The fact that the Milwaukee 2763 Gen 1 high torque now has a stronger big-brother, but still finished 3rd deserves big kudos. In fact, receiving 86.1 points, it only misses 2nd by 0.3 points. While some others above suffered by finishing mid-pack, this is actually a plus for the Milwaukee. The difference is, the 2763 didn’t drastically fall short in any area, like the others. Even though the price is higher than several, with it’s 5-year warranty, features, and ergonomics, it’s still a great value.

And if the lug nut is in a position that is frequently exposed to the elements – especially water – you’ll have to take into consideration the possibility that your lug nut could quite possibly rust over and cause some major problems for you. In any of the above situations, you’re going to need a lot more torque power to get the lug nut out than it took to put it in originally.
Many mechanics probably have the MAC Tools BWP151 in their tool arsenal, and rightly so. This is a very powerful impact gun, and it shows. In the end, the MAC BWP151 finished with 81.4 points in our shootout. In the power category, it and the DeWALT finished neck and neck, in 3rd and 4th place, so it delivers plenty of power. The MAC Tools impact should have done much better in our speed (repetitive power) testing, but it seemed to have a fraction of a second longer lag, from the time you pull the trigger until the gun starts.

Across the board, the Bosch HTH181 wins for being the most ergonomic, and this was almost unanimous from our users. Milwaukee’s Gen2 (2767) and Ingersoll Rand’s W7150 tied for second in ergonomics. The Ingersoll Rand is also the lightest of the bunch, weighing just 6.88 pounds with the 5.0 Ah battery. Bosch and DeWALT followed in a close 2nd and 3rd, at only 7.04 and 7.10 pounds, respectively. The heaviest tool in the batch is the Matco Tools at 8.02 pounds, with the 4.0 Ah battery.
I bought this on a whim when I walked by it at my neighborhood Denver Walmart. I am a professional mechanic, and this tool has been perfect for light to heavy workload. Using it in a shop where I need it for at least ten cars a day, It works great for every task, especially taking lug nuts off of wheels. I did break it within a year, however, which is Campbell Hausfeld's factory warranty, and I contacted them and I got a completely free replacement, and really great service in the process. No, it's not the absolute best impact wrench, but it is worth much more than the price, as I have had many other brands for way too much money, and this one beats all of them that were worth even up to 300 bucks. Above all, the service and the warranty were the best parts of my experience, and I highly recommend it.
