DeWalt DCF840N-XJ 18V Brushless Compact Impact Driver (Body Only)
The DeWalt DCF840N-XJ 18V Brushless Compact Impact Driver (Body Only) is a powerful cordless impact driver designed for fast, controlled screwdriving and fixing in construction, installation and maintenance work. Built around DEWALT's XR 18V platform, it delivers up to 192Nm of torque with a compact, lightweight form factor that is ideal for working in tight spaces and at height. A high-efficiency brushless motor, 3200rpm no-load speed and 4200bpm impact rate combine to provide strong driving performance while helping to maximise runtime when paired with compatible XR batteries. The 1/4" hex tool holder allows quick bit changes, and the integrated 3-LED work light improves visibility in dimly lit areas, supporting accurate fastening on site. With a soft-grip handle and durable aluminium gearbox housing, this impact driver is well suited to professional trade use across carpentry, framing, decking and general construction tasks. Supplied as a bare unit, the tool does not include battery or charger and is compatible with DEWALT 18V XR lithium-ion batteries and chargers.
