FAQs:
- Q: How much torque does the Ingersoll Rand W8191-K2 deliver?
A: The W8191 impact wrench delivers up to 2,000 ft-lbs (2,710 Nm) of breakaway torque for loosening fasteners and 1,300 ft-lbs (1,765 Nm) of forward torque. Breakaway torque is a removal rating and should not be interpreted as a calibrated tightening value. - Q: What is the difference between the W8191-K2 and W8171-K2?
A: The primary difference is drive size. The W8191-K2 features a 1" square drive, while the W8171-K2 uses a 3/4" square drive. Both have the same published torque, speed, and impact ratings. Choose the model that matches your impact socket inventory and fastening requirements. - Q: What is included in the W8191-K2 kit?
A: The manufacturer specifies one W8191 cordless impact wrench, two BL2022 IQV20™ batteries, and one BC1121 charger. These components are included in the K2 kit configuration, unlike the standalone bare-tool model. - Q: How does the W8191-K2 compare with the W8591-K2?
A: Both models feature a 1" square drive and 2,000 ft-lbs of breakaway torque. The W8191-K2 has a standard-length anvil and measures 8.77" overall, while the W8591-K2 features a 6" extended anvil and measures 14.77". Select the extended-anvil model when additional reach is needed for recessed fasteners. - Q: Can the W8191-K2 be used for final wheel-nut tightening?
A: The wrench can install compatible wheel fasteners, but its power-control settings are not calibrated for final tightening. Use an appropriately rated, calibrated torque wrench to complete tightening according to the vehicle or equipment manufacturer's specifications. - Q: Is the W8191-K2 suitable for mobile service work?
A: Yes. Its IQV20 cordless design eliminates the need for an air hose, making it useful for field repairs and mobile maintenance. The IPX6 rating provides water-jet resistance under specified conditions, but the tool should not be immersed in water.
