The Ingersoll Rand IQV20 High-Torque Impact Wrench Sets A New Standard for Cordless Power

Ingersoll Rand IQV20 High-Torque Impact Wrench Performance

Ingersoll Rand IQV20 High-Torque Impact Wrench
  • No-Load Speed: 1350 RPM
  • Impact Rate: 1900 IPM
  • Fastening Torque: 1300 ft-lbs
  • Breakaway Torque: 2000 ft-lbs

Let’s Talk Speed

When it comes to speed, these high-powered brushless impact wrenches top out at 1,350 RPMs with an impact rate of 1,900 IPM. That’s a little slower than some of the other cordless models on the market, but with its higher torque specs, it’s not really a surprise since there’s typically an inverse relationship between speed and torque.

IQV Power Control System

Power regulators are nothing new in the pneumatic world, but Ingersoll Rand took it one step further. The IQV Power Control System dial on the rear of the tool body allows you to adjust the fastening torque from Hand Tight all the way up to Max power in seconds. With that level of control, these high-powered tools incredibly useful beyond just breaking frozen nuts and bolts.

Considering that comparable rear-handle models in this class can easily hit 20 pounds, I’d say those specs are pretty respectable.


Overall, I was pleasantly surprised by these tools. Like I mentioned before, both models are well-balanced and feature a textured rubber overmold grip. Additionally, there are rubber bumpers on the sides and rear of the tool for increased protection on the jobsite.
