A detailed guide of the most common and helpful air tools
Pneumatic tools are powered by compressed air, and they have a wide variety of applications. Here is your ultimate guide to air tool types, use and maintenance.

According to research, DIY projects account for 38% of all home improvement efforts performed annually.

Why are so many people trusting themselves to tackle such efforts as demolition, remodeling, dry-walling and more? Put simply, tools have come a long way.

The same research reveals that American homeowners tackled 43 million home projects themselves from 2015 to 2017. When asked why they decided to do so, 73% said they felt confident in the resources at their disposal.

Are you considering doing some work around the house?

If so, an air tool is a valuable component in your arsenal. Think you’re limited to those oversized jackhammers you see road workers using to drill holes in the street?

Think again.

Today’s air tools, or pneumatic tools, are more compact, handy and versatile than ever before. Today, we’re sharing a few different types and explaining how to use them.

Ready to learn more? Let’s get started!

Advantages of Air Tools

Before we delve into the myriad kinds of air tools available, let’s discuss why you might want to reach for one when it’s time to start your next home project.

First, they’re as useful and practical as the more traditional items you already have in your toolkit. The main difference? Pneumatic tools get their power from an attached air compressor, whereas others are battery-operated or plug into an electrical outlet.

This makeup gives air tools their unique weight-to-power ratio. Compared to a tool with the same power rating, they’re more lightweight. This is because air motors or pistons weigh less than electric motors.

At first, this might not sound like an important feature. Lug around a power tool for hours at a time, however, and you’ll realize how much of a difference weight can make.

Moreover, air tools are simpler and less complicated to operate. Especially for those new to the DIY space, this is a major plus. Other notable advantages of air tools include:

  • The ability to stall them without fear of the Electromotive Force (EMF) dropping, leading to motor burnout
  • A sparkless operation for improved safety around flammable liquids and damp environments
  • Slim design ideal for narrow or cramped work environments
  • Their ability to work in locations that don’t have access to power

Now that we’ve covered a few of their best features, let’s review some of the best air tools around.

31QW60pOWuL Your Ultimate Air Tool Guide: The Different Types and Their Applications1. Air-Powered Drill

When you need a project done quickly, an air-powered drill gets the job done.

Though the most common type of pneumatic drill is the jackhammer, there are smaller, handheld versions designed for everyday use. These are known as air hammers or impact hammers.

Look for one with an ergonomic design on the handle and lightweight, polymer housing. This way, you can use the drill for hours at a time without experiencing arm or hand fatigue caused by excessive vibrations.

You can use air-powered drills all around the interior or exterior of your house, though their most common applications include:

  • Chipping
  • Riveting
  • Cutting
  • Trimming
  • Piercing

Most hammer barrels are made from hardened alloy steel, making them durable and long-lasting. Inside the barrel is a shank chisel that can normally deliver between 2,100 to 3,500 blows or more per minute. A hardened spring retainer holds the chisel and keeps it in place.

You’ll also change the chisel through this mechanism.

Look for one with a stroke length that meets your project requirements. Most are available in 2-and-5/8-inch to 3.0-inch lengths.

When you operate an air hammer, make sure the chisel is always in constant contact with the work surface. Use air tool oil to keep it running and this gear will last years in your garage!

Anyone who’s ever tried to sand a surface by hand knows how aggravating and time-consuming it can be.

This is where a pneumatic finish sander shines. You’ll use one to improve the quality and finish of a surface before you paint it.

How does it work?

A counterweight sits atop the sander itself, oscillating in a 3/16-inch orbital stroke as you operate the tool.

The result is a smooth finish that’s free of the telltale swirls associated with hand-sanding. These are often preferred over electric sanders because you can push them as hard as you need to without worrying about time-consuming and risky motor burnout.

Looking for the most reliable model?

Some come equipped with a built-in regulator. This allows you to adjust the speed of the sander to match the job and material without adjusting the air compressor by hand.

Available pad sizes vary, though most are between five and six inches. Look for one with flexible edges that won’t harm your work surface. It will work with any sanding paper, as long as it’s PSA-backed.

Most pneumatic sanders feature an RPM of between 9,000 and 10,000 though you’ll need to make sure your air compressor is appropriately rated at 4-cubic feet per minute (CFM) or higher to handle the load.

The best models feature an ergonomic handle for all-day comfort.

