FAQs:
- Q: How much torque does the Ingersoll Rand W8171-K2 deliver?
A: The W8171 impact wrench provides up to 2,000 ft-lbs (2,710 Nm) of breakaway torque for loosening fasteners and 1,300 ft-lbs (1,765 Nm) of maximum forward torque. Breakaway torque is a removal rating and should not be interpreted as a calibrated tightening value. - Q: What is included in the W8171-K2 kit?
A: According to Ingersoll Rand's product flyer, the kit includes one W8171 cordless impact wrench, two BL2022 batteries, and one BC1121 charger. The included batteries and charger distinguish this kit from a bare-tool purchase. - Q: What is the difference between the W8171-K2 and W8191-K2?
A: Both kits provide 2,000 ft-lbs of breakaway torque and use the IQV20™ battery platform. The W8171-K2 features a 3/4" square drive, while the W8191-K2 uses a 1" square drive. Choose according to your impact socket sizes and fastening requirements. - Q: Can the W8171-K2 be used for precise torque tightening?
A: The four power-control settings help manage fastening output, but they do not replace a calibrated torque-control system. For wheel nuts and other safety-critical fasteners, complete final tightening using a calibrated torque wrench according to the equipment manufacturer's specifications. - Q: Is the Ingersoll Rand W8171-K2 suitable for outdoor service work?
A: Its cordless configuration is useful for mobile repairs and outdoor equipment maintenance. The tool also has an IPX6 water-resistance rating, but this does not mean it is waterproof or suitable for immersion. Follow the manufacturer's operating and battery safety instructions.
