I bought a DeWalt DCD795, with a 1.5AHr battery, for £99 from Wickes a year or so ago. I’ve found it to be excellent so far, and no problems with battery life, although if you’re doing loads of work, then perhaps a higher capacity battery would suit better. The hammer function isn’t bad for a cordless; if you need more power for doing lots of drilling into concrete,masonry etc, then a decent corded drill will be a better bet anyway. But basically, anything from the main manufacturers such as Bosch, DeWalt, Makita etc will be fine. Things like spare batteries will be easier to find from those three. A ‘brushless’ drill will offer higher torque and efficiency for a given power rating.
What chance any deals landing this bank holiday?
I’ve not seen so many good deals on BHs, since CV kicked in, probably because demand for tools for DIY etc is a lot higher at the moment, plus supplies are problematic cos of brexit etc. Best is to Google for reviews, then try to find a good deal on something that you like that gets good ratings really.