41ORQM1azTL Your Ultimate Air Tool Guide: The Different Types and Their Applications3. Pneumatic Impact Wrench

The standard pneumatic impact wrench is 1/2 an inch in size. This tool is useful when you’re assembling or removing fasteners and can be an ideal timesaver for automotive work.

Why use a pneumatic model over a handheld or electric one?

The force alone is worth the upgrade. As the wrench turns, it delivers extra torque, impacting the fastener with heavy blows akin to a hammer. Some models go up to 500 foot-pounds of torque or more.

The best part? Most come equipped with ceramic balls inside that help to diffuse the air, aiding in quieter operation.

This power is invaluable when you’re dealing with difficult or damaged fasteners and also makes it easier to remove stubborn ones that have rusted or been painted over.

For versatility, look for pneumatic air wrenches with adjustable speeds so you can add or subtract from the tool’s power without changing the compressor.

One note: Go ahead and buy a corresponding impact socket set when you buy your pneumatic impact wrench.

If yours is a 1/2-inch model, look for one that fits that drive. This will ensure your safety as the operator, as standard sockets can be dangerous when paired with an air-powered wrench.

41fQhd8p4ZL Your Ultimate Air Tool Guide: The Different Types and Their Applications4. Pneumatic Staple Gun

Looking for a fastener that can be used for an impressive number of applications? You need a pneumatic staple gun.

Known for their ability to handle even the toughest jobs, air-powered staple guns are ideal for furniture upholsterers, carpet installers, electricians and construction workers.

Around the house, you can use one to adjust or install siding, repair small furniture and even hang pictures.

They accept a wider range of fasteners than manual or electric staplers and are also lightweight and simple to operate. Most will run on 60 to 100 pounds per square inch (psi).

Pneumatic staple guns are sized between 16-gauge and 22-gauge and will accept T50 staples that are 1/4-inch to 9/16-inch in size as well as brad nails between 1/2-inch to 5/8-inch in length.

You’ll refill it via the magazine, which reloads on the bottom of the tool. Remember to always disconnect your compressor before loading and reloading your staple gun.

To ensure your safety, look for one that features a dual trigger. This way, you can use it all day and never worry about slipping.

You may already have a standard grease gun in your garage or workshop. It’s used for lubrication on a variety of products.

When you need to lubricate a large number of parts quickly, a pneumatic grease gun can get the job done quicker and with less fatigue. From your lawn mower and chainsaw to your car fittings, there are many places around the house that this tool can come in handy.

Some of the models feature the ability to switch into a continuous delivery mode that delivers up to five ounces of grease or more per minute.

However, most offer single-shot capability, delivering around 6,000 psi with an input pressure of between 60 and 120 psi from the air compressor.

You’ll attach the grease gun itself to an included grease hose, most of which are around 30 inches long. Then, you’ll engage it by pulling the top trigger. Look for a model that features an in-line hose swivel, enabling you to lubricate in even the most narrow crevices.

These tools feature an integrated air bleeder valve that’s essential for priming the gun and eliminating any air pockets. When it’s time to reload, tug on the T-pull to add new grease canister.

When you’re first working to loosen a fastener or tighten it up one last time, you should do so by hand. Yet, sometimes space is limited along with access.

An air-powered ratchet wrench is a top choice for this application. Most come equipped with a built-in power regulator that allows you to adjust the speed and power of the ratchet wrench without changing the air compressor.

Most standard pneumatic models are between 3/8-inch and 1/2-inch, delivering between 50 and 130 foot-pounds of torque and between 150 and 290 RPMs. Look for impact drive sockets that correspond to your tool’s measurements.

Top models are also equipped with sealed ratchet heads, which serve to keep the head from spreading, even under the most extreme load.

Some models will allow the air exhaust to rotate all the way around for 360-degree control while others allow you to choose between two positions. If yours has the former design, you can direct exhaust away from where you’re working and enjoy a quieter workspace.

Safety Considerations

Always use mechanic gloves when handling a ratchet wrench, as it can be difficult to maintain control if you over-tighten a fastener.

For this reason, it’s also critical to make sure your air compressor is designed to withstand the CFM that an air-powered ratchet wrench requires. Look for one that has at least 3.6 standard cubic feet per minute at 90 psi.

Other Top Air Tools to Consider

In addition to the air tools listed in detail below, you can find other pneumatic models to meet your repair and installation needs. Let’s take a look at a few.
