The IQV20 Compact 3/8” Impact Wrench from Ingersoll Rand has breakaway torque up to 400 lb.-ft., a maximum speed of 2,800 RPM, and 4,200 blows per minute (BPM) for rapid removal of fasteners. The 1/2" or 3/8" square drive is for use with impact-rated sockets. As the lightest in its class at 2.3 lbs., the company says it reduces fatigue and improves tool control while tight spaces can be easily accessed. It's 5.3" in length from tip-to-tail with an overmolded ergonomic grip that provides comfort for extended periods of use. The patented 360-degree LED shadowless light ring illuminates the fastener from all sides. Three speed options with a variable speed trigger covers a wide range of applications. A 3-year limited warranty is included. Kits, W3131-K22 or W3151-K22, are available and include one impact wrench, one BL2023 battery, one BL2012 battery, and one battery charger.
