A few years back at SEMA we got our first glimpse of the new IQ20 cordless line and the W7150 from Ingersoll Rand. While we didn't get to test it, we did get to touch and feel it. It stood out as a quality tool from its polished aluminum casing to its stout overall feel. I can sum up the W7150 with one word “Power”. It easily has the power of most pneumatics and is the most powerful cordless impact ever tested here at TIA.
When you first open the case of the W7150 you notice how nice everything is laid out. Secondly, you notice the shiny aluminum hammer housing. It glows out at you like the suitcase in Pulp Fiction. The 7150 may not contour to your hand like the DeWALT 20V MAX line but it sure does feel nice. The overall ergonomics of this tool are very comfortable and better than any pneumatic I have used. It absorbs almost all the impact forces so your hand doesn't have to. This will result in less user fatigue and better control. Rubber over-mold was put in the right places and when you lay the tool down on its side you won't mar the surface.

- Max Reverse Torque: 780 ft-lbs
- Nut Busting Torque: 1100 ft-lbs
The 20v battery pack is a 3.0 Ah with a fuel status gauge on it. The battery release consists of squeezing the two side buttons and pulling. The fit was tight and there was no sloppy rattling of the pack, it felt solid. The charger is large which takes up bench space but also adds stability. It has one of the coolest features we have seen on a charger, a USB charge port. You can charge all your 5V USB devices like tablets and smart phones right from the charger. The charger has a simple LED system to notify you the status of the charge and also beeps when finished. Charge time is roughly 1 hour.
My only gripe with the W7150 is the lack of an LED light. Light is a mechanics friend and is always needed. The W7150 screams quality and is the top dog in the 18/20V market right now. It is a quality tool that is built to last in the destructive automotive environment. It took on every nut and bolt that we threw at it. If I were to only have one impact this tool would be my choice.
