Below are listed 5 of the most important aspects of this impact driver:

1. The BTD142HW comes with a 4-pole variable speed motor which allows it to achieve greater power at lower speeds than the more common 2-pole motors--thereby resulting in less wear and tear on the driver.

   The charger also has an embedded memory chip which allows continuous communication between the charger and the battery for the most efficient possible charge.
