Featuring a metal chuck and hammer drill mode, the 24V drill is made for the serious do-it-yourselfer looking to tackle any and all projects in and around the house. The hammer function allows you to drill holes faster through concrete and brick. Bit slippage problems are reduced with the metal chuck which provides superior gripping force for tough jobs. With 25% more run time, the 24V drill will drive over 400 screws on a single charge. The 2 speed gear box allows for high torque driving in low gear and high speed drilling in high gear. The 24V FireStorm battery is a spring-loaded pack, which springs forward like a cassette with the push of a button, and then easily slides off. The FS2400D-2 includes the drill, two batteries, dual port charger, 2-#2 phillips bits, and a rugged storage case.
