Few tools can match the versatility of an air hammer. These handy tools are invaluable for auto work, enabling the user to free frozen nuts, split stubborn joints, or cut off rusted old mufflers. They can speed up the laborious process of chiseling wood or make short work of tile removal by grinding away mortar. Metal shops use air hammers to cut sheet metal or even shape aluminum and steel.

An air hammer consists of a pistol-shaped tool with a barrel between 7 and 12 inches long. These powerful tools use compressed air to fire a piston, engaging a chisel tip that punctures, chips, or grinds through hard materials ranging from stone to metal.

In this guide are factors to consider when shopping so you can discover some of the best air hammer options on the market.

What to Consider When Choosing the Best Air Hammer

Ahead, learn about the most crucial factors to consider when shopping for an air hammer.

Power and Air Compressor

Air hammers, true to their name, use compressed air to power the piston that creates the hammering action. They require about 90 psi (pounds per square inch) of air pressure to fire the piston and at least 4 cfm (cubic feet per minute) of pressurized air to operate continuously.

With that in mind, the size of the air compressor is a significant factor in how well an air hammer will perform. Air hammers will operate with a compressor that produces 4 cfm at 90 psi. While a 4 cfm air compressor is suitable for most home workshops, a 4 cfm air compressor may not produce enough compressed air to meet heavy-duty jobs, forcing the operator to wait periodically as the air compressor recharges.

A large air compressor that can produce 13 cfm at 90 psi will allow an air hammer to run at peak performance, allowing the operator to use it continuously without delays.

Stroke Length and Size

An air hammer’s power directly correlates to the barrel’s length. The barrel houses the piston, which creates the hammer impact. A longer barrel allows for a longer stroke length for each blow the piston makes. That longer length gives the piston more time to reach a higher velocity, resulting in a more powerful blow. Shorter barrel air hammers have a shorter stroke and thus a less powerful impact, but can produce more blows per minute.

A short barrel air hammer is best suited for light-duty jobs that require precision and control, such as cutting through sheet metal or body panels of a car and removing wheel studs. Long barrel air hammers, in comparison, can handle heavy-duty jobs, such as chiseling out corroded nuts, grinding out mortar, or removing a ball joint on a car.


Air hammers include a set of attachments that allow for chiseling, cutting, and shaping metal or mortar. Some air hammers will come in sets with four or five attachments. The chisel shank size determines the type of chisel attachments the air hammer can take. Most air hammers for DIYers feature a chisel shank of 0.401 inches, while pro-level air hammers found in auto shops feature larger chisel shanks of 0.498 inches.

Blows per Minute 

Blows per minute (BPM) delineates how many impacts the hammer can deliver in 60 seconds. An air hammer with a higher BPM will allow for more precision cutting. Shorter barrel air hammers tend to generate more blows per minute because they have shorter stroke lengths. A quality air hammer with a 2⅝-inch barrel might produce 3,500 BPM, whereas a quality long barrel air hammer with a longer 3¾-inch stroke might produce 2,200 BPM.

Size and Weight

Air hammers range in weight from 3 pounds for the lightest and shortest models to 6 pounds for longer barrel models. Air hammers range in size from 7 inches long for short barrel models to 12 inches long for long barrel air hammers.

Shorter air hammers are suitable for use in the small nooks and crannies of cars, helping free up frozen nuts, while longer air hammers provide the power needed to cut through exhaust pipes.

If you’re wondering about an air hammer’s applications or how to operate one safely, then read on for answers to some of the most common questions about using an air hammer.

Q: What is an air hammer used for?

An air hammer is a versatile tool that can be used in many jobs. Metal shops use air hammers to cut or shape sheet metal. Auto shops use air hammers to cut exhaust pipes, free frozen bolts, or separate ball joints. In construction, air hammers are used to break up grout between tiles or remove mortar.

Q: How do I change the air hammer bits?

When changing the bit in an air hammer, remove the air hose first. Remove the spring retainer from the air hose, remove the bit, and insert a new chisel. Lock the chisel in place by reattaching the spring retainer over the bit and turning it clockwise. Make sure the bit is properly installed by pushing and pulling on it.

Q: Are air hammers dangerous?

Like any power tool, air hammers have the potential to cause injury. It’s essential to wear safety glasses when operating an air hammer to protect the eyes from debris. Since air hammers run at 90 decibels, it’s also a good idea to wear ear protection.
