10 Best Highest Torque Impact Wrench 2026 in the United States

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.

The Milwaukee M18 FUEL 18V brushless impact wrench stands out with an impressive torque of up to 2,000 ft-lbs, making it one of the most powerful cordless models available. Its 1-inch drive size is ideal for heavy-duty tasks, especially those involving large lug nuts. Powered by two high-capacity 12.0 Ah lithium-ion batteries, it offers excellent runtime, capable of handling up to 120 lug nuts on a single charge, which is great for demanding jobs without frequent recharging.

The tool’s brushless motor and REDLINK Plus intelligence protect it from overload and overheating, increasing durability and reliability. Features like the ONE-KEY system allow users to customize torque settings to avoid overtightening, adding precision and control that’s useful for professionals who need consistency. The adjustable D-handle and removable side handle improve ergonomics, but at 23.2 pounds, it’s relatively heavy, so it might feel bulky during extended use. The built-in LEDs help illuminate dark work areas, enhancing usability.

While the price and weight might be a consideration, this impact wrench is well-suited for mechanics, heavy equipment maintenance, and anyone needing powerful, cordless torque with smart control features.

The Milwaukee 2767-20 M18 FUEL High Torque 1/2" Impact Wrench is a solid choice if you're looking for powerful performance. It delivers up to 1000 foot-pounds of torque, which is excellent for heavy-duty tasks like automotive repair or industrial work. The 1/2-inch drive size is standard and versatile, fitting most impact sockets you'd need. Being battery-powered, it offers good mobility without the hassle of cords, and although batteries aren’t included with this bare tool, it runs on Milwaukee’s M18 battery system, known for reliable power and decent runtime.

Weighing 6 pounds and measuring about 9.65 inches long, it strikes a fair balance between power and handling, though it’s a bit on the heavier side compared to some competitors, which might cause fatigue during extended use. The rubber overmold finish improves grip and comfort, making it easier to hold securely. Milwaukee is known for durable tools, and this model appears rugged enough for frequent use in tough conditions.

On the downside, since it’s a bare tool, you’ll need to invest separately in batteries and a charger if you don’t already have them. Also, it’s not the lightest option out there, so if you prioritize portability and lighter weight over maximum torque, you might find it a bit bulky. For anyone needing a high-torque impact wrench that can handle demanding jobs with solid build quality, the Milwaukee 2767-20 is a strong contender.
