1/2-Inch Drive: The Popular Kid in the Wrench World

Choosing the right impact wrench is a bit like finding the right tool for the job—it’s all about knowing what you need. The 1/4-inch drive is perfect for light work, while the 1/2-inch is the go-to for most people. For heavy-duty jobs, you’ll want the 3/4-inch or even the 1-inch drive to handle those tough tasks.
