Bosch are making some waves this year, putting out some seriously premium 18v tools. Most importantly they have released their CORE batteries with greatly increased power ouput, enabling a host of more powerful 18v tools. These include their incredible new sabre saw GSA18V-125K, their 1″ Bulldog SDS GHB18V-26K and now their first brushless grinder, the GWS18V-125SC (note that is the European model number, may not be same in the US when released). Bosch claim it has the power of a 1,000W electric grinder when paired with a CORE battery!
The GWS 18-125 SC is the ‘connected’ model, which is Bosch’s bluetooth tool control system. It allows users to alter settings like startup speed and the LED light, and also shows usage statistics. It is controllable via the Bosch Toolbox app, and works perfectly. It updates almost instantaneously and is completely intuitive. The model without the connected capability is unsurprisingly designated the GWS 18-125 S.
