Cordless Drywall Screwdriver GTB 18V-45. The GTB 18V-45 Professional cordless drywall screwdriver features a PowerSAVE mode, a brushless motor, and a retractable depth stop for maximum user comfort. To enable quieter operation, the motor in PowerSAVE mode is automatically activated only when the screw touches the wall. This significantly extends the runtime and increases the number of screws per battery charge compared to when PowerSAVE mode is off. For fast and effortless work, the depth stop is retractable and does not need to be removed to loosen screws; the depth setting remains unchanged. Its slim design and lightweight of less than 1 kg ensure excellent handling. The GTB 18V-45 Professional is designed for driving drywall screws with a diameter of up to 6 mm. It is compatible with all Bosch Professional 18V batteries and chargers (Professional 18V System) and with Bosch Professional magazine attachments for drywall screwdrivers. It is equipped with Electronic Motor Protection (EMP), a motor brake, a lock switch, a belt clip, and forward/reverse operation. Includes 2 x ProCORE18V 4.0Ah batteries; GAL 18V-40 Professional fast charger; L-BOXX 136; 1 x screwdriver bit (Bit) Ph 2; 1 x belt clip; 1 x bit holder.
