What are the Differences Between Cordless and Cored Impact Wrenches?

We all know that having a good impact wrench is important when working on your car or truck. However, many people overlook the importance of a good impact wrench when working on their home projects. When it comes to your home, your impact wrench can mean the difference between a smooth, quick project and an annoying, time-consuming struggle. That’s why, in this article, we’re going to take a look at the two main types of impact wrenches on the market—corded and cordless. We’ll compare the features and benefits of each, and help you decide which one is right for you.

What is an Impact Wrench?

An impact wrench (also called an “impact driver”) is a tool with a motorized spinning head (called an “impact mechanism”) that delivers a powerful rotating force to a socket or other kind of connector to rapidly break it free from any kind of fastener. An impact wrench is very useful for tightening fasteners that have rusted or frozen, or for removing stubborn objects that are difficult to grip with your fingers. They’re also great for working in confined spaces and driving into hard surfaces like concrete and asphalt. Most people use impact wrenches when working on cars and trucks. However, you can use one on just about anything that has a standard socket, including light fixtures, plumbing, piping, sheet metal, and so on. There are different type of impact wrench including:

  • Electric Impact Wrench
    • Corded Impact Wrench
    • Cordless Impact Wrench
  • Air/Pneumatic Impact Wrench

What is a Corded Impact Wrench

The corded electric impact wrenches are powered by an AC (Alternating Current) power supply which is used for performing a variety of tasks. It’s basically a drill-type tool with an attachment that is capable of delivering a powerful punch or torque. They are designed to be operated on hard surfaces like concrete or asphalt, so they’re ideal for use in construction or maintenance jobs.

Corded electric impact wrenches are used to tighten bolts and nuts by applying an external force. They can be used for different purposes, such as working in confined spaces, drilling into metal, or tightening screws.  They can be used on a variety of surfaces, including metals, wood, plastic, or concrete. The corded electric impact wrench is one of the most commonly used tools in the home improvement industry.
