The bush hammer tool is a powerful construction tool designed for working stone and concrete. Processing can be carried out both for decorative purposes and for technical purposes. In the first case, it is to give roughness to smooth surfaces of tiles, granite, ceramics. For example, so that the steps were not slippery. In the second case, it is the preparation of the concrete surface for tile laying, knocking down buildup on concrete castings, creating an adhesive surface before further processing. The bush hammer tool, in some cases, is used to remove rust from metal or old paint. This attachment allows you to create an electric bush hammer from a Bulgarian drill. Such a tool is easier and more convenient to work, and most importantly effective because at the same time you can do much more work than if you use a mechanical tool and your own strength. The diameter of the disk is 150 mm, there are 4 rollers with spikes on the surface.
