Metal Bond Concrete Grinding Plates for Prepmaster
Application:
Installed on Prepmaster systems and used for the general purpose of concrete floor or terrazzo surface grinding.
The metal bond diamonds are offered with one and two segments. Choosing between one or two segments allows the operator to control the grinding speed. Two-segment tools are designed for heavier machines, inches. Single-segment tools are designed for lighter machines, or where aggressive stock removal is required. We recommend using single-segment tools for the first step even with heavier machines for faster opening of the concrete.

We recommend you to choose right bond based on the PSI or MOH’s of concrete:
| BOND | XS | S | M | H | XH |
| MOH’S | 6-9 | 4-6 | 3-5 | 2-3 | 1-2 |
| PSI | 6-9,000 | 4-6,000 | 3-5,000 | 1.5-3,500 | 1-2,000 |
| MPA | C50-C65 | C35-C55 | C20-C40 | C15-C25 | C10-C20 |
| CONCRETE HARDNESS | EH | H | M | S | XS |
But it still depends on your true situation for bond choosing. We’d like to offer you a better solution if detailed information is available.
