This impact driver was a disappointment .It lacked any real power and broke after only a few uses. As someone who works in industrial and scientific fields i need tools that can handle heavy use and stand the test of time. Unfortunately, this was not one of them..
This is a good tool for small screws, especially overhead work. It doesn't work well with 3" SDS screws, but it's great to have a punch that fits in your tool bags.
Pros
Professional driving performance - 975 in-lbs of torque.
