Corded Impact Wrenches

Start with the job and the range of nuts and bolts you need to handle. Defining the application first helps avoid over- or under-sizing the tool; see what tasks are you choosing a handheld power tool for.

Torque is one of the main impact-wrench specifications because it indicates how much turning force the tool can apply when tightening or loosening a fastener. Compare models with the guide to torque (N·m).

Check the square-drive size and socket compatibility. Impact wrenches should be paired with sockets designed for impact loads and matched to the drive size; see how to choose an impact socket.

For corded models, input power is useful when comparing tools for sustained or demanding work, but it should be considered together with torque and intended use. See how to choose tool power (W).

Rotational speed affects working speed and control. Higher RPM does not by itself mean higher tightening force, so compare it together with torque; see what is rotational speed (RPM).

Convenient reverse operation, clear controls and suitable protective features matter during both tightening and loosening. Also review tool safety systems and their purpose.

High-torque models can be heavy, so grip design, balance and overall weight become important during extended use. Compare these factors with tool ergonomics, weight, and safety systems.

Choose according to frequency and intensity of use: occasional light work and daily professional duty place different demands on the tool. See differences between professional and household power tools.
