Bosch’s new GSR 10.8 V-LI-2 cordless drill/driver (left) is half the size of a 12 V unit and weighs only 1.1 kg yet provides 100% power

Its two-speed gear box with 20+1 torque settings ensures good power transfer when screwdriving and drilling.

In first gear, the tool drives screws with diameters up to 7 mm. In second gear, it drills holes up to 19 mm in diameter at optimum speed in softwood. The 10 mm Auto-Lock drill chuck enables easy bit changes and allows a firm hold on the drill bit or screwdriver bit. The unit recharges gently in 30 minutes.
