What Is an Air Hammer?

An air hammer is a handheld tool that uses pneumatic power to carve into stone, break and shape metal and even wood. The strength comes from pressurized air that transfers energy through a series of repetitive strokes through the barrel.

These tools are so effective, thanks to the transfer of power from the pressurized air tank and the zero loss of PSI. An air hammer can cut through a steel pipe with ease when turned on full.

Air hammers are also useful to those in creative industries. Sculptors use them to chip away at marble and stone to create intricate shapes and designs.

How Do Air Hammers Work?

When the trigger is depressed, the air is supplied from the air compressor to a valve inside the hammer. Inside the barrel, there are pistons as well as two chambers located above and below the moving piston.

The pressurized air pushes the piston down, which moves the hammer action, known as the chisel extension, and this is what causes the chisel to strike the surface of your material.

The piston is forced back to its original position because of the air supply, and the whole process repeats in rapid succession.

What Can You Use an Air Hammer For?

Air hammers are ideal tools for heavy-duty industrial applications like removing old pipework and breaking up concrete. They are also found in fabrication settings where metal and alloys are cut and shaped.

The auto-industry uses them to loosen rusted or stripped bolts and nuts, and separate ball joints and shock absorber nuts, thanks to the vibration from the hammer action. In fact, air hammers are useful in any application that involves home renovations, dismantling machinery, car renovations, and even the arts, like sculptures.

How Do You Choose the Best Air Hammer?

If you’ve decided that an air hammer is the right tool, then you need to know what to look for when making your choice. Here are some simple elements to bear in mind.

Blows Per Minute (BPM)

You’ll hear this term a lot with air hammers and any other tools that have a percussive striking action. The blows per minute do exactly what they say. They are the number of times the piston pushes down to operate the hammer action of the chisel.

The BPM is the number of times this process occurs within a minute. The more BPM, the more powerful the machine, and the better it is at delivering that power. Each model caters to different tasks, and the BPM varies.

If you are a beginner, it might be a good idea to opt for a BPM somewhere in the medium to low range. 2,000 BPM is considered moderate, while 3,000 BPM is medium to heavy-duty. Getting a machine that’s too powerful can render it unusable in the hands of an inexperienced user.

A BPM of between 2,000 and 3,000 should have enough punch to cover 90 percent of all your tasks.

Trigger Control

How the power gets delivered depends on the type of trigger you have. Some offer instant power, and some allow you to control the compressor’s air delivery by graduating the supply based on the pressure you place on the trigger. This increases your control and stops the device from delivering too much power, which is hard to control.

Instant triggers release the full force of the air hammer the moment you press the trigger. While not suitable for all applications, construction workers and those operating within industrial settings appreciate this feature the most. They have little time to waste, waiting for the air hammer to reach capacity, and demand that instant speed.

For safety, a gradual increase of speed is better as it affords better control to the user.

Air Power

The impact of an air hammer comes from the compressor, which delivers a supply of compressed air. The hammer attaches to the compressor with an air hose. Be sure to check the PSI of the compressor and the hammer to make sure they are compatible. The last thing you want is an air hammer that struggles because the compressor is too weak.

While this is less of an issue with modern air compressors, built to match most tool standards, it is worth checking. An air compressor with a PSI of 100 will easily work with an air hammer with a PSI of 80. However, if the hammer has a PSI of 95 percent of the compressor’s maximum PSI, they are unlikely to match.

Barrel Size

A longer barrel delivers more significant amounts of force from the piston to the chisel. Imagine a handheld drill versus a pneumatic drill, and you’ll get the idea. Some of the heavy-duty models, designed for commercial use, have long barrels for this very reason.

This makes them powerful, but far less user-friendly or portable and less versatile. It also adds to the weight of the device. If you are looking for an all-around air hammer, don’t consider a model with a long barrel.

The most common is a medium-sized barrel. It will cover most of your tasks with ease. If you opt for a short barrel, expect the tool to be less potent, but the upside is it gets you into hard-to-reach places.

Does It Have a Chisel Set?

In the hands of an experienced operator, one chisel will cater to most tasks. However, if you want real versatility, getting a chisel set increases the applications. Chisel sets typically come in packs of 3 or 5, with different widths and surfaces.

Air Hammer Safety Tips

As with all tools, there are safe ways to use them. Here are a few hints and tips to keep you free from injuries.

Check the Compressor

Since all the power comes from the compressed air in the compressor, it is a good idea to make sure it isn’t empty. Waiting while the tank refills is a waste of time and could cost you money. Also, if you try the air hammer without the correct PSI, it could lead to damage to the tool and injury.

Choose the Right Chisel

Choosing the right attachment for the job is fundamental. Each chisel has a different width and surface, designed for each application. Also, make sure you have the right chisel for the material you are working with.

Mismatched attachments could lead to a poor end result and possible damage to the air hammer and the chisel.

Don’t Forget To Lubricate

Add machine oil to the base of the chisel as you insert it into the device. This helps to reduce any damage internally and preserves the chisel attachment.

Unattended Air Hammer

When leaving the air hammer unattended, shut off the air supply and make sure that you relieve the pressure when removing the air hose.

Take a Break

Using an air hammer is hard on your hands, wrists, and arms. To avoid fatigue, take regular breaks, and only work in short bursts.

Don’t Forget PPE

Using any type of power tool can be dangerous, especially if you don’t wear the correct protective equipment. You should put on goggles and ear defenders to protect you from possible flying debris and the noise of the air hammer. These tools are extremely loud!


Hammer the Point Home

Air hammers are useful tools. Whether you are working on your car, stripping machinery on the farm, or producing the next great sculptural art piece, an air hammer is going to make your life easier.

They cut, strip, chisel, remove rivets, and chip away at stone, marble, and concrete. They are the ultimate all-rounder and a tool you should have in your arsenal.
