It's about 1.5 times the size and weight of my 1/4" hex drive impact tool but seems to have 4x the power. This obviously isn't going to out drive an air powered impact wrench but has more than enough power to handle lug nuts. The only time this tool failed to impress me was removing large diameter stainless steel fasteners with seriously galled threads (an antenna mount that had been on our office roof for 10+ years.) The DC820B could break the seized 3/8 bolts but didn't have the power to break the 1/2" bolts. It tried and tried but couldn't quite get the job done. I could feel a slight flexing of the tool in my grip that probably robbed torque from the job at hand. To be fair, I had removed more than 50 bolts before attempting to free the seized bolts and didn't take the time to replace the battery so this isn't conclusive, your results may be better. The only real design complaint I have about this tool is the socket retention mechanism. Instead of the spring loaded ball or hog ring systems used on most 1/2 air impact tools this one has a spring loaded "detent pin retention system". On my tool this requires using a small screwdriver or similar tool to push in the retention pin every time you want to change a socket. It was a hassle at first but now I just leave a short impact extension on the tool and change sockets on the extension. I mention this since when looking at the parts diagram it appears that Dewalt has different models that use the hog ring system. One of those might be a better choice if you change sockets frequently. Like one or two other reviewers mine emits a slight burning smell that seems to have gotten less noticeable the longer I use the tool. I have some other Dewalt tools that had the same problem but none have died (so far at least)4 of 4 people found the following review helpful.A lot of power in a small packageBy Jonny B GoodThis tool is small and light but has plenty of power for any 1/2" socket you would be likely to use. It works best with the lithium battery but the nicad works just fine although noticeably heavier. After using this tool hard for several days I'm not sure 5 stars is enough. The work performed per pound would have been unimaginable a few years back.2 of 2 people found the following review helpful.How have I survived without it!By David W. ElmoreA friend of mine has one of these and I had to have one. Wow! My favorite cordless DeWalt, no doubt! First use was to remove the blades from my riding mower....Zip! No holding the blades, off and back on again, so easy! Plenty of power! So, be careful! This thing has enough torgue to snap bolts! I am extremely happy and satisfied with this purchase!See all 17 customer reviews...
