How much will a concrete grinder remove? Concrete grinders vary in depth-of-grind depending on their size and how many heads the grinder has. Double-head grinders will remove more material in a single revolution compared to single-head grinders. Walk-behind concrete grinders will remove more material than handheld grinders.
