Impact Driver DeWALT DCF850E2T-QW 3250 RPM, 18V, 2 Batteries

The DeWALT DCF850E2T-QW is an 18V cordless impact driver designed to deliver high rotational speed and ergonomic handling for fastening and drilling tasks. With a maximum idle speed of 3250 RPM and a pistol-style handle, the tool balances power and user comfort. The compact, lightweight construction at approximately 0.9 kg and a quick-release chuck support fast bit changes and extended use on site or in workshops. Two included Lithium-Ion batteries provide extended runtime to reduce interruptions during projects.

Advantages

The impact driver combines high no-load speed with a compact, pistol-handle design to improve control in tight spaces. A quick-release chuck simplifies bit changes without additional tools, while the integrated LED light improves visibility in low-light conditions. The battery-powered design removes cord constraints, and the lightweight housing reduces fatigue during prolonged use.

Suitable for

• Driving and removing screws and fasteners in wood, metal, and composite materials
• Assembly and disassembly work in carpentry and joinery
• Maintenance and installation tasks where cordless mobility is required
• Construction site fastening where compact size and quick bit changes are advantageous

How to use

Insert a charged 18V battery into the tool until it locks into place. Select the appropriate driver bit and secure it in the quick-release chuck. Adjust speed as required by using the variable trigger control and apply steady pressure while driving or removing fasteners. Use short bursts when starting a fastener to improve accuracy and reduce cam-out. After use, remove the battery before storing the tool and keep bits and batteries in dry, ventilated conditions.

Recommendations

For optimal performance, use charged manufacturer-recommended 18V Lithium-Ion batteries and compatible DeWALT bits. Operate the driver within its speed range and let the tool do the work—avoid excessive force. Wear appropriate personal protective equipment such as eye protection and gloves, and follow local safety regulations when working on construction sites or in confined spaces.
