The Ultimate Guide to Impact Wrench for Automotive Works

impact wrench for automotive work

An impact wrench is a tool that provides high torque output with little effort applied by the user. The device accumulates an amount of energy in the rotating mass and then releases it to the output shaft.

The primary use of impact wrenches is for adjusting, tightening, or removing lug nuts, bolts, screws, axel nuts, suspension components, and similar. Their size may vary according to the use, and they can be for construction, maintenance, or automotive.

A cordless impact wrench for automotive use is the smallest and most compact version of this tool. It is part of its success among DIYs. Frequently, they are a crucial tool for changing wheels and tires. Besides, they are suitable for bikes or boats too.

The Power Source for Impact Wrenches

An impact wrench needs a power source to work. Depending on the model and its use, it may take power from different sources as follows:

The impact wrenches can use any of those sources. But when it comes to cordless impact wrench for automotive, the power source is electrical.  Nowadays, the best options are powered by Lithium-ion batteries that can go from 12 to 24 volts.

Impact Wrench Torque Needed Automotive Works

An impact wrenches’ torque determines performance. With the proper torque, dealing with any tightening or loosening task becomes easy. It will help you avoid the over-tightening issue. All types of impact wrenches come with adjustable torque settings that make them a useful power tool for a wide range of tasks.

The average torque for automotive works of impact wrench is about 1200 ft-lbs. It is more than enough for even the most substantial automotive tasks.

Learning about the maximum and minimum torque level for your car tires is essential. This will help you unscrew over-tightening nuts when you need to change the car tires on the road. The truth is, most people are unaware of the right torque level, and they surpass the required torque level.

Air Impact Wrench for Automotive Work

The Anatomy of a Cordless Impact Wrench for Automotive Use

A cordless impact wrench is always evolving with the arrival of new technologies. That makes them lighter and more user friendly. Despite the differences from one model to another, they maintain the underlying anatomy that functions as follows.

Design

The basic design for cordless impact wrenches may come as inline or like a pistol grip. The inline design looks like a screwdriver and includes a grip behind the hammer. On the other hand, the pistol grip design shows the grasp below the stick.

Along with the design, the wrench’s material is crucial because it determines the resistance and maneuverability. Nowadays, it is common to find them with a rubber hand. This feature makes it anti-slippery.

Lights

Besides the necessary measures, it is recommended to have a set of exchangeable impact sockets. They may start at 10 mm and go up to more than 30 mm. It allows you to work on different areas of the vehicle.

Battery

The batteries have two significant aspects to analyze. Firstly, the voltage which provides the strength to the impact wrench.  Secondly, the size. When the battery is too big, it makes it more challenging to maneuver the tool.

So, it is necessary to think of your limitations when it comes to handling it. Some models include two batteries to increase the power of the impact wrench. The best cordless impact wrench for automotive work can use either small or big batteries. That is because electricity is a combination of motor and battery.

Motor

The motor also contributes to the power of the impact wrench. The newest models include sophisticated brushless versions that reduce the noise and still provide massive torque. The power of the motor is measured in rpm and bpm. When they exceed 200 rpm, they are considered very strong.

Accessories and Miscellaneous

A cordless impact wrench for automotive has plenty of features to provide comfort to the user. They also maximize the power and function. Some of them may include the following:

  • Speed: they start with one or two speeds, and some models may consist of up to 3 speeds
  • Forward/reverse switch: this feature allows loosening and tightening of nuts.
  •  Drill set: it includes sockets of different measures, and many wrenches include this set
