Bosch GTB 650 Professional
The Bosch GTB 650 Screwdriver is a high-speed corded power tool engineered for efficient drywall installation in commercial and residential construction. This professional-grade unit features a 650W motor optimized for driving screws into gypsum boards and metal or timber studwork. It provides the high RPM necessary for self-drilling fasteners to penetrate light-gauge steel framing without stalling or stripping threads.
Built for the Job
Contractors and interior fit-out specialists require speed and depth consistency when boarding large surface areas. This tool addresses those needs with a specialized depth-stop mechanism that ensures every fastener sits flush with the board surface. The high rotation speed of 5,000 RPM allows for rapid progress during high-volume repetitive tasks. Because the unit weighs only 1.4kg, it reduces operator fatigue during overhead ceiling installations or long shifts on vertical partitions. The ergonomic barrel grip allows for a straight-line power transmission from the operator’s arm to the screw head, improving accuracy and reducing the risk of cam-out.
