10 Best Half Inch Air Impact Wrench 2025 in the United States

The Milwaukee 2967-20 M18 FUEL™ 1/2" High Torque Impact Wrench is a strong contender in the half-inch air impact wrench category, particularly for those looking for high performance and durability. With an impressive torque output of up to 1,100 ft-lbs for fastening and 1,600 ft-lbs for nut-busting, this wrench can handle tough tasks with ease. The brushless motor is efficient, reducing wear and extending the tool's lifespan, which is a significant advantage for frequent users.

One standout feature is the AUTO SHUT-OFF control, which limits the torque during hand-tight applications to avoid overtightening. This can be very useful in preventing damage to delicate fasteners. Additionally, the Bolt Removal Control mode helps users maintain control when loosening bolts, which is ideal for preventing dropped fasteners.

Weighing in at 5.94 pounds and measuring 7.6 inches in length, it strikes a balance between being manageable and powerful. The metal construction adds to its durability, making it suitable for both professional and DIY use. However, as a battery-operated tool, it does require an 18-volt battery, which is not included, adding to the cost if you don't already own compatible batteries.

The DEWALT 20V MAX Cordless Impact Wrench (DCF961B) is a powerful tool designed for heavy-duty tasks. It boasts an impressive maximum fastening torque of 1200 ft-lbs and a breakaway torque of 1750 ft-lbs, making it suitable for demanding applications like large pipe flanges and wheel lugs.

The tool offers 3 speed settings and a precision wrench mode to prevent overtightening, adding versatility and control to your work. An LED work light enhances visibility in poorly lit areas, which is a practical feature for many users. However, the tool is quite heavy at 8.4 pounds, which might cause fatigue during prolonged use. Since it's a cordless model, there are no air consumption concerns, but keep in mind that it requires a 20V lithium battery which is not included in the purchase.

In terms of noise, as a cordless impact wrench, it tends to be quieter compared to pneumatic versions. The durability appears solid with a powder-coated finish, and its ergonomics are aided by the efficient design and grip. This tool is ideal for users needing high torque and reliability in their impact wrench, but the weight and need for a separate battery purchase are points to consider.

The Milwaukee 2767-20 M18 FUEL High Torque 1/2" Impact Wrench is a powerful tool designed for heavy-duty tasks. With a torque of 1000 foot-pounds, it stands out in terms of strength, making it suitable for tough jobs like automotive repairs or construction work. Weighing 6 pounds, it is relatively heavy, which might cause fatigue during prolonged use. However, the rubber overmold material enhances grip and ergonomics, providing better control and comfort during operation.

The tool is battery-powered, adding convenience as you are not limited by a power cord, but it's important to note that batteries are not included, which could be an additional expense. Air consumption (CFM) is not applicable here since it's a battery-operated model, so you don't need an air compressor. Noise level wasn't specified, but high torque tools generally produce significant noise, so using ear protection might be wise.

Durability is implied through its robust design and the reputable Milwaukee brand. If you need a reliable, powerful, and well-designed impact wrench and are comfortable with its weight and additional battery purchase, the Milwaukee 2767-20 is a strong contender.
