Right – my real world advice!
The Worx stuff is very good for DIY. I used to work for Homebase and have tried loads of them. I don’t think they had quite the fine control of a Bosch DIY drill but the build quality was as good. You generally get 2 batteries which you don’t normally with Bosch. I think the Worx one would be better than a B+D one easily.
For all those folk telling him to spend loads on Makita etc, did you not notice the £50 budget requirement?
I used to advise people if they came in with a £100ish budget to buy a decent quality 12v cordless for screw driving tasks (I used a 12v Bosch for years and it never lacked power go screwdriving) and maybe £20-30 on a basic corded drill for drilling into brickwork. That would certainly be better than a £100 cordless only, which especially round here in W Yorks wouldn’t cope with drilling into stone.
Budget some money for quality drill bits and screwdriver bits too – I’d rather use high quality bits in a cheaper drill than the other way round every time.
The Bosch 12v one I had died last year (cost £50) and I bought a li-ion Bosch 18v cordless for £100, 3 day only offer from B and Q which I snapped up (2 batteries too!). Well worth the money as at the time you couldn’t buy them online for less that £140 with only 1 battery.
