TL;DR Brushless ½" cordless wrench rated 275 ft-lbs max fastening on the CRAFTSMAN V20 platform; adequate for passenger-car lug nuts but underspec for heavy-truck or seized-suspension work.
Brushless ½" hog ring impact wrench rated 275 ft-lbs max fastening on the CRAFTSMAN V20 (20V MAX) Li-ion platform, stocked widely at Lowe's and Amazon. Bare tool ~4.0 lbs, 8.82" long, with 2 speed modes plus variable trigger. No independent torque meter test located; community evidence draws from fastener-removal outcomes only. Highly rated owner feedback on Amazon shows no stall-out pattern on passenger-car lug nuts. Electric, no air compressor required.
A home mechanic doing tire rotations and light under-car work on passenger vehicles, especially one already on the CRAFTSMAN V20 platform, will find this capable and platform-convenient. Skip it for heavy-duty truck wheel studs or seized suspension bolts; a higher-torque model with community-confirmed 500+ ft-lbs real-world output serves those jobs better.
No UL or ETL certification confirmed as of 2026-05-22. Li-ion battery, no documented thermal incidents. Hearing protection situationally appropriate for extended use. Standard e-waste disposal; Call2Recycle handles the V20 battery pack.
No. The CMCF920B is a bare tool · it includes the impact wrench only. A compatible CRAFTSMAN V20 (20V MAX) Li-ion battery and charger are sold separately. The wrench works with any battery in the CRAFTSMAN V20 platform.
Highly rated owner feedback on Amazon supports reliable lug nut removal on standard passenger vehicles. No independent calibrated torque meter test was located · the 275 ft-lbs max fastening spec is from the manufacturer. For heavy-duty truck wheel studs or severely seized suspension bolts, this 275 ft-lbs rating is on the low end of the ½" class; a higher-torque model with community-confirmed 500+ ft-lbs real-world output serves those jobs better.
No independent US safety certification (UL or ETL) was confirmed for the CMCF920B as of 2026-05-22. The UL Product iQ lookup was inconclusive for this model, and the product listing does not state CE certification. The health score reflects a certification deduction.
