the dewalt would probably fall to pieces. If it did survive the test the trigger switch would fail you as all dewalt 18v gear I have ever owned has dies from trigger failure or burnout within a year.
I'd pretty much run with that...
It's got DeWalt written on the side, so no, it'll be crap. Might last OK as a DIY tool but used every day for trade use it'll be no good at all. I went DeWalt for a while as I was taken in by the perception of quality. On five tools (two 18v XRP combis, an 18v angle drill and two 18v impact drivers), I've suffered trigger failure (twice), torque ring failure (four or five times...lost count), gearbox failure (twice), burnout and the failure of six 3.0aH batteries, which stopped taking charge despite being carefully looked after according to DeWalt's own instructions. This was all in the space of about 15 months.
Take a look at Ryobi for light/medium use, or the Bosch Professional range for everyday use (lovely 3-year warranties with five day turnaround, not that I've ever had to use it). Not used Hilti so can't comment there although have heard a lot of good stuff about them along with frightening price tags. Looks like PB got a good deal on his.
