What is an Air Chisel?

Air hammers are power tools that enable their users to chisel stone, cut metal or remove mortar from a wall. They are commonly referred to as air chisels as they can be used to carve and shape stone.

Unlike most power tools they are not powered by electricity, as they need a constant supply of pressurized air to keep the work bit running. Each model is compatible with an array of work bits, such as air hammer bits or chisel bits.

Air hammers also need air compressors to function, and you must check the model’s air consumption in order to determine which type of air compressor you are going to need.

Most air compressors for nail guns are capable of powering an air chisel as you won’t need more than 30 CFM to operate even the high-end models at their maximum capacity.

The most common types of Air Hammers

All air hammers can be divided into two categories, as short barrel models are designed for lightweight applications, while the long barrel air chisels are best suited for use in industrial settings.

Most standard models have short barrels and they are commonly used to cut a thin sheet of metal or remove a wheel stud. On the other hand, the long barrel air chisels don’t have regular shanks and they enable you to work with tough materials.

The level of vibrations these tools produce depends on their type, so if you opt for a long barrel air hammer you will have to deal with strong vibrations while you are using it.

Even so, air chisels are not heavy since they are designed to be held with one arm, and using them for 30 minutes continually is unlikely to cause fatigue.

What can I use the Air Hammer for?

Versatility is a big part of the reason why professionals and hobbyists consider air chisels to be an essential part of their tool kits. Removing frozen nuts, cutting through different types of pipes, or separating tie rods are among the most common applications for which air hammers are utilized.

The scope of tasks you can perform with this power tool depends on the work bits you have, as well as the model’s maximum operating speed and stroke length.

Besides, the shank diameter can limit the range of work bits you can use with a particular air chisel and you must check which ball joint separators, chisels or soothing hammers are compatible with the air chisel you are interested in.

The advantages of Air Chisels

  • Flexibility – Compatibility with a broad array of work bits makes air chisels useful in different contexts. Hence, you can use the same tool to remove mortar from a wall and cut pipes you want to use for your basement improvement idea.
  • Lightweight power tools – Most air chisels weigh less than 6 pounds and they are equipped with handles that ensure you can keep a firm grip of the tool while you’re using it. Despite being lightweight these tools can perform heavy-duty tasks with ease.
  • Reasonably priced – You won’t have to spend a fortune on an air chisel, as even high-end models can be purchased for a few hundred dollars.

The disadvantages of Air Chisels

  • Vibration and noise levels – Although the amount of noise and vibrations an air chisel produces depends on the model, these tools can be difficult to control due to the high vibration levels. In addition, some air chisels make more than 90dB of noise.
  • Safety concerns – There are a number of safety measures you need to take before you start using an air chisel as the debris flying away from the material you are working with can easily end up injuring you.

The most important features of Air Hammers

Several factors can help you narrow down your search for an air hammer that fits your needs perfectly. The tool’s average air consumption, maximum stroke length, or barrel length are among the features that can grant insight into the model’s performance capabilities.

Here are some of the most important features you should pay attention to while selecting an air chisel.

Air Compressor size

The air compressor you are using to power an air chisel must be capable of supplying more PSI and CFM than the tool needs to function normally. For instance, an air hammer that requires 4CFM at 90 PSI cannot be powered by an air compressor that can only provide 70 PSI.

However, most air chisels can be powered with a portable 12V air compressor that is used to inflate tires or run other pneumatic tools. Checking the air chisel’s air volume requirements will help you determine which accessories you need in order to use it normally.

Maximum power output

Besides the tool’s air consumption demands, you should also pay attention to its maximum number of blows per minute. Manufacturers usually include the BPM value in the description of the product, so finding this information shouldn’t be too difficult.

Higher BPM values shorten the amount of time you have to spend performing a task, as an air chisel that offers 4500 BPM is considerably faster than the model that works at a maximum speed of 2000 BPM.

However, the tool’s vibration level increases with the power output, and controlling the tool at high BPM values can be difficult.

Trigger type

Maintaining control over an air chisel may prove to be a challenge, especially if you have no way of managing its power output. Models that are equipped with a progressive trigger allow you to increase the power output gradually and adjust it to the material you’re working with.

Safety is another reason to opt for an air chisel that has a progressive trigger as this feature makes it easier to keep the tool under control at all times.

The length of the barrel

Precision is one of the greatest advantages a short barrel air chisel has to offer. Despite having the ability to operate at 3000 BPI or more, these models are only suited for lightweight applications.

A long barrel air chisel offers a lower stroke rate than the short barrel chisel, but they are capable of handling sturdy materials. Also, a short barrel air hammer usually weighs less than a long barrel air hammer, which makes it more difficult to use them continuously for a long time.

Astro 4980 – The Best Air Hammer

Astro 4980

The fact that Astro 4980 has dual functionality, makes it the best air hammer on the market. Besides utilizing the air chisel function, this tool lets you use its riveter features to fasten loose nuts or bolts.
