The Einhell IMPAXXO 18/400 is the heavyweight champion of the Power X-Change impact range. Engineered for those who need more than just standard power, this brushless impact wrench delivers a massive 400 Nm of torque, making it capable of loosening even the most stubborn, rusted, or over-tightened bolts. By utilizing a brushless motor, the IMPAXXO 18/400 provides more power and extended runtimes while eliminating the mechanical wear associated with carbon brushes.

What sets this tool apart is its versatility; it features 3 speed/torque settings, allowing you to switch from high-power wheel nut removal to more delicate fastening tasks with the push of a button. The 1/2" external square drive ensures a robust connection with heavy-duty impact sockets, and the integrated LED light ensures precision in poorly lit areas like wheel wells or chassis undercarriages. Whether you are a professional automotive technician or a serious DIYer working on a 4x4 restoration, the IMPAXXO 18/400 offers the cordless freedom and raw power required for industrial-scale results.

Top 3 Frequently Asked Questions

1. Is the IMPAXXO 18/400 strong enough for a professional workshop? Yes. With 400 Nm of torque and a brushless motor, it is designed to bridge the gap between DIY and professional use, making it suitable for high-volume automotive tire services and structural steel work.

2. Why are there three different speed settings? The three settings (Low, Medium, High) allow you to limit the torque. This is vital because 400 Nm is enough to snap smaller bolts or strip threads. The lower settings provide the control needed for smaller fasteners while the high setting provides full power for wheel nuts.

3. Which battery is recommended for this model? Due to the high torque requirements, we strongly recommend using a Power X-Change 4.0 Ah battery or higher. Larger batteries (5.2 Ah or 8.0 Ah) will provide even more consistent power delivery during prolonged heavy-duty use.
