Wickes have some massive reductions on their power tool ranges, upto 40% off, including the professional series, which like the Ryobi +one series, consists of 7 power tools that share the same battery type.Even the NiCad batteries are a very decent 18v 2.0AH so lots of power (remember it's not the voltage you're looking for, but the AH rating!).Over the years we've used quite a lot of Wickes stuff (kitchen fitting, UPVC Windows etc), which hold up very well, even better than some of the others we have such as Ryobi, Makita & DeWalt.Actually the DeWalts aren't as well made as they used to be, a lot of their cheap stuff is really only DIY quality, with very average batteries.
Here are some of the Wickes deals...
18v Cordless Nail Gun (Fires upto 35mm brads, dados etc) was £63.15 now £36.96
18v Cordless Circular Saw 140kmm blade was £67.99 now £39.84
18v 2.5AH Lithium Ion (li-ion) Battery was £88.59 now £51.86
There's a lot of other stuff reduced as well, well worth a look, I was in Aylesbury this morning, and they also had some chop / mitre saws, sabre saws etc
Obviously the pro stuff mostly comes without batteries, but as they share the same batteries it's economical, you can choose either Nicads or Lithium Ion.Nicads are fine, as long as you fully charge them, and then run them down fully before recharging.We found the best way was at the end of a day if drill hasn't run out (not very likely!), we tape the trigger in to run it out, and then leave on charge overnight, and they've lasted a good few years that way.If you only use it once in a while, just be sure to totally run it out at least once a month before recharging, and then you're batteries will last better.Obviously if you can afford it, then go for lithium batteries, which are much better.
Sorry if I've made any errors, I'm knackered with the heat!
