My ancient Skil 12v and my modern (cheap, green) Bosch 9.6v will both snap 4mm TurboGold screws occasionally if I forget to turn the torque down.
I am thinking of getting something beefier for driving 6 x 100 screws though.
It may be a decent drill, , but in reality it is a 50-80 quid drill dressed up in an attempt to reel in a few suckers via some dodgy marketing. It is certainly not a top pro drill
Do you have any evidence to support this claim?
Of course not. However products can be manufactured to differing specifications and quality levels (in both senses of the word) and using different labour skill levels and component quality levels.
For example, Makita have manufacturing plants under their control and run to their quality standards in mainland China as well as in other parts of the world, all backed up with spares and service worldwide.
The generic tools come from OEM factories and are built to the spec. and price point (both linked to volume) of the retailer. Quality control, in both senses is secondary to the above, and spares and service typically limited to agreed return rates.
As I've said, it depends on what a person's purchase criteria are. If it's purely price, that's fine, but at least understand the implications of buying on price.
Personally, I look for most of the other factors first.

I think that's the point. Is the product slapped together with unskilled labour at minimal cost and no quality control, or is it done properly with the manufacturer running the factory with his quality control and staking his brand reputation on it?

The primary thing to get "cut" in a cheap tool seems to be the quality of the cells used in the batteries. You only need to look at the number of tools where the retail price of the whole thing is less than the trade price of a set of moderate quality cells to make an equivalent battery pack.
You were originally trying to persuade us that fast chargers on cheap/generic cordless tools wouldn't be 'intelligent' in any way.
While I may (or may not) agree with what you said in this last posting I don't see what it has to do with my original comment (and findings) relating to fast chargers on cheap tools.
Quite probably true but I was not arguing that point. I was just saying (and proving, by taking one apart) that the electronics in cheap/generic tools are not the absolute minimum to get it to function. Apart from anything else I don't believe that would be a sensible way to make the most money, electronics is *so* cheap nowadays you might as well go for a good solution as for a poor one.
Thus newly designed cheap tools probably will have intelligent fast chargers because they won't cost any more than unintelligent ones.
Again you have drifted from the original point, you claimed that fast chargers in cheap/generic tools wouldn't be intelligent.
I'm not totally convinced about your other arguments either really. How often do we hear reports here of the *electronics* failing in any cordless tool, whatever the manufacturer? OK, the cheap ones may well wear out earlier mechanically and things like switches fail but I don't remember seeing many reports of failed chargers. (I think in the distant past I remember someone asking about a B&D charger, but that was so old it probably *was* of the "series resistor and nothing else" type).
Some clearly are, as you say, although the quality may be questionnable. I've certainly see fast chargers for cheap tools that have nothing much more than a rectifier and resistor.
How is the target customer who doesn't understand about electronics going to know?
Because if you buy a good quality tool with good quality (and more expensive) batteries to match from a manufacturer with a brand reputation, he is not going to risk that with a crappy charger.
However, the main points are the costs of the batteries - decent ones do cost good money - no way around that - that influence performance and longevity of the product.

OK, perhaps I wasn't completely clear. The point was really that cost cutting is done throughout and I have seen fast chargers having very limited electronics.
In chargers, probably not, because generally the batteries or mechanics fail first. Speed controllers certainly do, as do commutators and windings on motors.
There is a huge difference between the speed controllers on decent drills vs. the cheap generics. Try out a Makita or Metabo alongside a cheapie and you will see what I mean.

I don't know, did I say they would? :-)
I suspect the trend will be towards 'proper' fast chargers simply because of the cheapness of providing them. So buy a recent model.
This is also, strangely enough, a function of poor batteries. As I said, changing to decent ones made a big improvement on my PP 18 volt. The starting torque was far easier to adjust with good quality cells than with a brand new PP branded one.
I wonder how...
Perhaps it's lower internal resistance on the better packs?

That would be the logical assumption. Certainly, decent cells can supply considerably higher peak current than poor ones.
Bought a Bosch Psb 24ve2 Cordless Combi from ebay £90 inc delivery - New.

How is it that the link points to
