Because this is an impact drill, the additional torque makes it particularly suited for screwdriving. Ideal for drilling into wood, metal, concrete or plastics. It’s lightweight, handy and ergonomically designed with a lithium-ion battery for longer use. It features a variable speed setting for precise control with a keyless 3/8-inch (0.8 - 10mm) chuck. All standard size bits are compatible with the 10mm keyless chuck. Plus, it comes with an additional backup battery and handy carry/storage case.
