Very disapointed with Bosch....now it's on a par with Black n Decker, oh sorry DeWalt....noisey and not so cheap....
WELL, It depends WHICH Bosch Impact driver model...
Their Gen-1 was quite mediocre, Gen-2 also mediocre, but Gen 1.5 that is still being sold (
I would better say, DISPOSED OF) in many countries, advertised as a "180 Nm" torque, is an absolute piece of crap... it still has a brushed motor, and its anvil is so small and badly matched, that its real torque is just a fraction of the very inflated Bosch factory specification!
BUT, the most recent mid-range model, sold either as "GDX 18V 1860 C" (which means 1860 inch-Lb or 155 Ft-lb or 210 Nm) or a similarly powered one labeled as GDX 18V 200, are good enough (
IF you already have 18V Bosch batteries, that is !)...
I would say that the model 1860C (
or CN, depending on the country) is perfectly capable for carpentry, but barely just enough for automotive or metal working. In other words, it will remove the wheel nuts of a midsize car, but it could not be enough for a small truck or suspension work.
I am only considering the 1860C bare tool because I bought another 18V Bosch tool thanks to a heavy discount sale offer in my country at Home-Depot, as they were giving a basic 18 V charger and two 4.0 Ah standard batteries for free, included in the purchase of any 18V Bosch bare tool, so that I will probably going to use one of the batteries to power the drill and the other to power the impact driver. The model of impact driver that they were selling that weekend, was the "GDX 18V 180 Li" (also labeled as "GDX 18V 1600b" in other countries),, which as I already said, is brushed, not very compact, and is PLAINLY, TOO WEAK!... So I returned it to the store immediately together with its charger and pair of batteries! (
which I suspect, Bosch is pushing out due to them moving onto the more powerful (but highly expensive new line of batteries, named "CORE")...
For those considering the purchase of an impact driver, and specially, a strong Impact "wrench", by all means do a YouTube search for the "
Torque Test Channel", as they truly test the torque and performance of many impact tools, and publish a comparative table of their findings, which seem very revealing and scandalous at times... that table which includes a lot of brands and models is not given "for free", as they sell it; but the revelations and throughly tested results could be "enlightening".
