RYOBI 18V One+ introduces lithium-ion performance at Ni-Cd prices. This kit is powered by new and improved lithium-ion batteries, the very best value in lithium-ion performance. They hold a charge 4X longer, offer up to 20% more runtime and are 45% lighter weight than Ni-Cd batteries. Best of all, like all 18V One+ batteries, these new lithium-ion batteries work in every RYOBI 18V One+ tool ever made. Batteries stored on the IntelliPort charger are conditioned for peak performance. The drill includes a 1/2 inch heavy-duty single sleeve, keyless chuck with a 24 position clutch to match your drilling and driving needs. The drill features the exclusive MagTray and on-board bit storage, which allow convenient placement of bits and screws.
