Overview

DeWalt's DCF845P1 kit runs on the 20V Max platform, spinning to 3400 RPM at a listed 5.1 pounds. It's built as an impact driver kit rather than a bare tool.

The 20V Max platform gives this driver a higher RPM ceiling than compact 12 volt drivers, at the cost of extra weight in the tool. No torque figure is listed, so speed and platform compatibility are the confirmed selling points here.

Who it's for

DeWalt 20V Max owners who want a faster driver for general fastening work across their existing battery lineup. Not the pick for anyone prioritizing minimum weight for overhead jobs, since compact 12V drivers run lighter.

Performance notes

Running up to 3400 RPM on the 20V Max platform, the DCF845P1 spins faster than typical compact 12 volt drivers, which speeds up repetitive fastening. At 5.1 pounds it's noticeably heavier than sub-2 pound compact drivers, a trade that comes with the larger 20V battery and motor rather than a flaw in the tool itself.
