Comparison with DeWalt's strongest impact

The DeWalt DC840 is a powerful impact driver, but it is not the strongest impact driver that DeWalt produces. The DeWalt 20V MAX XR Impact Driver, which produces a max torque of 1,825 inch-pounds, is the most powerful impact driver that DeWalt produces. However, the DC840 is still a very powerful impact driver, and it is a good choice for most users.

Difference between DeWalt Type 1, 2, and 3

The DeWalt DC840 is a Class 1 construction tool. This means that the tool is grounded but not double insulated. Class 2 construction tools are double insulated, and Class 3 construction tools are grounded and double insulated. The type of construction of a tool is important to know because it can affect the safety of the tool.
