This is a handy swage tool that does indeed do its job, if a bit crudely. With a few practice runs, I managed a clean, expanded end on a common 1/2" copper pipe that received a corresponding piece of copper pipe nice and snug and soldered up nicely. For all of 8 bucks or so, this seems like a good value so far!The tool itself is rather basic, and consists of a series of "steps" that expand a soft metal pipe in increments. The 1/4" hex shaft on the tool is convenient and easy to chuck into a drill, and the included keychain/bit holder is a nice feature. The bit itself is made from a stout steel, and hasn't shown any indications of heavy wear after a handful of passes.I found that going mid-speed was the best approach...no so slow as to have to ram your way through the pipe, but not so fast as to heat up your workpiece until it's smoking-hot.The resulting swaged end on a 1/2" pipe winds up being about 3/8" deep, which is satisfactory. I'd admittedly prefer to have about 1/2" of engagement, but that's not a deal breaker. I'll be soldering up a series of pipes soon for a project, and I'll look forward to using this handy tool and reporting the results!
