It's arrived.
It's in what I believe is called a 'Retail Pack', that is it's meant to be hung up.
As predicted there's no instructions and no Guarantee, although the usual Sale and Supply of Goods Acts apply.
The gears feel 'orrible, but more about that later.
By way of a test I used a 16mm flat bit to drill through a couple of inches of softwood using a battery drill, which it coped with OK, although clearly it's wise not to push too hard.
So, what's in there? As expected there's a couple of bevel gears which look to be cast. Involute they ain't, more like semicircles. Each shaft is supported by a machined bush which has a flange to locate it in the (plastic) body. There's a token amount of grease applied. The chuck looks to be quite good quality and at least it has a key. It's threaded 3/8" x 24 and there's a LH Thread screw to stop it coming off when you reverse direction – all very normal. The gears appear to be pressed and staked on to the shafts.
Now for the oddity; there's no provision for adjusting the end float on the shafts and no method of resisting thrust, so that when you push on the drill you actually force the gears together, hence the horrible feel. The reason I find this odd is that behind each shaft is an indentation in the moulding where you might expect there to be a thrust pad. I'll see what I can do.
