It's a 3/4" impact with 1200 ft/lbs of torque. http://www.skhandtool.com/Default.aspx?fusemode=10&pid=92141
Guy is selling it cheap ($150) a little worn but will do for me unless it has some kind of weakness I haven't been able to find online. Basically I have a 1/2" with about 450 ft/lbs but need something a lot stronger for soem of the hard to reach palces and my 1" impact is a monster and basically a mistake at this point I will sell it once I get a decent 3/4". So any info helpful.
I would go for it, if anything not up to par, there is nothing complicated in there(2 bearing, a drum, 4 fiber vanes, 1 hammer,1 anvil). & SK you can have parts anytime.
