Our Take

Best for: Pros and serious DIYers needing a quiet, powerful impact driver.

The DEWALT DCF870B is a standout in the hydraulic impact driver category. Its advanced mechanism delivers consistent power even in cold temps, and the 57% noise reduction is a for indoor or residential work. The 9-LED halo ring provides excellent visibility without shadows. Speed settings 1 and 2 are optimized for different fastener sizes, and the belt hook keeps it handy. It's one of the most compact hydraulic drivers, perfect for framing and cabinetry in tight spots. The main tradeoff is that this is a bare tool, so you need a DEWALT 20V MAX battery and charger. 99 (23% off $219), it's a strong value for pros who already have the battery system.

Price Analysis

At $167.99, this is 23% off the $219 list price, saving you $51.01. Given the premium hydraulic design and performance gains, this is a solid deal for a pro-grade tool. Comparable hydraulic drivers from other brands often cost more.
