This kit is a valuable first piece or addition to anyone's tool collection. You need only to buy this and you will have an all-in-one system for making various home repairs and renovations that require drilling or driving fasteners. The drill driver has a keyless chuck that allows you to quickly switch bits and switch jobs quickly. The magnetic bit holder keeps everything in one place, making it easier on you, the diy-er or professional. The included battery is compatible with any of the Ryobi One+ tool system as well as backwards compatible with many of the Ryobi blue series of tools. It is quickly charged with the P118 charger, also included in this kit. Store everything neatly in the lime green Ryobi tool bag when you're finished with the job. It all fits snugly with room leftover for extra bits and pieces. Even if you already have a box for tools, it can act as a lunch box in a cinch. This is a versatile tool set that, when purchased together, makes for the smart, economical addition to anyone's collection, and the perfect entry point into the DIY universe.
