DEWALT 20V MAX 1/4 Inch Hydraulic Impact Driver,Quiet, Brushless Cordless XR Extreme Runtime, LED Halo Ring, Tool Only (DCF870B)

Across the reviewers we read, the DCF870B is treated as a specialty pick rather than a do-everything impact — and reviewers are remarkably consistent about why. protoolreviews.com, a high-trust expert source in this candidate's signals, lists quiet operation, a well-balanced design, plenty of power for common fastening, and an extended-runtime LED as the headline pros. r/Dewalt users go further, with one thread declaring the hydraulic mechanism makes traditional ratcheting impacts 'obsolete' for screw driving because there's no bounce and tightness is easier to feel.

Verified-purchase reviews at homedepot.com echo that the tool is genuinely quiet, compact, and not overly heavy. That's the use case reviewers keep returning to: indoor finish work, cabinet installs, occupied jobsites, and anyone tired of the high-pitched hammer of a conventional impact.

The disagreement worth surfacing comes from r/Dewalt itself: one thread explicitly notes the DCF870 is rated significantly lower in torque than standard 20V impacts (and even some 12V models), which makes it the wrong tool for breakaway-heavy tasks. The consensus is that if you want one impact driver, the DCF845 is the safer pick; the DCF870 is for buyers who specifically value noise and control over peak power.
