10 Best Adjustable Torque Cordless Impact Wrench 2025 in the United States

The Milwaukee 2967-20 M18 FUEL™ 1/2" High Torque Impact Wrench is a robust tool designed for heavy-duty applications. With an impressive 1,100 ft-lbs of fastening torque and 1,600 ft-lbs of nut-busting torque, it is highly powerful, making it suitable for tough jobs such as automotive repairs and construction tasks. The brushless motor ensures efficiency and longer tool life.

Additionally, the impact wrench features an AUTO SHUT-OFF control which prevents over-tightening by capping the torque at 50 ft-lbs for hand-tight applications, making it user-friendly and reducing the risk of damage to your workpieces. The Bolt Removal Control feature is also a handy addition, providing full torque to loosen bolts and then reducing RPMs to prevent fastener drops, enhancing both safety and convenience during use.

Weighing in at 2.7 kilograms (5.94 pounds) and measuring 7.6 inches in length, it is moderately heavy but manageable, particularly given its power. However, it's worth noting that this impact wrench is sold as a 'tool only' item, meaning the battery and charger are not included and will need to be purchased separately. The tool is part of the M18 system, which is known for reliable performance and compatibility with other M18 batteries. The red metal construction suggests durability, which is crucial for withstanding rigorous use. The weight might be a bit heavy for prolonged use, and the cost could potentially be higher when factoring in the purchase of separate batteries and a charger. The Milwaukee 2967-20 is a powerful and durable tool with useful features for precise work, but ensure to budget for the additional components if you don't already have them.

The DEWALT 20V MAX Cordless Impact Wrench (DCF900B) is a robust tool designed for a wide range of fastening applications. With a maximum fastening torque of 1030 ft-lbs and breakaway torque of 1400 ft-lbs, it's powerful enough for demanding tasks. The 4-mode speed settings and variable speed trigger offer great control, making it versatile for different applications. The Precision Wrench control feature is particularly useful, as it helps prevent overtightening and fastener run-off, which can be a common issue with high-torque tools.

This model also includes an on-tool LED light, which is convenient for working in dark spaces. Additionally, the BATTERYGUARD technology is designed to reduce wear and tear on the battery, though it's worth noting that the battery is sold separately. The tool is relatively heavy at 7 pounds, which might cause fatigue during extended use. However, its ergonomic design can help mitigate this.

The build quality is solid, typical of DEWALT's reputation for durable tools, and it comes with a 3-year limited warranty, 1 year of free service, and a 90-day money-back guarantee, adding to its reliability. One downside is that the battery and charger need to be purchased separately, which can increase the cost. If you're looking for a powerful, versatile, and durable impact wrench, the DEWALT DCF900B is a strong contender, especially if you already own compatible DEWALT 20V MAX batteries.

The Milwaukee 2855-20 18V Brushless Cordless 1/2" Impact Wrench with Friction Ring stands out with its robust Powerstate brushless motor, delivering an impressive 250 feet of breaking torque. This makes it a strong contender for tasks requiring substantial power. The 18V battery provides a decent voltage, supporting sustained operations, although it's important to remember that the wrench does not include the battery, which must be purchased separately.

A key feature is the adjustable torque settings, particularly the automatic shut-off mode that prevents over-tightening, enhancing productivity and protecting fasteners. The bolt removal mode is a thoughtful addition, offering better control by reducing RPM once the bolt is loosened.

With a weight of just 2.4 pounds, it is lightweight and likely comfortable to use over extended periods, benefiting those who prioritize ergonomics. Durability is bolstered by the chrome-plated steel construction, suggesting this tool can withstand regular use in tough environments. LED lights are integrated to improve visibility in low-light conditions, minimizing shadows and making it easier to work accurately.

Potential drawbacks include the need to purchase batteries separately and the fact that it offers 20 foot-pounds of torque—considerably lower than the breaking torque—indicating it may not be suitable for the most demanding heavy-duty applications. Nevertheless, with a customer rating of 4.4 out of 5 stars, it is well-received by users who value its compact and efficient design, making it a great addition for those seeking a balance between performance and ease of use in medium-duty tasks.
