Got a new18v battery powered hammer drill. Two battery packs, one-hour charger and so on. Cheap but much better than the 9.6v toy I had – it could do a few minutes of screw-driving into wood and then needed a five-hour recharge of its sole battery pack. I also got a set of masonry drills since I’m putting a can crusher on the kitchen wall.
After I charged up both batteries of the new drill I used it to drill holes in masonry, drive in screws into masonry and then drive some screws into wood for fitting a latch to keep Pip out of the bathroom. First battery still full of energy!
