A cordless impact wrench saves you time and effort when changing tires, working on suspension, or fixing stubborn bolts. The right tool depends on what you need it for: for regular cars, 500–1200 Nm is enough; for SUVs and stuck bolts, go for 1300–2000 Nm; for heavy trucks, you’ll need at least 2500 Nm with a 3/4″ drive. Key things to look for: 1/2″ or 3/4″ drive, 18V battery (compatible with Makita or Milwaukee platforms), a brushless motor for durability, and advertised torque, which tells you what kind of jobs the wrench can handle.
How to Choose an Impact Wrench: Cheat Sheet
- Advertised torque: 500–1200 Nm is great for cars and small SUVs; 1300–2000 Nm is an all-purpose class for most stuck bolts; 2500 Nm and above is for heavy trucks and off-roaders with large fasteners.
- Socket size: 1/2″ fits most car repairs, 3/4″ is better for heavy trucks and large bolts.
- Motor: Brushless motors last longer and provide better power. Multiple speed/impact modes and auto-stop features make your job easier.
- Battery compatibility: Models fit Makita 18V or Milwaukee 18V platforms and are usually sold as bare tools (no battery or charger included), so make sure they work with your batteries.
- Weight and size: Lightweight models are easier to use overhead or in tight spots.
- Kit contents: Check if the battery and charger are included or need to be purchased separately.

Quick Answers to Common Questions
Is 1200 Nm enough for car wheels?
Yes—it’s more than enough for most cars and SUVs. For stubborn lug nuts and larger vehicles, look for 1800–2000 Nm models.
1/2″ or 3/4″ drive—which do I need?
1/2″ is the universal standard for cars, SUVs, and light trucks. 3/4″ is for heavy trucks and specialized jobs with big fasteners.
Can you fully tighten lug nuts with an impact wrench?
An impact wrench is perfect for quick removal and snugging up lug nuts, but final tightening should always be done with a torque wrench to avoid over-tightening or warping the bolts.
What sockets should I use with an impact wrench?
Only use impact-rated sockets made from hardened steel. Regular chrome sockets may crack or shatter under impact loads.
How heavy is an impact wrench and is it comfortable for overhead work?
Weight depends on the model: compact 500–1200 Nm tools are usually under 4.5 lbs (without battery), general-purpose 1800–2000 Nm ones are about 4.5–5.5 lbs, high torque models can be heavier. For overhead jobs, stick to options under 4.5 lbs.
What does \"advertised torque\" mean, and how should I use this info?
The advertised torque on product listings is the maximum rated output—which may differ from real-world performance. Use torque ratings to match the tool to your needs: 500–1200 Nm for regular cars, 1300–2000 Nm for all-purpose use, and 2500 Nm+ for heavy-duty vehicles.
When shopping for a cordless impact wrench, match the torque class to your tasks, check for battery compatibility, and don’t forget impact sockets or adapters—they make your work faster and safer. The right tool turns tire changes into a five-minute job and saves you tons of effort in the garage.
