Types of an Impact gun

Impact guns are divided into two categories based on the type of motor they use to produce torque. One is an air-powered impact gun and the other is an electric-powered impact gun. Electric-powered impact guns are categorized into corded impact guns and cordless impact guns.

Air-Powered Impact Gun

Air impact gun is also known as pneumatic impact gun. This impact gun uses compressed air to rotate the motor. Air impact guns require an air compressor that continuously supplies them with compressed air. The most powerful 1/2 air impact gun  come in a range of drive sizes from 0.25 inches to 1 inch. The drive size describes the amount of torque that a tool can produce. Air impact gun with ½ inch drive size generally used.

  • Can be used constantly.
  • Smaller in size as compared to other electric-powered impact guns
  • Perfect to use in small spaces.
  • No power adjustment system.
  • This makes it difficult when less power is supplied.
  • When just a little torque is needed, an air impact gun may produce excessive power will end up breaking the bolt.

Corded Electric Impact Gun

These impact guns use an electric motor. They have a cord used to connect them to a power source. Corded electric power impact guns are now quite rare since manufacturers are now shifting towards cordless ones, they still be found. They typically have longer bodies than pneumatic wrenches, the extra length added by an electric motor which produces the torque.

  • The force is adjustable to a required level.
  • Electric impact guns do not need a compressor to operate.
  • Cannot operate in areas where electricity is not present.
  • Limited range of wire.
  • Need power source with the length of wire.

Cordless Electric Impact Gun

Cordless electric impact guns use rechargeable batteries. Batteries are available in different volts from

  • 12 to 20 volts

This depends on the model of the impact gun.

  • Cordless electric impact guns are portable require no external power source.
  • Convenience and flexibility at construction sites where electricity is not available.
  • Cordless electric impact guns are less powerful as compared to corded and air-powered impact guns.
  • Batteries can’t store enough power to produce a high ratio of torque.
  • Need charging often.

How an Impact Gun Works?

An impact gun resembles the shape of a real gun. It has a grip and a trigger, a rotating hammer and a motor. The motor rotates the hammer at a high speed. The rotation produces kinetic energy stored in the hammer. It applies this stored energy in a short burst which results in a powerful torque delivered on the nut.

The torque level of the impact gun can be controlled by a knob that has multiple settings. These settings are helpful in attaining potent results without giving stress to the arm. Impact guns are mainly of three types depending on the factor of power source.

If you are willing to buy for your convenience—the best consideration depends on your easiness, choosing the model with a cordless system will free you from the menace of cords. Nevertheless, this will give you the hectic of changing or charging the battery. On the siding hand, the corded will have a mess of wire and needed to be used limited by the wire length with socket position.

Features for the Most Powerful Air Impact Gun

A perfectly working tool for one person doesn’t mean it will work the same way for you as every person have different needs and requirements.

Size of the Drive

There is also a need to choose the right size of a drive that your impact gun would require. Most buyers believe that the bigger the size, the better. However, this is not always the case. You don’t need a one-inch impact wrench to loosen a bolt as small as 10-mm. On the other hand, it should not be any less in ratio to the required power.

Torque Adjustment

It allows you to control the output power of the gun. If you apply force more than the torque required, there is a chance that you will shatter the nut.


The most important feature to consider while buying an impact gun is torque. It is the output power applied to the bolting and unbolting action. Torque is measured Newton-meters. Many buyers make the mistake that they underestimate the force they need. When you have different uses, you have to find the recommended torque rating and add some margin. It is advisable to look past the torque numbers advertised by the manufacturer and calculate what works for you.

Size of the Gun

Typically, the smaller, the better, however, there is a tradeoff between size and torque. Smaller size allows you to use your gun in tighter spaces, but you will sacrifice a little torque. We usually find that it’s best to balance these two features.

Balance and Ergonomics

Factors related to user safety and ergonomics are of much consideration like vibration and noise level. Tools made with composite materials are user-friendly and produce less noise as compared to the tools made by metals.
