiet, which matters in finished rooms and long sessions. The tool arrives without a battery, so what you already own decides whether it is ready to use.
Who it's for
Remodelers and installers on the DeWalt battery system will use the compact body and the lower noise. Buyers starting without a battery platform should expect an extra purchase before first use.
Pros and cons
- Quiet hydraulic impact mechanism
- Brushless motor listed
- Two speeds for control
- LED halo ring lights the work
- Battery not included
- Charger not listed
- Quarter-inch chuck limits bit choice
Performance notes
Torque and the maximum speed set how large a fastener it drives and how quickly. The hydraulic mechanism cushions each impact, which is where the quieter running comes from. A brushless motor and variable speed help control on small screws.
