Hilti says the tool is designed to bring 1-inch A325 bolts to the proper tension as well as drive large screw anchors into concrete.
Equipped with a double hammer impact mechanism, double the torque, and a metal front end, Hilti says the battery-powered SIW 9 A22 delivers the performance of a corded tool with reduced vibration.
The tool is covered by Hilti’s 20-2-1 warranty which backs the tool for 20 years of repair or replacement of defective parts with two years of no cost repair, including wear and tear. Hilti guarantees a 1-day turnaround on all repairs.
