DeWalt 20V Max Quiet Hydraulic DCF870 vs DeWalt DCF787C1 20V MAX Impact Driver

Buy the DCF870 if you drive big screws and lags all day and want a quieter tool with two speed settings. Buy the DCF787C1 if you want a complete kit for general fastening and light jobs. The DCF870 is the more capable driver: its hydraulic mechanism is rated far higher on torque and is advertised as up to 57% quieter and up to 40% faster than standard impact drivers. The DCF787C1 is the simpler, lighter-duty tool, and its larger owner base rates it slightly lower.

  • Choose the DCF870 if you drive large screws and lags, work in noise-sensitive or cold places, and already own DeWalt 20V batteries.
  • Choose the DCF787C1 if you want a ready-to-use kit with a battery, charger and bag for everyday fastening and tight-space work.

Questions and answers

Which is better for driving long lags and framing screws?
The DCF870. Its hydraulic drive is built for large fasteners, with two speed settings and a higher impact rate. The DCF787C1 is better suited to lighter fastening.
Which is quieter?
The DCF870. DeWalt rates it up to 57% quieter than standard impact drivers. The DCF787C1 is a conventional impact driver with no quiet claim.
Which lasts longer?
Both use brushless motors. The DCF870's hydraulic mechanism is a more complex design, while the DCF787C1 is a simpler tool with a long track record and many more owner ratings.
Is the DCF870 worth stepping up to?
Yes if you drive large screws often, work in cold weather or need lower noise. If you mostly fasten smaller screws, the DCF787C1 covers it.
Does the DCF787C1 come with a battery?
Yes. The kit includes a 1.3Ah 20V MAX battery, a charger and a kit bag. The DCF870 is sold as a bare tool.
Do both use the same batteries?
Yes. Both run on DeWalt 20V MAX lithium-ion batteries, so packs and chargers are shared across the line.
