Bosch GSB 12V-15 Professional Cordless Impact Drill Driver, 2 x 2 ampere-hours, Blue / Black

The Bosch GSB 12V-15 Professional Cordless Impact Drill Driver, 2 x 2 Ah is a battery-powered hammer drill for drilling, impact drilling, and screwdriving. Its 12 V supply places it within the Bosch Professional 12 V system. Maximum torque is rated at 30 N·m for hard applications and 15 N·m for softer applications. Maximum drilling diameter is 19 mm in wood, 10 mm in steel, and 10 mm in concrete. It can also drill brickwork up to 10 mm.

The pistol-grip design is suited to confined spaces and overhead positions. A keyless chuck accepts bits from 1 to 10 mm and allows tool-free bit changes. The two-speed gearbox and adjustable speed control provide separate ranges for controlled fastening and drilling. Power comes from removable lithium-ion batteries, with two 2 Ah batteries and a charger supplied. A carrying case and a 25-piece drill-bit set are also included for storage and common drilling tasks.
