Are you looking for a new drill, but do you already have batteries at home which you can use? Or do you just want an extra drill, for example one with an impact function or with more power? It's more affordable to choose a drill without battery. These bare tools are more affordable than complete sets. In addition, all those extra batteries take up a lot of space. Make sure the battery you have at home is compatible with the drill of your choice. Ask yourself whether the battery is of the same brand as the drill, the voltage matches (12V or 18V), and whether they belong to the same battery platform.
