MK Diamond 157115 3" Resin Wet Polishing Disc, Buff Black

Flexible, Hook & Loop backed polishing discs designed to achieve a scratch-free highly polished finish on all straight or contoured granite and marble edges. The Hook & Loop backing allows for fast disc changes.

Important: Resin Pad Brake-In ProcedureDiamond resin discs are shiny when new. This shine must disappear in order for the discs to perform their best. 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.
