Cordless Power Tools

Buy into one battery, and every tool after the first gets cheaper.

That's the single most useful thing anyone can tell you before you start buying cordless. Most of this range runs on the same 21V packs, so your second tool arrives with spare batteries for your first, and your third means you never wait for a charger again. It matters far more over five years than any individual spec on any individual tool.

Start with the drill and impact driver kit if you own nothing — between them they cover most of what a homeowner ever needs to do. Add the wrench when a lug nut beats you, and the saws when the job moves outdoors.
