Cordless drill/driver. Which one should I get?

Ooooh - that's clever. How does it "know" when the screw is tight? And what of screws that are tight to screw in?

Seems I really have been missing out
The drill has a torque setting to stop the screw/head of the bit from rounding off

Thank you very much everybody for all your helpful advice. I have ordered a Ryobi RCD1802M Compact drill driver, a couple of batteries and a charger. The compact size should be quite nifty when drilling holes in joists and other confined spaces, the max. speed is 1600rpm, and it has a 13mm chuck. It was a bit less than £140 all-up. If it lasts as long as my old Hitachi, I won't ever need to buy another!

Now you're well screwed, Martin. Here's a spare chuck for you...

Make sure you keep the teeth in your chuck clean.
 
Just looking again at the photo I posted earlier this morning...what is all that left ear action? Has he been hit by a Rampant Ryobi? :ohmy:

Quite a timely thread for me ... I recently spotted an electric screwdriver at the local flea market and got it for £7. (The stallholder's pal laughed when I agreed to pay that price and said I could have got it for £5-6 if I had haggled!)

It had a Philips bit and I had a big box of Philips screws which I was using to fix some plasterboard up. I knackered the bit within about 10 screws so I have decided to go Posidriv from now on. I found a company on eBay doing a bag of 10 PZ bits for a few pounds so I'll give them a go. They might turn out to be cheap rubbish but it seemed worth a punt.

I hadn't realised that there is actually a significant difference between the 2 types of head until now which is a bit odd (sorry for the pun!) given that I worked for several years in a factory and averaged about 1,500 screw insertions a day using a compressed air-powered screwdriver. I can't remember which type we used, but suspect that they were PZ because it was very rare for the bits to slip. We only had problems with snapping the heads off after the company buyer tried to save money by buying crappy unbranded screws in bulk rather than the quality GKN screws that we normally used.
 
It's the angle of the photo. He's not quite straight on.

That said, most peoples' faces are symmetrical and most people will have one ear bigger than the other.
You get the Noddys for those sort of obs. Doc. :smile:
I don't see eye to eye with myself very often so 'symmetry' is out for me - even when I'm using my Makita. you know the drill - pull the trigger, bore your way through and you'll not see my ears for dust...

As far as screws are concerned, I recommend Ulrich screws.(I last bought some in Jan.) They are difficult to use but a strong Arm will beat them, hands down.
Anyway, I think most of us have 'fluctuating assymmetry' - as in fluctu Slomotion...what a time waster!

Though pozis are decidedly better,what really matters is pozi drivers for pozi, phillips for phillips. Also cheap crapy drivers of either pursuasion are the devil's work and should be binned

Yes - it turned out that I used a PZ bit on PH screws!

The used screwdriver had enough torque to get the screws in. I'm not sure how long its batteries would last because the bit wore out before I could do much work with it. I suspect that they will be running low on capacity because the tool appears to be 11 years old. (It has a sticker on it implying that it was made in 2004.)

And "Twinfast" & "Superdrive"?
you got me googling to double check, but twinfast is a supposedly superior woodscrew thread so not relevant to the screwdriver question, but superdriv is a slighly improved posidriv and apparently the screwdrivers are interchangable.

There are lots of others - a frearson - superficially like a phillips - but of course, imcompatible.

Apparently phillips were actually meant not to be over-strong so you would do less damage if you bollocked em up too tight - the screw would fail rather than damaging the job (aircraft). Not so clever if you're trying to undo an old rusty one, made of that special alloy made of cheese and soft iron that is quite popular
