The Milwaukee 2967-20 M18 FUEL™ 1/2" High Torque Impact Wrench is a robust tool designed for heavy-duty use. Its standout feature is the brushless motor which delivers impressive torque, up to 1,100 ft-lbs for fastening and 1,600 ft-lbs for nut-busting, making it suitable for demanding applications. The inclusion of a friction ring enhances the ease of socket changes, which is convenient during intense work sessions.

Additionally, the AUTO SHUT-OFF control ensures that hand-tight fastening applications are completed without overtightening, and the Bolt Removal Control helps prevent fastener drops by decreasing RPMs once a bolt is loosened, adding to user safety and efficiency. The wrench operates at 18 volts, relying on battery power, which offers the flexibility of cordless operation but requires purchasing batteries separately as they are not included in the tool-only package. Weighing 2.7 kilograms (5.94 pounds), it strikes a balance between being heavy enough for stable operation and manageable for extended use, though some users might find it slightly heavy for prolonged use.

The ergonomic design aids in user comfort. Made of durable metal, this wrench is built to withstand tough working conditions, enhancing its longevity. However, its size (7.6 inches in length) might be cumbersome in tight spaces. The product has received excellent customer reviews with a 4.7-star rating from 717 ratings, indicating high user satisfaction. If you need a reliable, high-torque impact wrench for heavy-duty tasks, this tool is a solid choice, though be prepared for its weight and the additional cost of batteries.

Torque
Power Source
Weight and Ergonomics

Most important from
4670 reviews

Torque
Delivers exceptional torque that easily handles tough bolts others struggle with, making heavy suspension and assembly work straightforward.
Power Source
Efficient even when powered by smaller onboard air compressors, maintaining high performance without needing a large shop compressor.
Weight and Ergonomics
Lightweight and compact design significantly reduces fatigue during prolonged use, improving overall handling and control.
Durability
Durable construction with titanium hammer case and steel wear plate ensures the tool withstands tough job site conditions and frequent drops.

The Ingersoll Rand 2235TiMAX is a powerful air impact wrench delivering up to 1,350 foot-pounds of torque, making it well-suited for demanding tasks like heavy assembly, suspension work, and industrial repairs. Its 1/2-inch drive size is standard for many automotive and construction jobs, providing good versatility. Being air-powered, it requires an air compressor, which is typical for high-torque impact wrenches but means it’s less portable than battery-operated models.

The tool is lightweight at just 4.6 pounds and compact, which helps reduce fatigue during extended use and makes handling easier. Its titanium hammer case and steel wear plate add durability, allowing it to withstand tough job site conditions and repeated drops, so it should last a long time with proper care. The four-position power regulator and one-handed forward/reverse button give good control over torque and direction, making adjustments simple while working. However, it produces a fairly loud noise at around 103 dB, so hearing protection is recommended.

If you have access to an air compressor and need a durable, high-torque wrench for tough jobs, this model offers excellent performance with solid build quality. It may not be ideal for users seeking cordless convenience or quieter operation.

Buying Guide for the Best Highest Torque Impact Wrench

Choosing the right impact wrench can make a significant difference in your work efficiency and ease. Impact wrenches are powerful tools used to tighten or loosen bolts and nuts with high torque. When selecting an impact wrench, it's important to consider several key specifications to ensure you get the best fit for your needs. Understanding these specs will help you make an informed decision and choose a tool that matches your requirements.
TorqueTorque is the measure of the twisting force that the impact wrench can apply. This is crucial because higher torque means the wrench can handle tougher jobs, such as loosening stubborn bolts or working with heavy machinery. Torque is usually measured in foot-pounds (ft-lbs) or Newton-meters (Nm). For light-duty tasks, a torque rating of 100-200 ft-lbs may be sufficient. For automotive work, 200-400 ft-lbs is typically ideal. For heavy-duty industrial applications, you might need 400 ft-lbs or more. Consider the type of work you'll be doing to determine the appropriate torque level.
Drive SizeThe drive size refers to the diameter of the anvil where sockets are attached. Common sizes include 1/4-inch, 3/8-inch, 1/2-inch, 3/4-inch, and 1-inch. Smaller drive sizes (1/4-inch and 3/8-inch) are suitable for lighter tasks and tighter spaces, while larger sizes (1/2-inch and above) are better for heavy-duty applications. Choose a drive size that matches the sockets you already have or the type of work you plan to do.
Power SourceImpact wrenches can be powered by electricity (corded or cordless), air (pneumatic), or hydraulics. Corded electric wrenches offer consistent power but require an outlet. Cordless models provide mobility and convenience but depend on battery life. Pneumatic wrenches are powerful and commonly used in professional settings but require an air compressor. Hydraulic wrenches are used for very heavy-duty applications. Consider where and how you'll be using the wrench to choose the best power source for your needs.
SpeedSpeed, measured in revolutions per minute (RPM), indicates how fast the wrench can turn. Higher speeds can make quick work of tasks but may be harder to control. Lower speeds offer more precision. For general use, a speed range of 2,000-3,000 RPM is common. If you need more control for delicate tasks, look for models with adjustable speed settings.
Weight and ErgonomicsThe weight and design of the impact wrench affect how comfortable it is to use, especially for extended periods. Lighter models are easier to handle and reduce fatigue, while heavier models may offer more stability and power. Ergonomic designs with comfortable grips and balanced weight distribution can make a big difference in usability. Consider how long you'll be using the wrench and choose a model that feels comfortable in your hands.
DurabilityDurability is important to ensure your impact wrench can withstand regular use and tough conditions. Look for models made from high-quality materials like steel or reinforced composites. Check for features like impact-resistant housing and robust internal components. 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.
