    FAQs

    Will this impact wrench damage my dewalt batteries?

    No. The wrench includes a built-in battery management and protection system that helps prevent over-discharge, over-current, and short circuits. When the battery reaches a low-voltage threshold, the system automatically stops operation to help protect your Dewalt batteries and maximize their lifespan.

    Can this impact wrench remove rusted bolts?

    Yes. With up to 1,100 N·m (800 ft·lb) of max torque and a powerful impact mechanism delivering up to 2,900 IPM, this impact wrench is designed to help break loose stubborn, over-tightened, and rusted fasteners. It’s ideal for automotive repairs, workshop maintenance, and heavy-duty fastening jobs where extra power is needed.

    How many speed settings does this impact wrench have?

    The impact wrench features 4-speed control settings, allowing you to adjust the power and speed for different tasks. Lower speeds provide better control for delicate fastening and smaller bolts, while higher speeds deliver maximum power for heavy-duty applications. This helps reduce the risk of over-tightening and gives you more control over every job.

    Yes. With up to 1,100 N·m (800 ft·lb) of max torque and a standard 1/2" square drive, this impact wrench is ideal for automotive tasks like removing and installing lug nuts. It helps make tire changes faster and easier, especially when dealing with tight or over-torqued bolts.

    What does 1/2" drive mean? What size sockets does it use?

    A 1/2" drive refers to the size of the square drive an impact wrench uses to attach sockets. It is one of the most common sizes for automotive and heavy-duty applications, allowing you to use a wide range of 1/2" drive impact sockets for tasks like changing tires, repairing vehicles, and fastening large bolts.

    What does the 5-year warranty cover?

    Our 5-year warranty covers defects in materials and workmanship under normal use. This includes issues such as motor failures, electrical component defects, and product malfunctions caused by manufacturing problems.

    The warranty does not cover normal wear-and-tear parts, such as blades, brushes, filters, seals, or other consumable components that naturally wear out during use. Damage caused by misuse, accidents, improper maintenance, or unauthorized modifications is also not covered.
