These resin diamond segments are used with water for polishing Marble, Limestone and Terrazzo.
They are not exact grades only approximate, because of this less steps are needed to polish the stone. On most marbles only 2 grades are needed (green then yellow) to reach an approximate grade of 400 and then to proceed with crystallisation for a high shine, (3 grades on darker/harder marbles).
Velcro back for use with a Velcro Drive Board on floor machines.
Professional use only.
