Best Impact Wrench Guide – Cordless Impact Wrenches vs Electric Impact Wrenches vs Pneumatic Air Impact Wrenches

There are some tools that are a "must-have" in anyone's garage. Along with a nail gun that saves you lots of time, an air hammer that can cut through stone or metal, a scroll saw for those of you who love woodworking, you also need a quality impact wrench that is effective in removing and tightening screws and bolts. Everyone needs one, as sometimes using manual tools is quite dangerous and takes precious time.

An impact wrench is necessary for both professionals and amateurs, and we're sure you'll have to use it sooner or later. Large, rusty screws are really annoying, and you might spend a significant amount of time removing them. This is why an impact wrench will make the job a lot easier for you, and will remove the screw or bolt in a matter of seconds. It is especially designed to remove all difficult bolts, screws and nuts, and also fasten them.

So, whether you are a professional or a home worker, if you want to work efficiently and get your job done quickly, an impact wrench is what you need.

Like all power tools, impact wrenches have different prices depending on their features, speed settings and types. A high-quality impact wrench that offers two times more run time than other impact guns and allows the operator to choose between two fastening models can cost around $400. However, there are quality models that cost around $100 and feature compact sizes that offer maximum comfort.

It’s best to stay away from cheap impact wrenches, as they’re made with poor-quality materials and won’t get the job done as well as a quality one. Plus, when getting any power tool, sacrificing quality for price may even pose safety risks.


Impact wrenches are used in many industries and by many professionals. Whether you are a beginner or a professional, it might be difficult to choose the right one, as there are so many models with different features on the market. So, we have broken down the basics and will tell you exactly what you need to know before purchasing this tool.

Here you go:

  • Torque - The key feature of an impact wrench is how much torque it generates while operating. There are models that have a maximum torque and other models that feature multiple torque settings. The higher the torque, the more capable the impact wrench is. Look for a minimum load of 1700 in.-lbs.
  • Weight - Always look for a lightweight impact wrench, as heavier ones are not great for long projects and are harder to control, especially when you're tired.
  • Size - When talking about impact wrenches, the smaller the better. Large impact wrenches are harder to operate. Look for an impact gun that is easy to hold and operate.
  • Impacts per Minute - The higher the number of impacts, the faster the impact wrench will be able to drive screws and loosen bolts.
  • Load Speed - If the load speed is high, it means the impact wrench will fasten screws more quickly. However, if the speed is high, the torque will be low. It's better to prioritize the torque.
  • Drive Size - There are two popular sizes: 1/2" and 3/8". 1/2" impact guns are great for most applications, while the 3/8" ones have less torque.
  • Ergonomics - Always consider ergonomics when getting any tool. Quality impact wrenches are easy to hold and feature comfortable grip materials.
Construction and Design

Every mechanic, professional or home worker should have an impact wrench. They can be used for loosening lug nuts and in high-torque situations. They're generally divided into two categories based on the type of power they use to produce torque: pneumatic-powered wrenches and electric-powered wrenches.

Pneumatic air impact wrenches are powered by compressed air and were the first to be designed. They are available in a variety of sizes. Generally speaking, the higher the drive size, the larger the amount of torque they produce. Their main advantage is that they can be used constantly, as they don't need any power source.

Electric impact wrenches fall into two categories: corded and cordless. Corded impact wrenches have to be connected to an electrical source. They are quite rare nowadays, as manufacturers prefer to produce cordless ones. Corded impact wrenches can be used non-stop if there is a source of power, while cordless impact wrenches use batteries and, even though they offer you portability, they don't offer the same power as corded or pneumatic impact wrenches.
