The Bosch GTB18V-45B15-RT 18V Brushless Screwgun is designed to get the job done comfortably and fast. This light, compact screwgun features a well-balanced ergonomic grip ideal for comfortably holding the tool, allowing the thumb and the index finger to control the operation. Xtend Drive is an intelligent lock-on mode that activates the motor only when the bit senses pressure, increasing runtime. The tool remains operational but is quiet between screw activations. The screwgun features a retractable depth gauge, so the user doesn't have to remove the cone on the tool to reverse out a screw. The tool delivers 4,500 max rpm to drive drywall screws into sheet rock, gypsum board and metal or wood studs. The kit includes a next-gen CORE18V 4 Ah Advanced Power Battery, which delivers 2x the runtime compared to previous generation BAT612 2 Ah battery. This tool is manufactured refurbished. Items in Kit may vary.
