Bosch GSB 120-LI 12V Cordless Combi Drill, 30Nm, 10mm Chuck

Bosch GSB 120-LI Combi

The Bosch GSB 120-LI Drill provides professional-grade versatility for tradespeople requiring a single, compact tool for screwdriving, drilling, and impact drilling applications. This 12V unit bridges the gap between lightweight drivers and heavy-duty hammer drills by utilizing a robust planetary gearbox to manage diverse torque requirements across various materials. It is engineered for durability and high flexibility on busy jobsites.

Built for the Job

This combi tool is a staple for second-fix carpenters, electricians, and facility maintenance engineers. Its compact head length makes it highly suitable for working in confined spaces such as cabinet interiors, between floor joists, or inside electrical panels. The hammer action allows for reliable masonry drilling up to 8mm, which is essential for mounting brackets, conduit clips, or light fixtures. Contractors value this model for its balance of weight and power during repetitive overhead tasks where larger 18V tools cause user fatigue.

• Kitchen and cabinetry installation involving both wood and metal fixings.

• Electrical box mounting and securing conduit to brick or blockwork.

• General maintenance and assembly tasks in commercial or residential settings.
