The Bosch GTB 18V-45 Professional is a battery-powered power screwdriver designed for fast fastening and light assembly work. With a compact pistol handle, a 1/4" chuck and a maximum idle speed of 4500 RPM, this 18V tool delivers responsive performance for repetitive screwing tasks. The tool provides up to 32 N⋅m torque in soft mode and 6 N⋅m in hard mode, and includes a built-in light and reversible rotation to support accurate operation in confined or low-light areas.

Advantages

The pistol handle design improves ergonomics and control during extended use while keeping the tool compact and maneuverable. High idle speed of 4500 RPM enables fast screw driving and reduces cycle time for assembly tasks. The built-in light illuminates the work area and the reversible function adds flexibility for both installation and removal of fasteners. Lightweight construction at approximately 0.95 kg reduces operator fatigue without sacrificing durability.

How to use

Install a compatible 1/4" bit into the chuck and secure it according to the manufacturer's instructions. Select the appropriate torque setting for the material and fastener type, then choose forward or reverse rotation as required. Position the tool on the fastener, depress the trigger to reach the required speed, and allow the built-in light to aid accurate alignment in dim areas. After use, switch off the tool, remove the bit if necessary and store the screwdriver with the battery removed or according to battery storage guidelines.

Recommendations

For best results use Bosch-recommended 18V batteries to ensure consistent power delivery and runtime. Match torque settings to the screw size and material to avoid overdriving. Use short, correct-fit bits to minimize wobble and ensure efficient power transfer. Regularly inspect and clean the chuck and ventilation slots, and follow battery care instructions to prolong tool life.
