Dewalt has announced a new DCF870 20V Max cordless quiet hydraulic impact driver.
This will be Dewalt’s quietest cordless impact driver, and is said to be “the industry’s highest rated max torque hydraulic impact driver designed for noise-sensitive environments.”
Dewalt says that it can deliver up to 57% quieter operation.

Dewalt also says that the new DCF870 oil impact driver “delivers up to 40% faster driving with consistent performance in demanding applications and cold temperatures.”
It has a built-in worklight with 9 LEDs, and a 20-minute worklight mode for lighting up dark spaces in a pinch.
Dewalt’s going after the Milwaukee M18 Fuel Surge, saying that their new DCF870 oil impact delivers:
Up to 195% Faster Driving (3″ x 3/8″ lag bolt into PT 4×4 using DCBP034 vs. Milwaukee 2760 using 48-11-1820)
Up to 250% Faster Driving 5 Lags (Total driving time of 5 consecutive 3″x 3/8″ lag bolts into PT 4×4 using DCBP034 vs. Milwaukee 2760 and 48-11-1820)

The 20V Max DCF870 will be available in tool-only format, DCF870B, and also in a kit with compact PowerStack battery and charger, DCF870E1.

Discussion
I am all for a quieter impact driver!
Oil impact drivers have a different performance characteristic compared to traditional impacts, and so it will be very interesting to see how the new DCF870 compares with Dewalt’s also-new DCF860 impact driver.
The DCF870 is part of Dewalt’s 20V Max lineup and has been given XR branding, denoting that it has a brushless motor and premium features.
Dewalt points out on their product page that the new DCF870 impact bests the Milwaukee M18 Fuel Surge, which launched almost exactly 8 years ago.
It’s great to once again see some competition in this space!
