How To Use An Impact Wrench Like A Pro

So you have decided to buy an impact wrench and want to know more about it! “How to use an impact wrench?” is a very standard question we receive from our readers every now and then. So in this guide I am going to explain the process of usage in brief and also mention some precautions that need to be taken while use.

Why Use an Impact Wrench?

Unlike standard torque wrenches, impact wrenches are easy to use and can get tight nuts loosened pretty fast. With a variety of use techniques, impact wrenches can be air driven or motor operated.

Air impact wrenches, depending on the model, require a 90-120 PSI compressed air supply from a standard air compressor. Whereas motor operated wrenches can either be powered by a battery or a direct electric connection.

Each type has its own advantages and disadvantages. If you are confused about the type of impact wrench you require, you can read the guide given below and decide with ease.

How to Use an Air Impact Wrench?

Air impact wrenches are one of the most trusted impact tools in the market today. Repetitive, tedious tasks like changing vehicle tires can really take a lot of time, being added up during the course of the day, hampering your profit margins. As a result impact wrenches are extensively used in car repair workshops and assembly lines.

The steps of using an air impact wrench are given below.

1. Unpack and Assembly

Looking like an old drill, most air impact wrenches have a metal body with a rubber cover. A trigger release switch helps you start and stop the impact wrench as per the requirement. A long rubber hose connects the air impact wrench with an air supply unit/air compressor. This hose supplies the required air pressure to the impact wrench.

Unpack your unit, most internal parts will come assembled. You will just need to attach the air supply using the hose. Connect the hose first with the air compressor and then to the air impact wrench. Use quick release clips on the impact wrench end, so that you can disassemble the impact wrench at any time as per the requirement.

2. Testing Time

Do check about how many psi your impact wrench requires. Without the right level of air pressure, your air impact wrench will not give its best performance. PSI stands for pounds per square inch. Ideally 90-120 PSI air supply is required by most air impact wrenches depending on the model.

Do a quick check of the hose line and the attachments. The hose must be straightened to facilitate proper, uninterrupted air supply. Remove twists and kinks in the hose to ensure sufficient air supply to the tool.

Most impact wrenches can do forward as well as reverse rotations. Check the direction of revs by lightly pressing the trigger. If that is not the direction you want, you can reverse the direction using a switch or latch present on the side of the tool.

Tightening requires clockwise rotations and loosening requires anti-clockwise rotations. Make sure you have the settings right.

3. Speed Setting

Different tasks have different speed requirements. You need to set the speed right to get the right results. There must be a switch or dial on the body of the impact wrench for speed control. Next important thing is the usage of right size socket.

How to Use a Cordless Impact Wrench

They may be on the costlier side but their portability is something you will need quite often. Best cordless impact wrenches now come with the same power specifications as the air impact ones and therefore are sure to dominate the market in the near future.

Charge your 18V or 20V battery using the right charger. After it is fully charged attach it with the impact wrench and you are ready to run.

The check points of rotation direction testing and torque adjustment remains the same as mentioned in the air impact wrench category.

What Sockets to Use with Impact Wrench

There are two types of sockets available in the market for use with impact wrenches: Impact sockets and regular sockets.

The sockets need to withstand huge amounts of vibration and shock during rigorous usage. This vibration results in most regular sockets crack under pressure. Unlike regular sockets which are made of chrome vanadium steel, impact sockets are made of chrome molybdenum steel, having more strength. The impact sockets can withstand shocks better and thus have longer lives.

Impact sockets are also black in color, as you may observe them in an assembly line. This black color is due to a black oxide coating which prevents it from rusting.

Impact sockets are the best choice which there is prolonged usage such as in a workshop or assembly environment.
