How to Match Your Impact Wrench to the Job

Choose a 1/2-inch model when your work frequently involves larger automotive, construction, or heavy-duty fasteners that call for a substantial socket setup.

Look at a 3/8-inch compact wrench when access and manoeuvrability are priorities, particularly around vehicles, machinery, and confined workspaces.

Consider the voltage, torque class, drive size, and battery platform together so your impact wrench matches both the demands of your projects and the cordless tools you already own.
