Bosch GSB 18V-28 18v Dynamic Cordless Combi Drill
The Bosch GSB 18V-28 is an 18V cordless combi drill designed for professional tradespeople requiring reliable performance across drilling and screwdriving applications.
Delivering 63 Nm of hard torque, this combi drill handles drilling in wood up to 38 mm diameter, steel up to 13 mm, and masonry up to 13 mm via its impact drilling function. The 13 mm full-metal chuck offers durability and reduced wear over extended use, accepting bits from 1.5 mm upwards.
The two-speed gearbox spans 0–500 rpm in first gear and 0–1,900 rpm in second, giving you the control to switch between precision screwdriving and faster drilling as the task demands. With five torque settings (3 standard plus 2 additional) and an Autolock chuck, it suits a wide range of fixing and drilling tasks on site.
Ideal for electricians, plumbers, joiners, and metal construction work, the GSB 18V-28 is compatible with all Bosch Professional 18V batteries and chargers, and also supports AMPShare for cross-brand battery compatibility. Electronic Cell Protection safeguards the battery against overload and deep discharge. Supplied in an L-BOXX 136 — battery and charger sold separately.

Battery AH Explained
The best way to describe battery amp hour is that this is effectively the size of your fuel tank, the more amp hours your battery has then the longer the battery will last between charges. More amp hours does not increase the power of a given tool.
Battery Voltage Explained
A tool with a higher voltage than another is a bit like choosing an engine in a car, the higher voltage will generally mean higher power & performance. As with cars though a bigger engine does not always translate to better performance so it is important to compare the specifications of tools at different voltages between different manufacturers.
