A useful home toolkit is smaller than most starter bundles and stronger on repeat-use tools like a drill, tape measure, screwdrivers, pliers, level, and basic safety gear.
Most households should buy a cordless drill first, because it covers drilling and light screw driving, while an impact driver becomes useful later for long screws and tougher fastening.
The most useful screwdriver knowledge is matching the driver shape to the screw head correctly so the tool seats fully and does not strip the fastener under pressure.
