What Are Impact Wrenches Used For?

Different sockets allow the handheld tool to perform a variety of tasks including the following:

  • Used to put up garden decking
  • To remove bolts from wheels when changing tires
  • Tightening and Loosening lug nuts
  • Loosening rusted screws and fasteners
  • Removing a variety of screws

What is the Best Impact Wrench For Your Needs?

Choosing between air-powered, battery-powered, and electrically-powered impact wrenches will depend solely on your profession and the need you have for it. Professional mechanics and technicians prefer air-powered impact wrenches because they tend to be lighter in weight. As well as being more powerful and running longer than battery and electrically-powered wrenches.

An electrical or battery-powered wrench provides enough power for homeowners who would like to complete a few DIY tasks at home. As it doesn’t need an air compressor, it’s much easier to move it around from room to room while charging it in between projects.

Most impact wrenches come with different interchangeable sockets which allows the operator to screw and unscrew a variation of different sized bolts, screws, and nuts.

What’s The Difference Between an Impact Wrench and a Power Drill?

Both an impact drill and a power drill are great tools to have for DIY projects. Although both of them truly are effective in screwing and unscrewing, there is a bit of a difference in the way that they function.

The biggest difference between the two is that an impact wrench uses a hammering force while rotating. This hammering effect doesn’t only creates impact downwards but also sideways. This special impact effect creates a smoother and much more powerful motion.

Hammering from an impact wrench happens hundreds of times within a minute, creating pressure onto the screws and bolts.

When you use a power drill, the operator has to apply pressure to make sure the screw and drill bit is kept in place.

Impact wrenches prevent screws, bolts, and nuts to slip off of the attached sockets. Creating a much easier fastening and loosening action.

Types of Impact Wrenches

There are three main types of impact wrenches. Pneumatic, Electrical, and Cordless impact wrenches. Depending on the kind of project you are working on, you will decide which impact wrench you need.

Pneumatic Impact Wrench

The pneumatic impact wrench is powered by air.  Airflow that is produced by an air compressor creates a very strong output. The air impact wrench is mostly used among professional mechanics and technicians.

It’s popular amongst these professions, because of its longevity. Impact wrenches powered by other batteries or electricity runs out of power quite soon. Whereas an air impact wrench creates a longer working mode. Especially if you use large compressors that functions between 5-7.5 HP.

They can create up to 1,100 foot-pounds of torque.

Electric Impact Wrench

A simple plug-in-socket is the way an electrical impact wrench works. Generally not as strong as an air impact wrench, it can still get difficult jobs done in a jiffy. The only downside to an electric impact wrench would be that the cord might affect the maneuverability with the tool.

Considering the length of the cord is important when buying an electrically driven impact wrench. But one can also buy an additional extension cord.

Cordless Impact Wrench

Without having to drag along a heavy air compressor or a long extension cord, you can use an impact wrench that is powered by a battery. Once the power from the battery runs out, you can replace it with a fully charged one.

Being cordless, it creates excellent maneuverability and portability. You can literally use it anywhere. Especially popular under race car drivers, and motorists, because it can be kept and charged in the car.

How to Maintain an Impact Wrench

Just like any other household power tool, it’s important that you take good care of your impact wrench. Doing regular maintenance on this expensive tool will prolong its life. As well as ensure it works to its optimum capacity.

Here are a few tips you can follow in maintaining your impact wrench.

  • Don’t use the wrong sockets with your impact wrench. Avoid forcing bits from different wrench brands into yours. This will cause breakage and can result in serious injury.
  • Carry your power tool by the handle.
  • Make sure that cords aren’t worn or torn.
  • Switch off the impact wrench after using.
  • Keep your impact wrench clean. Wipe dirt from accessories to avoid the parts breaking, jamming, or misaligning.
  • Use Impact wrench grease to lubricate different parts of the apparatus.
  • Store the tool in a clean dry place within a tool cover.
  •  Don’t apply too much extra pressure while the impact wrench is running. This will damage sockets and studs.
  • Use tool oil to keep moving parts lubricated.
  • Do regular maintenance by checking the torque output when turning both ways.

Key Features to Look Out For in an Impact Wrench

Torque

The most vital feature regarding an impact wrench is the amount of torque it produces. Torque is the description used in which force that causes an object to rotate, is measured. Impact wrenches have a variety of different torque settings, this makes an impact wrench much more versatile for different kinds of jobs.

It’s a very powerful movement that can cause parts to break. That is why it’s important to consider the quality of the power tool in order for it to function using a great torque. Torque is measured in feet per pound. Typical impact wrenches use 300 ft/lbs.

Impacts Per Minute (IPM)

Evidently, the impact wrench needs a lot of powerful push and force to bolt and screw. Consider how many impacts per minute your power tool can create. The more IPMs the more force will be used to push down bolts and screws.

The average IPM in an impact wrench can vary between 0-4000 IPM.

Drive Size

A standard drive size is a 0.5-inch drive. You can also find drive shafts that are much smaller measuring 3/8 inches and 0.25-inches.

Power Supply

As mentioned earlier, there are three types of power supply. Air, Battery, and Electronically powered. The most powerful power supply is that of pneumatic which uses an air compressor.

Battery Life

When you opt for a cordless battery-powered device, then you have to consider the kind of battery it uses. The quality of the battery does affect the power of the torque output.

There are three common battery types used in impact wrenches: NiCad, Li-Ion, and NiMH.

Nickel Metal Hydride (NiMH) – Even though they are the oldest battery of the three, it is extremely affordable and durable. Its low price tag is because it doesn’t function quite as well as the other two battery types.

Lithium-Ion (Li-Ion) – Definitely the best battery type between the three. And they have the price tag to match. An expensive battery with a very long lifespan. They aren’t subject to any charging problems. They do have one default: during the charging process the batteries heat up and this can cause deterioration.

Nickel Cadmium (NiCad) – Even though the NiCad battery is susceptible to charging issues and has to be handled with care, it still provides users with a long battery life.

Weight

Because the impact wrench is a handheld power tool, it’s important to consider its weight when purchasing it. A lightweight impact wrench will be easier to carry around as well as using it for an extended amount of time.

Impact wrenches vary greatly in weight- depending on the brand, model and power supply. They can weigh anything from 5kg-17kg.

Comfort of Use

Going hand-in-hand with the weight of the power tool. You should also prioritize the overall maneuverability of the device. A lighter tool is easier to use and an operator won’t fall to the risk of injury after extended use.

Also, consider the ease of replacing the batteries, sockets, and other accessories. As well as the placement of the power cord. It should be easy to grip and therefore, a rubber handle is perfect for comfortable use.

Settings

There are a few different settings that impact wrenches can have. Adjustable settings can include: tool pressure, air regulator, line pressure, IPM, speed, and torque.

Extras

Safety Features – Powertools can be dangerous. It’s important for users to consider safety features. Things like a built-in cooling system, safety mechanisms, and anti-overloading features.

Accessories – Getting a few extra things with your impact wrench is always nice. A variety of socket sizes, extra battery chargers, and holders, as well as a durable wrench case, are great extras.
