The Ingersoll Rand W9491 is a 20 V cordless impact wrench with a 1-inch square drive, built for heavy fastening on trucks, heavy equipment and structural steel. Its brushless motor and multi-gear selector give it the torque and control that 1/2-inch tools cannot match, and it runs on Ingersoll Rand's 20 V battery platform. It suits mechanics and maintenance crews who need cordless freedom on big fasteners. Against 1/2-inch cordless wrenches it is heavier and bulkier, but it reaches torque levels that those tools only approach when plugged in.

Owners of Ingersoll Rand's high-torque cordless tools generally report strong fastening power and durable brushless motors, but note the weight and battery appetite of 1-inch-class wrenches.
