Concrete grinder - Wikipedia
A concrete grinder can come in many configurations, the most common being a hand-held angle grinder, but it may be a specialized tool for countertops or worktops. Angle grinders are small and mobile, and allow one to work on harder to reach areas and perform more precise work. There are also purpose-built floor grinders that are used for grinding and polishing marble, granite and concrete.
