Ingersoll Rand w8171-k2 3/4 in Cordless Impact Wrench

Product Description

The INGERSOLL RAND w8171-k2 is a cordless, brushless 3/4 inch drive impact wrench built for assembly, automotive, maintenance, and construction applications. It delivers up to 2,000 ft-lb of breakaway and fastening torque using a hammer-and-rotation mechanism that drives and removes heavy fasteners without a pneumatic compressor. The brushless motor runs on the IQV20 20-volt DC battery platform and reaches a no-load speed of 1,350 RPM. A 4-position power regulator with timed shutoff on positions 1 through 3 gives technicians fine torque control, while position 4 provides continuous power for fastener removal. The kit includes two 5.0 Ah Li-Ion batteries and one charger.

This impact wrench is suited for heavy-duty fastening tasks where portability matters. Typical applications include truck and fleet maintenance, roadside tire service, structural assembly, and industrial maintenance. The 3/4 inch square drive accepts impact-rated sockets. The tool weighs 7.4 pounds and features a rubberized pistol grip handle and a 360-degree halo ring light around the anvil for visibility in low-light work areas. Cordless operation eliminates the need to run air lines or haul compressors to remote service locations.

Installation Notes

This tool is intended for use by trained mechanics, technicians, and tradespeople familiar with impact wrench operation and torque requirements. Always use impact-rated sockets rated for the torque output of this wrench — standard chrome sockets are not appropriate. Verify fastener torque specifications against the applicable service manual or engineering standard for the assembly being serviced. Inspect batteries and the charger before use and store in a dry environment away from heat sources.
