This is the perfect drill driver for weekend projects. Relatively light-weight for extended use without tired arms, yet a full 14.4V battery for the torque you need for stubborn screws. Everything you need, including battery, charger, and 14 bits and tips. (See documentation.) Even pros can make use of this drill driver; keep a standby that is always charged for when the main drill goes walkabout, or a helper needs to use a drill, or when someone wants to borrow your drill, etc.
