Bosch GSB 18V-90 C -iskuruuvinväännin, 2100 kierr./min, 36 N⋅m vääntömomentti

The Bosch GSB 18V-90 C impact driver combines a compact, pistol-handle design with a powerful 18V battery system and 4Ah capacity to support extended work periods. With a maximum idle speed of 2100 RPM and a soft-application torque rating of 36 N⋅m, this cordless impact driver is built for general fastening, drilling in soft materials and repetitive assembly tasks. The tool's dimensions (77 mm width, 175 mm depth, 210 mm height) and lightweight construction provide balanced handling during prolonged operation. The kit includes two batteries to reduce downtime and maintain workflow.

Advantages

The compact housing and pistol-handle ergonomics enable comfortable one-handed use and improved access in tight spaces. Battery power allows cordless mobility and eliminates the need for a power outlet on the job. The rated idle speed up to 2100 RPM provides sufficient rotation for a range of soft-material applications, while the 36 N⋅m torque is suited to controlled fastening tasks. The inclusion of two batteries supports continuous operation by enabling quick battery swaps.

Suitable for

• Fastening screws and bolts in wood, drywall and light metal
• Light drilling and impact-assisted driving in soft building materials

How to use

Install a compatible 18V battery and select the appropriate bit for the screw or drill application. Use the pistol-handle grip to position the driver firmly against the work surface, then apply steady pressure while operating the trigger to control speed. For repetitive fastening, remove and inspect bits periodically to maintain efficiency. Change batteries as needed to maintain consistent performance and follow the manufacturer’s charging instructions for the included batteries.

Recommendations

For best results, use the driver with recommended Bosch 18V batteries and appropriate bits for the material. Start at lower speed to align fasteners, then increase speed as needed. Wear suitable eye and hand protection, and allow batteries to cool between heavy-duty cycles to prolong battery life.
