Ingersoll Rand W9491-K4E High Torque Cordless Impact Wrench Kit | 1" Drive Size | Standard Anvil | 2600 (ft-lbs) Nut-Busting Torque

For fleet maintenance technicians and heavy equipment mechanics who need high fastening power without the restrictions of pneumatic hoses, the Ingersoll Rand W9491-K4E High Torque Cordless Impact Wrench Kit delivers up to 2,600 ft-lbs of nut-busting torque (the maximum breakaway force available for loosening stubborn fasteners). Equipped with a 1-inch square drive and standard anvil configuration, the W9491 provides 2,200 ft-lbs of maximum forward fastening torque for large bolts on commercial trucks, construction equipment, and industrial machinery. Its 890 RPM maximum free speed supports efficient fastening and removal, while the standard-anvil configuration keeps the tool shorter than its extended-anvil counterpart for improved maneuverability around equipment assemblies.

As part of the Ingersoll Rand W9000 Series, the W9491 uses two IQV20 20V lithium-ion batteries simultaneously to provide cordless operation without an air compressor, generator, or hydraulic power unit. The IQV Power Control System offers four operating settings, including Full Power Reverse, Snug Mode, Mid-Power Mode, and Full Power Forward, giving technicians greater control when starting fasteners or removing high-resistance bolts. A balanced D-handle design with a 360-degree adjustable auxiliary handle helps operators maintain a secure grip during high-torque work. Measuring 20.1 inches in length and weighing 27.5 lbs with batteries installed, the tool is suited to equipment servicing where reach and available working space matter. The W9491-K4E kit includes four BL2022 5.0 Ah batteries, a dual-bay charger, and charger power cord, providing additional batteries for successive work cycles.

FAQs:

• Q: What is the difference between the Ingersoll Rand W9491-K4E and W9691-K4E?
  A: The W9491-K4E features a standard anvil, measures 20.1 inches in length, and provides 2,600 ft-lbs of nut-busting torque. The W9691-K4E has a 6-inch extended anvil, measures 26.1 inches in length, and delivers 3,000 ft-lbs of nut-busting torque. Both models provide 2,200 ft-lbs of maximum forward fastening torque and use the same IQV20 battery platform.
• Q: How many batteries are needed to operate the W9491?
  A: The W9491 requires two compatible IQV20 20V batteries installed simultaneously. The W9491-K4E package includes four BL2022 5.0 Ah batteries, giving operators an additional pair for continued work after the installed batteries need recharging.
• Q: Can the W9491-K4E be used to remove heavy truck wheel nuts?
  A: Yes. The tool's 1-inch square drive and 2,600 ft-lbs nut-busting torque make it suitable for removing large wheel fasteners when the required torque falls within its capabilities. Use properly rated impact sockets and follow vehicle manufacturer tightening requirements during reinstallation.
• Q: What do the Snug and Mid-Power settings do?
  A: Snug Mode provides up to 180 ft-lbs at 500 RPM, while Mid-Power Mode provides up to 400 ft-lbs at 540 RPM. Both settings incorporate automatic shutoff to help manage fastening before final tightening. Full Power Forward supplies up to 2,200 ft-lbs at 890 RPM for larger fastening operations.
• Q: Is the W9491-K4E suitable for work away from a repair shop?
  A: Yes. Its cordless battery system eliminates dependence on an air hose or compressor during operation. The standard anvil and four-battery kit make it practical for fleet service vehicles, remote equipment maintenance, and other field repairs where high torque is needed.
