The consensus
What reviewers found
Synthesized across the trust-weighted source mix below.
Across the reviewers we read, the DeWalt DCF870B hydraulic impact driver is the consensus pick when noise and smoothness matter most, holding a 4.7 rating over roughly 720 reviews. DeWalt's listing advertises up to 57% quieter operation and up to 40% faster driving, and r/Dewalt owners back the experience enthusiastically—one says it 'stays with my daily tools' and another calls the impact function 'so smooth,' while a third highlights that it's 'super quiet' with a 20-minute LED light option. A Lowe's listing summary similarly reports a consensus around its balance of power, control, and noise reduction.
What reviewers liked
- Owners consistently praise the quiet, smooth hydraulic operation for indoor and sensitive work
- Useful 20-minute LED light option noted by r/Dewalt users
- Solid 4.7 rating with broadly positive community sentiment
Where it falls short
- r/Dewalt torque discussion flags output below even a 12V impact and far below standard 20V models
- Owners say it struggles with repeated lag bolts
- Sold as a bare tool, and supporting evidence is medium-trust community rather than independent testing

The critical, honestly-surfaced caveat is torque. An r/Dewalt thread specifically measuring the DCF870 notes its output is 'significantly lower than even a 12V impact' and well under standard DeWalt 20V impacts, and another owner concedes 'it's def not as strong as the 887/850.' Even fans say it can handle 'anything except repeated lag bolts.' This is a comfort-and-control tool, not a maximum-power one, and the supporting community evidence is medium-trust rather than independent testing—hence the slightly lower score despite genuine enthusiasm.

Honestly I don't have an issue with the noise of my impact. It's the oscillating tool that I have an issue with. When they make a less noisy one ...
