Summary
Compact, well built and with solid torque for tight-space driving, the DeWalt 20V MAX XR 1/4" Impact Driver is reliable in trades use, though as a bare tool it requires batteries and charger separately.
Findings
From practical field use, the DeWalt DCF870B feels sturdy in the hand and forgiving in everyday tasks. The overall build quality is strong: a compact profile with a robust housing and a comfortable rubber overmould that stands up to site knocks and repeated handling. The 1/4" hex drive makes bit changes quick and the chuck remains confident under typical driving loads, which is especially useful when swapping between deck screws, cabinet fixings, and lighter lag bolts. The brushless XR motor delivers consistent performance across the three speed settings, allowing me to tailor torque to the job without overdriving or cam-out, and the tool remains cool enough for successive fastenings in moderate sessions. In tight spaces, the short length and balanced weight help reach awkward joists and studs without sacrificing control. The LED work light is practical in dim corners and the overall trigger response is crisp, giving steady feedback through the drive. Used with quality bits and a capable 20V XR battery, it feels reliable for daily site use and provides a good balance of speed and control for most common timber and fastening tasks.
