This Metabo HPT MultiVolt 1/2" 36 V hammer drill kit offers many benefits for everyday tasks on the jobsite. The hammer drill includes a 36 V brushless motor for uncompromising performance, a durable aluminum housing, an all-metal gear system and a 1/2" keyless metal chuck with carbide inserts for quick and easy bit replacement and secure holding power. Reactive Force Control (RFC) senses tool overload and stops rotation to ensure user safety and protect the tool motor and battery. Equipped with AC/DC convenience, the tool can be powered by a MultiVolt battery or a MultiVolt AC adapter (sold separately). Metabo HPT batteries deliver more than 1440 watts of power, which is similar to 120 V-15 A corded power tools. This means that you enjoy greater power and approximately 46% more capacity than standard batteries. This set includes a belt hook, built-in LED light, 2 x 4.0 AH 36 V lithium-ion batteries, a charger and a storage case.
