The metal housing and steel hammer case of the 2161 Series Impact Wrench makes this one of the toughest tools on the market. You'll also benefit from the twin hammer impact mechanism, which provides a more even impact with every blow and makes it less sensitive to changes in air pressure.
The 2161XP combines a six-vane high output air motor, through-bolt construction, ergonomic handle and housing design to create an impact tool that offers increased power and durability like no other.
