The next time you need to drive fat lag screws or loosen large, corroded nuts, retire your ratchet wrench and reach for the DEWALT DC820KA Compact Impact Wrench. Driven by an 18-Volt XRP extended-run battery, the -1/2 in.-drive, variable-speed wrench delivers both rotation (0-2,400 RPM) and concussive blows (0-2,700 BPM) directly to the fastener. The result is impressive 1,740 in. lbs. of turning force. Other features include: compact, lightweight - just 4.6 lbs. design; frameless motor with replaceable brushes, textured, anti-slip grip, all-metal transmission, heavy-duty magnesium gear case for smooth operation; and a unique impact mechanism that reduces kickback and directs all that torque to the fastener.

  • Heavy duty DEWALT built motor provides long life under continuous heavy use conditions
  • 0-2,100 RPM /0-3,000 ipm for fast application speed
  • Durable all metal gear case and transmission provide jobsite ready durability
  • 160 ft.-lbs. of max torque provides power to perform a wide range of fastening applications
  • Variable speed trigger and electric brake provide control for tightening and loosening fasteners
  • Textured anti slip comfort grip provides maximum comfort and control
  • Heavy duty impact mechanism directs torque to fastener without kickback
  • Compatible with DEWALT 18-volt system and works with all 18-volt DEWALT batteries (XRP, Nano and compact)
  • Other batteries and chargers sold separately, this tool works with these batteries (DC9096, DC9180) and chargers (DCB103, DW9117, DC9310, DC9319, DC9320, DC012)

Rated 4.0 out of 5 by 3 reviewers.
Rated 5.0 out of 5.0 by Great product with a lot if punch. This product is a great addition to any DIY it has plenty of punch to pull off a tire and drive those lag bolts. It isn't the one with the most torque but its the cheaper version of the big impact wrench. Great tool and would recommend it. The only Con i have is that it needs a fresh battery or slightly used battery to break loose stubborn lug nuts but its because its not the most powerfull option and I bought this one to save a little money so its not really a con but i wanted to inform any viewers.

Rated 2.0 out of 5.0 by Cheap. Not for lug nuts. Not enough power to break free lug nuts on a Honda Civic torqued to 90 ft lbs. I also tried this on many clean motorcycle bolts, it did not break any of them free. I tried with fully charged batteries and tried both batteries. Not worth it. I had to return it. My little cordless 3/8" Makita Impact could (literally) loosen bolts that this one could not. I would not recommend this one. *Also, this is made in Mexico....... January 17, 2014
Rated 5.0 out of 5.0 by I love it! So much better than dragging around a hose. This impact has plenty of power and I can get up and down a ladder with it very easily. February 21, 2012
