One word of caution when you read the specs, you may be shocked at the maximum torque ratings of hydraulic impacts. This one is 500 in-lbs vs the DCF860 (non-hydraulic) at 2500 in-lbs. Yes, the maximum torque of the DCF860 is five times higher. The way a hydraulic impact driver works is to buffer the impact with the hydraulic fluid (oil), which reduces the peak impact. However, this buffering sustains the time of each impact, so you end up with less torque but for a longer impact. For that reason, taking the peak torque ratings at face value can be deceptive and real-world testing is the best way to assess the true utility of the tool.

Yup, my experience with this impact driver is clients are so much happier not having their ears blown out indoors, and I'm happy not having to put on full ear protection every time.
Closes the gap so significantly that I barely notice.
