10 Best Highest Torque Impact Wrench 2025 in the United States

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 Ingersoll Rand W9691-K2E 20V High-Torque 1" Cordless Impact Wrench Kit offers impressive power and mobility for those needing a high-torque solution. Its standout feature is the significant torque it delivers: 3,000 ft-lbs for nut-busting and 2,200 ft-lbs for tightening. This makes it ideal for heavy-duty applications like large automotive repairs or industrial maintenance tasks. The cordless design, paired with two 20V lithium-ion batteries and a dual bay charger, ensures that you're not tethered to a power source and can work freely and efficiently for extended periods.

The impact wrench's brushless motor and IP56 rating underscore its durability and efficiency, making it suitable for harsh environments and heavy use. Additionally, the 6" extended anvil provides extra reach, which is beneficial for accessing hard-to-reach areas, and the 360-degree adjustable D handle offers enhanced maneuverability and comfort during use. However, the tool's weight is on the higher side at 25.9 pounds, which might be challenging for prolonged use or for users who prefer lighter tools. Despite its weight, the ergonomic design of the handle helps in maintaining a good grip and reducing user fatigue.

The kit's inclusion of two batteries and a dual bay charger is a practical advantage, ensuring minimal downtime. With a 3-year warranty, it reflects a reliable and durable choice for professional users. The high power comes at a cost, both in terms of the tool's weight and potential price, which might be higher compared to other impact wrenches. This tool is best suited for professionals or serious DIY enthusiasts who require robust performance and can handle the tool's weight and price point.

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.
