What to Consider When Buying the Best 1-inch Impact Wrench – Buying Guide

As many options are available in the market, buying the best 1-inch air impact wrench is troublesome work. Many hours of research lead us to come up with a few considerations which play a vital role in buying the best one.


1″ air impact wrenches are available in 2 types: air-powered and electrical. Both types come with benefits and drawbacks; let’s look at the 2 types separately.

Air Powered

Generally, air-powered 1″ impact wrenches are heavier. They run by taking the assistance of an air compressor that is attached to them. Also, they create a lot of noise when operating. But air-powered impact wrenches generate more power than their counterparts: electrical ones.

Usually, electrical 1″ impact wrenches are easily portable due to their lightweight nature. As stated earlier, they generate less power compared to air-powered ones. They don’t create much noise and are suitable for light-duty tasks.

IPM Rating

The word “IPM” refers to Impacts Per Minute. So, what does IPM mean? The number of total hits by the hammer on the outer shaft per minute is known as IPM.

It means the tightening speed of a tool kit is determined by Impacts Per Minute. This is a must-have feature that you should look for when buying the best 1-inch impact wrench.

RPM Rating

RPM is another factor that you mustn’t compromise when buying an impact wrench. The word RPM is the short form of Rotation Per Minute that lets you determine the speed when the output shaft spins without load.

You will know the speed of pulling off a nut or installing a bolt through the RPM rating. The higher the RPM rate, the quicker you can finish the job.

Torque Generation and Impact Force

The prime responsibility of impact wrenches is to install or uninstall sockets, bolts, or nuts. They do this by generating the required amount of torque. Dislodging a lug nut will never become an easy task until the impact force defeats the friction and inertia.

In order to make sure that your selected 1-inch hydraulic impact wrench is worth the price, make sure that it has a robust torque generating mechanism. At the same time, it must create maximum torque.

Generally, 1-inch impact wrenches are well-known for creating high power, and they are the best option for heavy-duty jobs.

Construction and Durability

Undoubtedly, repairing work requires precision. In the repairing workshops, repairing tools have to undergo stress as they constantly face heavy pressure. As a result, they can break or get damaged if not constructed with durable materials. To avoid this type of breakage issue, a 1-inch drive air impact wrench gun must feature rugged and robust build quality.

Most 1-inch air impact wrenches are housed with aluminum alloy, giving them durable construction. The best tone should be the perfect combination of power and sturdiness. Simultaneously, it has to be lightweight as well as easy to use.

Comfortable Grip

Since a 1” impact wrench is a handheld tool, fatigue and strain may build up in the arms and shoulders when using this device for a long time. Thus, the efficiency of the task may be reduced. At the same time, the maintenance worker may make mistakes in his job.

That is why manufacturers noted this point and ergonomically designed the grip of the tool. The manufacturer designed the grip in such a way so that the handle offers comfort even when the tool is used for long hours.

Some 1-inch impact wrench handles are well-cushioned or well-padded to give comfort to the user. With these tools, the users can work for long hours without fatigue or strain in hand.
