Buyer’s Guide

Price, product construction, durability, and reliability are important criteria for a review of best air impact wrenches. The best rated tools put out significant torque, and their casings are durable enough to withstand blows and hard knocks and protect the internal workings of the tool. A standard half-inch drive is sufficient for heavy workloads.

Types

Air impact wrenches may be:

• air-powered,
• electric
• battery-powered (cordless).

Air-powered impact wrenches must have an air source (compressed air) to operate. Electric impact wrenches must be plugged into an outlet. Battery-powered, or cordless, impact wrenches have charging stations and rechargeable batteries. Professional mechanics and industry typically use air- or electric-powered air impact wrenches. The home mechanic may find a battery-powered air impact wrench is more convenient and quiet.

Air impact wrenches are easy to use and provide significant power and torque when connected to an air compressor. The cost to buy an air impact wrench has significantly decreased, making purchasing one of these tools a viable solution and makes professional, industrial, hobby, or DIY automotive and other applications more efficient. Air impact wrenches are designed to remove or install bolts and nuts faster and more easily. They also provide more leverage than a manual wrench, thus increasing overall productivity. Safety and accuracy features have also improved.

The primary drawback of using an air impact wrench is the risk of securing the bolts too tightly. Over-tightening can result in stripped threads or reduced bolted joint integrity. Applying too much torque can also twist off the bolt head, which will then necessitate drilling out the bolt. Cross-threading is also common. It is recommended to start the bolt manually then finish driving it with the impact wrench.

What to Look for When Buying an Air Impact Wrench

Air impact wrenches generally have similar features with minor exceptions or patented technology specific to the brand. There are many things to consider when buying, although the primary considerations should be:

• the torque needed for your particular application
• your air source (size of compressor and air hose reel).

Decide what type of work you need the impact wrench to do. This determines the power source, and the weight and size of the tool (and sockets). Smaller jobs, for example, may only require a model that holds ¼” sockets. Larger projects may need a wrench that holds 3.5” sockets.

Ensure you do not underestimate the amount of torque you need for your particular job/application. Also ensure your air source meets the airflow requirements and you have the correct accessories. Air impact wrench tool, power source, and accessory requirements are usually found in the operator’s manual provided by the tool’s manufacturer or distributor.

• Power / Torque: The air impact wrench’s torque is the amount of power it can produce. It is necessary to have adequate torque to remove/install a fastener (nut or bolt). The more torque the tool produces, the easier the application should be. A standard (medium-duty) air impact wrench is a good choice for a variety of different undertakings. Higher torque (min. 150 ft. lbs.) provides more power and is typically used by professional mechanics, automotive teams, etc. The torque may also be affected by the size of the air compressor you use. An air impact wrench that has power settings that allow torque adjustment can help reduce the risk of over-tightening a bolt or twisting off a bolt head.
• Compressor/Tank Size: Compressor tank size, motor horsepower (hp), air volume output (CFM), and air pressure (psi) must be sufficient to operate the particular air impact wrench. The volume of air the compressor produces (CFM) and the air pressure contained in the tank (psi) are the most important considerations and they can impact the tool’s power and performance. These specifications are typically marked on the tank’s label.
• Impact Wrench Weight / Size: Air impact wrenches that are heavier may be fine for small/short projects. Heavier impact wrenches can cause wrist/hand stress and fatigue faster when working on a larger project. A heavier wrench will become more difficult to control as a result. Smaller, more compact and lighter weight wrenches also allow you to get into tighter spaces.
• No-Load Speed: The speed (revolutions) the air impact wrench turns (when there is no load) is its no-load speed. Faster/higher speeds secure fasteners faster, although torque is sacrificed. The air impact wrench with a higher torque, rather than speed, is your better choice.
• Impact per Minute (BPM): The hammer mechanism of the air impact wrench allows the hammer to freely spin, impact the anvil, release, and freely spin again. The impact wrench’s impacts per minute tell you how many times the hammer strikes the anvil in one minute. The higher the BPM, the faster the air impact wrench can drive the fastener or loosen the bolt.

• Driver Size: Standard impact wrench driver sizes range from ¼” to ½” or larger. The most common driver sizes for professional and DIY/hobbyist automotive applications are ½” (most popular) and ⅜″. A one-half inch drive suffices for most applications. Three-eighths inch typically comes with impact wrenches that have less torque.
• Handle and Grip: Air wrenches commonly feature ergonomic, rubberized handles that absorb some of the high torque vibration. They should have a comfortable grip and be well-balanced to ensure stress and fatigue are reduced during use. Many air impact wrenches have smaller, pistol grip handles that are easier to hold and control. Pistol grip handles are designed shorter to allow better access into tighter spaces. Progressive triggers also tend to be more controllable and safer to use.

Conclusion

Determine the size of your project. Although most air impact wrenches offer similar features, do your review research to decide which brand, type, and model is the best one for your particular project or application.

The Ingersoll Rand 2235QTIMAX ½” titanium model is a powerful, easy-to-use, quiet, air impact wrench. It is considered the best ½” air impact wrench on the market. It features MAX power, reliability, noise reduction, and enhanced control, and provides the best power-to-weight ratio in its class.

It stands out as our top rated pick, as well as the choice of NASCAR racing teams and hobbyists alike.

There are brands like Ingersoll Rand and Chicago Pneumatic that have been in business a half-century or longer. Reviews have consistently rated them in the top five of top rated air impact wrenches lists.

Remember that the least expensive air impact wrench may not be as sturdy, durable, reliable, offer the best warranty, or have features that simplify use (i.e. adjustable power and speed settings). Conversely, the most expensive tool may be well-made, but heavy, long/unable to fit into tight spaces, or difficult to control.
