Our single head floor grinders are a great solution for removing a thin layer of concrete or prepping the surface for an epoxy coating. The units come with a 10" diamond disc that provides a smooth finish and allows for usage on expansion joints. The grinder can be used wet or dry and have a hookup for a garden hose if needed. The units also have a port where a shop vacuum can be used to help with dust control. Make and model may vary by location.
