Torque
This tool is unbelievably powerful, easily removing stubborn bolts and lug nuts without delay.
Weight
Despite its compact size, it feels heavy, almost like holding a gold brick, but the power it delivers is worth it.
Build Quality and Durability
Durability is impressive, even after accidentally dropping it in a bucket of transmission fluid, it still works perfectly.

The Milwaukee 2967-20 M18 FUEL 1/2" High Torque Impact Wrench w/ Friction Ring is a powerful tool designed for heavy-duty applications. One of its most impressive features is the brushless motor that delivers up to 1,100 ft-lbs of fastening torque and 1,600 ft-lbs of nut-busting torque, making it highly effective for tough jobs. The 1/2" drive size is standard and versatile, fitting a wide range of sockets. Since this is a battery-operated model, air consumption isn't a factor, which can be a plus if you're looking to avoid dealing with air compressors and hoses.

However, it's important to note that this tool does not include the battery, so you will need to purchase that separately if you don't already own one compatible with Milwaukee's M18 battery system. Weighing in at 2.7 kilograms (approximately 5.94 pounds), it is relatively lightweight for its class, offering better maneuverability and less user fatigue during prolonged use. The AUTO SHUT-OFF control is a nice feature for preventing overtightening, especially useful in more precise applications. Additionally, Mode 4’s Bolt Removal Control is very handy, as it reduces RPMs once a bolt is loosened to minimize fastener drops.

In terms of build quality, the use of metal material ensures durability and long-term reliability. This tool would be an excellent choice for professionals who require a robust and dependable impact wrench for heavy-duty fastening and bolt removal tasks.

Torque
The torque is incredible – it easily removed a rusty rear bumper from a Tacoma.
Build Quality and Durability
After two years of weekly use, this Milwaukee impact wrench still works as good as new.

The Milwaukee 2767-20 M18 FUEL High Torque 1/2" Impact Wrench is a robust tool with impressive torque, delivering up to 1000 foot-pounds. This makes it highly effective for heavy-duty tasks, ideal for mechanics or DIY enthusiasts needing powerful torque. It features a 1/2" drive size, which is versatile for most automotive and industrial applications. Being battery-powered rather than pneumatic, there's no air consumption, which is convenient as it eliminates the need for a compressor, though it may not suit those specifically needing pneumatic tools.

At 6 pounds, it's relatively lightweight, providing good maneuverability and reducing fatigue during prolonged use. The rubber overmold material enhances grip and comfort, adding to its user-friendly design. However, as a bare tool, it doesn't come with a battery, which is an additional cost and consideration for potential buyers.

Noise level isn't specified, but battery-powered tools are generally quieter than their pneumatic counterparts, which might benefit those working in noise-sensitive environments. The build quality is robust, consistent with Milwaukee's reputation for durable tools. The friction ring design simplifies socket changes, increasing efficiency while working. While this wrench ranks high in customer satisfaction, it is not a pneumatic impact wrench, as it uses battery power instead. It's a top choice for those seeking a cordless, high-torque tool but might not fit users specifically needing pneumatic operation.

Build Quality and Durability
The quality of this impact gun is fantastic, and it’s the most powerful and intuitive impact gun ever used.

The DEWALT 20V MAX Cordless Impact Wrench is a high-performing tool that shines in its class of cordless impact wrenches. It boasts an impressive maximum fastening torque of 1200 ft-lbs and a maximum breakaway torque of 1750 ft-lbs, making it suitable for heavy-duty applications such as large pipe flanges and wheel lugs. This high torque capability is one of its major strengths, allowing it to handle tough jobs with ease.

With a drive size of 1/2", it fits a standard category of sockets, which adds to its versatility. The wrench offers three-speed settings and a precision wrench mode, which are beneficial for preventing overtightening and ensuring control over various tasks. An added LED work light enhances its usability by providing illumination in poorly lit areas, which is a thoughtful addition for those working in dimly lit environments.

However, as a bare tool, this product does not come with a battery or charger, which means you will need to purchase these separately if you don't have compatible DEWALT batteries. At 8.4 pounds, it is on the heavier side for a cordless model, which might be a consideration for users who need to use the tool for extended periods. Build quality appears to be solid with a powder-coated finish, contributing to durability, which is a crucial factor for long-term use. The tool's high performance and robust features make it a top choice for professionals; however, the additional costs for batteries and its weight could be drawbacks for some users. It's a reliable choice for those needing a powerful and versatile impact wrench, particularly in construction or automotive repair environments.

Buying Guide for the Best Pneumatic Impact Wrench

Choosing the right pneumatic impact wrench can make a significant difference in your work efficiency and ease. These tools are essential for tasks that require high torque output, such as automotive repair, heavy equipment maintenance, and construction projects. To find the best fit for your needs, it's important to understand the key specifications and how they relate to your specific requirements.
TorqueTorque is the rotational force that the impact wrench can apply. This is crucial because it determines the tool's ability to loosen or tighten bolts and nuts. Torque is measured in foot-pounds (ft-lbs) or Newton-meters (Nm). For light-duty tasks, such as small automotive repairs, a torque range of 100-200 ft-lbs may be sufficient. For more demanding tasks, like heavy machinery maintenance, you might need a wrench with 600 ft-lbs or more. Consider the types of jobs you'll be doing most frequently to choose the appropriate torque level.
Drive SizeThe drive size refers to the size of the square drive that holds the socket. Common sizes include 1/4-inch, 3/8-inch, 1/2-inch, 3/4-inch, and 1-inch. The drive size you need depends on the size of the fasteners you'll be working with. For general automotive work, a 1/2-inch drive is typically sufficient. For larger industrial applications, you might need a 3/4-inch or 1-inch drive. Match the drive size to the sockets you already have or plan to use.
Air ConsumptionAir consumption is the amount of compressed air the tool uses, measured in cubic feet per minute (CFM). This is important because it determines the compatibility with your air compressor. If the air consumption of the wrench exceeds the output of your compressor, the tool will not perform efficiently. Light-duty wrenches may require around 3-4 CFM, while heavy-duty models can require 8 CFM or more. Ensure your air compressor can meet or exceed the air consumption requirements of the impact wrench.
WeightThe weight of the impact wrench affects how comfortable it is to use, especially for extended periods. Lighter models, typically under 5 pounds, are easier to handle and reduce user fatigue, making them ideal for repetitive tasks. Heavier models, which can weigh over 10 pounds, may offer more power but can be tiring to use for long durations. Consider the balance between power and comfort based on how long and how often you'll be using the tool.
Noise LevelNoise level is measured in decibels (dB) and indicates how loud the tool is during operation. High noise levels can be harmful to your hearing and may require the use of ear protection. Impact wrenches can range from 85 dB to over 100 dB. If you work in a noise-sensitive environment or want to reduce hearing damage, look for models with lower noise levels or built-in noise reduction features.
Build Quality and DurabilityThe build quality and durability of an impact wrench determine its lifespan and reliability. Look for models made from high-quality materials like steel or aluminum, which can withstand heavy use and harsh conditions. Features like a robust housing, reinforced anvil, and quality internal components contribute to the tool's longevity. If you plan to use the wrench frequently or in demanding environments, investing in a durable model will save you money and hassle in the long run.
