The product is an ideal tool for professional or unskilful use. The machine is not only compact and lightweight, which makes it easier to handle, it also uses a powerful motor for quick and impactful work. The features of the machine looked promising, thus we set out to try it.

Great features

  1. It is compact and lightweight: The machine is small in size. This makes it easy to handle and work with and can be used in tight spaces. The body is made of aluminum which makes it lightweight and thus makes it easy for the user to use it for long durations of time without getting tired.
  2. One hand control: There is yet another feature that makes it a user-friendly machine. It has a unique one hand control system, which allows the user to set the tool on forward or reverse, depending on the type of work that is being done.
  3. It has a powerful motor: The motor used to build the product generates a torque of 550 ft. lbs, which makes it much quicker and efficient. Thus, it has power higher than most of the other impact wrenches. This is why it can be used by professionals such as carpenters and mechanics, for heavy duty work.
  4. It works on compressed air: Unlike the cordless or corded types, this one is no electricity or battery operated. Thus, its work is not affected by the battery charge and does not stop in the absence of a power supply. Consequently, the machine does not slow down.
