The Bosch GSB 18V-55 cordless drill is one of the above-average devices in almost all monitored parameters. With a battery voltage of 18 V, the drill can handle demanding applications. The capacity of the 4 Ah battery is one of the higher ones and provides enough power for longer work. A second battery is also included. Charging the battery in 45 minutes is not the fastest in our test, but it is still among the above-average values. A great feature is the low weight of this model, namely 1 kg without a battery. This cordless drill fits both in the workshop of a do-it-yourselfer and in a professional suitcase.
The maximum diameter of a hole drilled in wood is slightly below 35 mm. On the contrary, thanks to the larger chuck size, it is possible to drill a hole with a diameter of up to 13 mm in the steel. A torque of 55 Nm is sufficient for all typical applications. The impact function allows you to drill holes in complex masonry, which can be described as a clear benefit. However, the performance of the cordless drill cannot be compared with the version of the cable model. Reverse and smooth speed adjustment allow easy work with the device.
