10 Best Impact Wrenches

The Milwaukee M18FHIW2F12-502X is a powerful 18V cordless impact wrench designed for demanding fastening tasks. It offers impressive torque, with 1491 Nm for tightening and a nut-busting peak torque of 2034 Nm, making it well suited for heavy-duty jobs like automotive repair or industrial use. The 1/2-inch drive size is standard for versatility and compatibility with many sockets.

Its compact length of 193 mm helps reach tight spaces where larger tools might struggle. The tool runs at a no-load speed of up to 2000 RPM, allowing you to complete tasks noticeably faster compared to older models. The 4-mode DRIVE CONTROL feature lets you adjust speed and torque for different applications, adding to its flexibility. Battery powered with included 5Ah batteries and a charger, it is portable and cordless, though it weighs about 7.4 kg with packaging, which may affect comfort during extended use.

Milwaukee’s robust gear case and vibration control system add durability and comfort, making this impact wrench a reliable choice for professionals or serious DIYers who need a balance of power, control, and portability in a compact tool.

The Makita DTW1002Z is a powerful cordless impact wrench designed for demanding jobs where strong tightening torque is essential. It offers a high maximum torque of 1000 Newton meters, making it suitable for working with standard bolts ranging from M12 to M30 and high tensile bolts from M10 to M24. Powered by an 18V lithium-ion battery (sold separately), it provides the convenience of cordless use but requires compatible Makita batteries and chargers to maintain warranty coverage. The brushless motor helps improve efficiency and durability while reducing noise to 108 dBA, which is on the louder side but typical for high-torque impact tools.

It features three electronic impact power settings, allowing you to adjust performance to match different tasks, and supports both clockwise and anti-clockwise rotation for fastening and loosening bolts. Weighing about 3.13 kg (roughly 6.9 pounds), it’s somewhat heavy, which could affect comfort during extended use, but it balances power and ergonomics reasonably well. The fixed square drive and compact length (about 23 cm) help in accessing tighter spaces. This model comes without batteries and charger, so those need to be purchased separately.

Users appreciate its solid build and reliability, reflected by a strong customer rating of 4.8 out of 5. This impact wrench is well suited for professionals or serious DIYers needing strong torque and solid performance in a cordless tool, though it may feel heavy for casual users and requires investment in Makita battery accessories.

The DEWALT 18V XR Brushless 1/2" Compact Impact Wrench is a solid choice for those needing a powerful yet lightweight tool for tightening and loosening bolts. It delivers up to 406 Nm of torque, which is strong enough for most automotive and DIY tasks. The 1/2 inch drive size is standard for many sockets, and the hog ring feature allows quick socket changes without fuss.

Weighing just under 1 kg and measuring 24 cm long, it is fairly easy to handle in tight spaces and won't tire your arm quickly. Its brushless motor not only provides good power but also tends to last longer and run cooler than brushed motors. The variable speed trigger and 4-mode switch help you control the tool precisely, making it suitable for delicate jobs as well as tougher ones.

This impact wrench is well suited for DIY enthusiasts and professionals who need a reliable, cordless tool that balances power, weight, and control. Keep in mind this is a bare unit, so you need to have or buy an 18V DEWALT battery separately, which adds to the overall cost.
