The Ingersoll Rand QX Series Ergonomic Tightening System (ETS) delivers short pulses of energy into the fastener during tightening to help the operator retain control of the tool. The motor control algorithm is designed to minimize the average force experienced by the operator, helping to protect the user from injury. This tightening system is available on Ingersoll Rand's QX Series cordless fastening tools in pistol and right angle configurations that range from 1.33 ft-lbs to 59 ft-lbs of torque.
