Reach deep-set fasteners with the Ingersoll Rand W8571-K2 High Torque Cordless Impact Wrench Kit, designed for heavy equipment, fleet maintenance, and industrial repair applications. Powered by the IQV20 20V battery platform, this brushless impact wrench features a 3/4" square drive with a 6" extended anvil for accessing recessed nuts and bolts. Delivering up to 2,000 ft-lbs (2,710 Nm) of breakaway torque and 1,300 ft-lbs (1,765 Nm) of maximum forward torque, it combines substantial fastening capability with cordless mobility, eliminating the need for compressed-air hoses.
The W8571-K2 features four-position IQV Power Control, a variable-speed trigger with electronic brake, and a patented 360° Shadowless LED light ring for improved visibility. Its durable metal casing, rubberized bumpers, and IPX6 water-resistance rating support demanding working conditions. Operating at up to 1,350 RPM and 1,900 impacts per minute, the tool measures 14.77" overall and weighs 7.7 lbs without the battery. The kit includes the W8571 impact wrench, two BL2022 batteries, and a BC1121 charger for a ready-to-configure cordless fastening setup.

FAQs:
- Q: What is the difference between the Ingersoll Rand W8571-K2 and W8171-K2?
A: The W8571-K2 features a 6" extended anvil and measures 14.77" overall, while the W8171-K2 has a standard-length anvil and measures 8.77". Both use a 3/4" square drive and are rated at 2,000 ft-lbs of breakaway torque and 1,300 ft-lbs of maximum forward torque. Choose the W8571-K2 when additional socket reach is required. - Q: Does the 6" extended anvil increase the wrench's torque?
A: No. The extended anvil improves access to recessed fasteners rather than increasing the published torque rating. Both the standard and extended-anvil models share the same manufacturer-rated breakaway and forward torque specifications. - Q: What comes with the W8571-K2 kit?
A: Ingersoll Rand specifies one W8571 cordless impact wrench, two BL2022 IQV20 batteries, and one BC1121 charger. This kit differs from the standalone W8571 tool configuration by including batteries and a charger. - Q: How does the IQV Power Control system work?
A: The tool offers four forward power settings: Hand Tight, Wrench Tight, Mid Power, and Max Power. These provide different fastening outputs, with timed shutoff in the lower settings as described by the manufacturer. They are not calibrated final torque settings; use a torque wrench when a precise tightening value is required. - Q: Can the W8571-K2 be used for mobile heavy equipment maintenance?
A: Yes. Its cordless design and extended anvil make it useful for accessing suitable fasteners during field repairs. Select impact-rated sockets, verify sufficient working clearance, and follow the manufacturer's battery and environmental operating instructions.
