Soft bond, hard bond and segment count
MK explains that hard bond grinding heads are for green concrete and asphalt, while soft bond heads are for cured concrete. Very hard material wears the metal bond away quickly enough to keep exposing fresh diamond, which is why the soft bond is the right match for old or cured slabs. In general, fewer segments concentrate the machine's weight for faster stock removal and more segments spread it for a finer, longer-wearing cut; this head has 20 segments, and the MK-1010S is the sister model with 10 segments.
