A bright LED with a 20-second trigger release delay improves visibility in dim spaces, making it a practical choice for overhead or confined-space installations. The pair provides versatility for everyday fastening and drilling tasks without overbearing weight.
DEWALT ATOMIC 0.25″ Impact Driver

The ATOMIC model delivers 1,825 in-lbs of torque and 3,250 RPM, supported by a variable 3-speed trigger and an integrated LED work light. This configuration emphasizes precise control for fasteners while maintaining strong driving performance. The compact brushless design reduces heat and maximizes efficiency, making it suitable for frequent, repetitive fastening tasks in carpentry, cabinetry, or general construction.
DEWALT DCF860B 20V MAX XR Impact Driver

As a high-torque bare tool, the DCF860B offers up to 66% more torque than earlier models and can drive screws quickly with a 63% faster driving speed. Its pro-level control comes from a variable speed trigger and a 3-speed mode, enabling installers to tailor performance to the task. This model is ideal for professional users who need powerful performance in a compact, cordless package.
DEWALT DCF900B 20V MAX 1/2″ Impact Wrench

The DCF900B offers a strong fastening torque with 1,030 ft-lbs and 1,400 ft-lbs breakaway torque, supported by four-mode speed settings and a variable speed trigger. It is designed to prevent over-tightening and fastener run-off through Precision Wrench control, ensuring consistent performance on heavy-duty jobs and automotive tasks where high torque is essential and control cannot be compromised.
DEWALT DCF845B 20V XR Impact Driver

The DCF845B features a brushless motor delivering 1,825 in-lbs of torque and 3,400 RPM for aggressive fastening. With a 3-speed setting and a variable speed trigger, this tool provides pro-level control for large-diameter screws and heavy-duty applications, ensuring efficient, precise performance in demanding environments.
Buying Guide: Key Considerations For Selecting A Cordless Impact Driver
Power and torque: Look for models offering torque in the range of 1,000–2,000 in-lbs for most heavy-duty tasks. Higher torque translates to faster driving through tough fasteners and larger screws, but ensure the tool remains controllable with a reliable trigger and multiple speed options.
Brushless motors: Brushless designs tend to deliver longer life and better efficiency. They maintain performance under load and typically generate less heat during extended use, which helps sustain battery life and tool longevity.
Speed control: A variable speed trigger and multiple speed modes allow you to fine-tune drive speed for delicate work and heavy-duty driving alike. This helps prevent overdriving or cam-out when working with different screw types and materials.
Size and weight: Compact tool profiles are essential for working in tight spaces, overhead applications, or prolonged use. Weight distribution affects fatigue, so a tool with a comfortable grip and balanced weight is desirable for extended projects.
Batteries and runtime: Kits with efficient 4.0 Ah equivalents or multiple batteries provide longer runtime between charges. Consider whether the kit includes a fast charger, and verify compatibility with your existing 20V MAX platform if you already own DEWALT tools.
Accessories and ergonomics: Features like integrated LED lighting, ergonomic grips, and tool-free bit changes improve usability. A well-illuminated work area reduces mistakes and increases efficiency, especially in dim spaces.
Tool compatibility: If you already own a line of DEWALT 20V MAX XR tools, sticking with the same platform can maximize battery interchangeability and overall value. Bare tools offer flexibility if you already have batteries or want to minimize upfront cost.
Noise and comfort: Some models emphasize low-noise operation, which is beneficial in shared workspaces. Consider hydraulic or quiet drive innovations if you work near others or in noise-sensitive environments.
Application focus: For automotive, construction, or cabinetry tasks, select a model that aligns with your typical fasteners and screws. Some drivers excel at high-torque driving, while others emphasize control and precision for smaller screws.
