best electric impact wrench

If you are having trouble removing stubborn bolts, an electric impact wrench is a power tool you should be looking to invest in. Although rusted and worn bolts can be removed manually with considerable effort, an impact wrench takes the hard work out of such jobs, saving you a considerable amount of time. Unfamiliar with impact wrenches? Our buying guide explores the main factors you should be assessing when selecting the best electric impact wrench for your needs.

Impact Wrenches Explained

Although impact wrenches come in a variety of designs, they all work in much the same way. At first glance, most impact wrenches resemble electric screwdrivers. However, they work very differently and are used to remove or tighten bolts. The interior of an impact wrench features a rotating mass. The impact wrench motor attains energy from this rotation, and is pushed forward towards an anvil situated at the end of the impact wrench. This process creates a huge amount of torque that can not be achieved manually. Despite the significant amount of torque generated by an impact wrench, the user will only feel minimal force at the moment of impact.

Impact wrenches are also incredibly precise. This makes them a safe solution for securing bolts to wheels or adding bolts to heavy-duty machinery. Although the core function of impact wrenches remains the same between models, individual models vary when it comes to things like socket size, power sources and overall shape.

Electric Impact Wrenches

Although electric impact wrenches are not as powerful as the compressed air varieties you might find in a car repair shop, they are still incredibly efficient at doing what they do. When selecting an electric impact wrench, you have two main varieties to consider. One of these is the kind that connects directly to a mains power supply. Although these are reliable and mean you do not have to worry about constantly recharging internal batteries, you will need to ensure you have a decent cable length to provide you with access to car wheels and other work areas.

Impact wrenches with internal batteries are a good alternative. They provide you with full flexibility and mean you do not have to stay close to a mains power supply. However, the addition of an internal battery means the carrying weight of the power tool is more substantial.

Torque Levels

Torque is important to consider when selecting an impact wrench. The higher the torque, the more functional your impact wrench. Most electric impact wrenches will provide you with several torque settings that you can choose between. Opt for impact wrenches with a good selection of torque if you want a power tool that is fit for a variety of tasks. However, you should be careful not to select too much torque when using an impact wrench. Operating an impact wrench at too high a torque level can damage bolts and the items they are fastened to.

Ergonomics

Although impact wrenches are designed so you do not have to bear the brunt of the torque behind them, you should still go for an ergonomic model that is easier to handle. Choose an impact wrench with a comfortable handle that includes a rubber texture. This will dampen vibration as you use the wrench, which will make it easier to operate.

Socket Size

Most impact wrenches will support compatibility with various socket sizes, as well as allow you to connect adaptors. Go for an impact wrench that supports a good selection of socket sizes if you want to be able to remove and tighten a good variety of screw and bolt sizes.

Before You Buy

By now you should have a clear idea of what to look for when selecting a suitable impact wrench for your needs. A cordless design is arguably the best option, as this will provide you with maximum flexibility when it comes to accessing work areas. However, you should also ensure any integrated battery carries sufficient charge so your power tool can be used for long spells without requiring constant reconnection to a power supply.

A brushless motor will also provide you with more reliable performance, as well as ensure your impact wrench operates for as long as possible. Automatic stop features are also handy to have, as they will prevent powerful impact wrenches from continuing to move after a bolt as been successfully removed or sufficiently tightened. A powerful work light is also a welcome extra feature, although not essential. The best electric impact wrenches will ultimately provide you with sufficient torque to meet your bolt removal requirements, so don’t skimp on a second-rate power tool with insufficient torque levels.
