Bosch GWS 18V-11 S 18v Cordless Variable Speed Angle Grinder 125mm
The Bosch GWS 18V-11 S is an 18V cordless angle grinder delivering 1,100W of equivalent corded power across a versatile 125mm disc, designed for light-to-medium cutting and grinding tasks on site.
Built for MRO and final onsite installation work, this grinder handles a broad range of demanding applications including deburring, rust removal, line maintenance, and general repairs. Its optimised overload capacity ensures consistent performance and outstanding durability under sustained use.
A six-speed dial wheel allows precise control across different materials, making it equally suited to grinding steel, cutting masonry, and surface preparation work. The variable speed range of 3,000–9,000 rpm gives tradespeople the flexibility to match the tool's output to the task at hand.
User comfort is addressed through an anti-vibration auxiliary handle and a slimmer, longer grip profile, both designed to reduce fatigue during extended use. A full suite of integrated safety features further lowers the risk of injury during operation.

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.
