Ingersoll Rand W9491-K2E Cordless Impact Wrench 1 in Drive

Product Description

The INGERSOLL RAND W9491-K2E is a cordless impact wrench built for heavy-duty fastening in demanding trade applications. Powered by the IQV20 20-volt lithium-ion platform, it delivers up to 2,600 ft-lb of torque and 1,170 blows per minute through a 1-inch square drive. The D-handle grip and 20.125-inch overall length keep it manageable on the job. Two IQV20 lithium-ion batteries and a BC1221 charger are included, so the tool is ready to work out of the box. This wrench is suited for heavy equipment, fleet maintenance, and industrial assembly work where air tools are impractical or unavailable.

This impact wrench is designed for professional use in commercial, industrial, and fleet service environments. Typical applications include removing and installing large fasteners on trucks, heavy equipment, agricultural machinery, and structural steel. The variable speed range of 0 to 890 RPM gives the operator control over seating torque, reducing the risk of fastener damage on sensitive assemblies. Licensed mechanics, ironworkers, and heavy equipment technicians are the primary users of this class of tool.

Installation Notes

This tool is intended for use by qualified mechanics and trade professionals familiar with high-torque impact equipment. Always confirm the square drive retainer pin and ring are fully seated before attaching a socket. Use impact-rated sockets only — standard chrome sockets are not rated for impact tool use and can fracture under load. Follow the equipment manufacturer torque specifications for all fastener applications.
