The GTB 18V-45 Professional cordless drywall screwdriver comes with PowerSAVE mode, brushless motor, and retractable depth stop, offering maximum ease of use. For a silent job, the motor will be activated automatically as soon as the screw touches the wall when PowerSAVE mode is switched on. This significantly extends the runtime and increases the number of screws per battery charge, compared to a switched off PowerSAVE mode. For fast and easy working, its retractable depth stop eliminates the need to remove the depth stop for unscrewing the screws by keeping depth setting unchanged. Its slim shape and less than 1 kg weight ensure excellent handling.The GTB 18V-45 Professional is designed for fastening drywall screws up to 6 mm. It is compatible with all Bosch Professional 18 V batteries and chargers (Professional 18V System) as well as with Bosch Professional screw gun magazine attachments.
