Bosch is extending its 18 volt range for professionals and is introducing a cordless caulking gun to the market for the first time. The GCG 18V-600 Professional provides tradespeople with a nine-level speed setting to enable all common acrylics, silicones, adhesives and epoxy resins to be applied with exceptional control. In addition, the caulking gun is equipped with an accelerator switch, which provides additional control for finishing work. In order to apply viscous adhesives and sealants quickly, the GCG 18V-600 Professional has a push force of 3.5 kilonewton as well as a feed rate of 9 millimeters per second. The cordless caulking gun also has an automatic reverse function: When the user stops pressing the accelerator switch, no material leaks out afterwards. This enables builders of facades, windows and kitchens, tradespeople in the interior fitting or automotive sector, installers and sealing experts to work in a controlled, fast and clean manner. The cordless caulking gun is suited for both cartridges with a fill volume of up to 400 milliliters and foil bags of up to 600 milliliters. Both can be simply and conveniently changed in very few steps to suit a variety of different tasks.

Full compatibility with the existing 18 volt range

The GCG 18V-600 Professional is powered by high-performance 18 volt lithium-ion batteries which are part of Bosch’s “Flexible Power System”. Advantage for tradespeople: They can use their battery immediately without having to worry about whether it will fit. The “Flexible Power System” guarantees compatibility with all new and existing professional power tools and chargers within the same voltage class. This results in greater productivity in day-to-day work.

The GCG 18V-600 Professional will be available from September. All prices are recommended retail prices excluding VAT. Subject to change
