When grinding a very hard surface like concrete you want a slow rotating grinding tool. Unlike cutting tools which are typically fast rotating and generate heat and debris, for grinding and polishing a slower speed is desired. With a variable speed angle grinder the speed of the rotating head can be changed from slow to fast.

Grinding aids are organic compounds that are added to the mill during cement grinding. Their main purpose is to reduce the energy required to grind the clinker into a given fineness. In addition, some products (usually referred to as performance enhancers) provide positive effect on cement hydration improving strength development [1].
