Professional diamond polishing discs, with the highest diamond concentration, are used to achieve a high-quality finish on straight or contoured edges. Their unique design allows for rapid and even removal rates with minimum effort. The center hole permits water lubrication during polishing operations. Hook & Loop backed for fast disc changes. These diamond discs are used for polishing granite, hard marble and porcelain. Should not be used on soft marble. Use grits in sequential order from 50 to buff.

Important Break-In Procedure
Diamond resin discs are shiny when new. This shine must disappear in order for the discs to perform their best, especially with the finer grits (400 and up). To do this, run any new disc on a rough surface - such as granite, sandstone or concrete - always making sure there is enough coolant (water). This will force the outer bond to be eroded, leaving the diamonds properly exposed for polishing. They will gradually perform even better as normal wear sets in.
