Ingersoll Rand W9491 20V High Torque Cordless Impact Wrench | 1" Square Drive | 2600 (ft-lbs) Nut-Busting Torque | (Bare Tool Only, Battery Not Included)

When servicing large fasteners on commercial trucks, construction equipment, and industrial machinery, the Ingersoll Rand W9491 High Torque Cordless Impact Wrench provides substantial breakaway power without the restrictions of compressed air hoses or external power connections. Part of the W9000 Series IQV20 cordless platform, this impact wrench delivers 2,600 ft-lbs of nut-busting torque (maximum breakaway torque for loosening stubborn fasteners) and 2,200 ft-lbs of maximum fastening torque for high-torque bolting operations. Its 1-inch square drive features a socket retainer ring and thru-hole for securing compatible impact sockets, while the standard-anvil configuration provides a shorter overall profile than the extended-anvil W9691. With a maximum free speed of 890 RPM and 1,170 blows per minute, the W9491 supports large-fastener removal and installation in fleet maintenance, equipment repair, and industrial service environments.

The Ingersoll Rand W9491 operates using two 20V IQV20 lithium-ion batteries installed simultaneously, offering cordless mobility for roadside assistance and field maintenance operations. Its IQV Power Control System provides four selectable operating modes, including Snug and Mid-Power settings with automatic shutoff near their specified torque levels, helping technicians manage preliminary fastening before final torque verification. A brushless motor eliminates mechanical brush wear, while the balanced D-handle configuration and 360-degree adjustable auxiliary handle provide flexible gripping positions. The 20.1-inch overall length and 24.3 lb bare-tool weight make this standard-anvil model a practical option where the additional reach of an extended anvil is unnecessary. The tool also features IP56-rated protection against dust and water jets for use in challenging maintenance environments.

*Note: This product is supplied as a bare tool only. Batteries and charger are not included and must be purchased separately. The W9491 requires two compatible IQV20 batteries installed simultaneously for operation. Please confirm battery and charger availability before ordering.

FAQs:

• Q: Does the Ingersoll Rand W9491 include batteries and a charger?
  A: No. The W9491 is the bare-tool configuration and does not include batteries or a charger. Two compatible IQV20 lithium-ion batteries are required for operation. Buyers who need batteries and a charger can consider the W9491-K2E or W9491-K4E kit configurations.
• Q: Which batteries are required to operate the W9491?
  A: The manufacturer specifies two BL2022 IQV20 20V lithium-ion batteries. Both batteries must be installed together for the impact wrench to operate. The W9491 is part of the broader IQV20 battery platform, but buyers should confirm compatibility before selecting alternative battery models.
• Q: How is the W9491 different from the W9691?
  A: The W9491 uses a standard anvil and provides 2,600 ft-lbs of nut-busting torque, while the W9691 features a 6-inch extended anvil and delivers 3,000 ft-lbs of nut-busting torque. Both models offer 2,200 ft-lbs of maximum fastening torque. The W9491 is shorter and lighter, making it a suitable choice when an extended anvil is not required.
• Q: Can the W9491 tighten heavy truck wheel nuts?
  A: Yes, when the fastener requirements are within the tool's operating capabilities and suitable impact-rated sockets are used. The tool provides up to 2,200 ft-lbs of maximum fastening torque. Final wheel-fastener tightening must be checked using a calibrated torque wrench according to the vehicle manufacturer's specifications.
• Q: What is the purpose of the Snug and Mid-Power modes?
  A: These modes help technicians control preliminary fastener tightening. Snug Mode provides automatic shutoff near 180 ft-lbs, while Mid-Power Mode provides automatic shutoff near 400 ft-lbs. These settings assist with fastening control but do not replace calibrated torque verification for critical joints.
