Use Wet for Finer Finish and Longer Abrasive Life
Achieve optimum results when you use this diamond abrasive sheet with a coolant. Coolant is a desirable component of diamond polishing, since it efficiently cools both the work and the abrasive. Beyond its coolant properties, the coolant will remove swarf and prolong abrasive life.

Recommended Applications
Quickly sand down concrete, granite, stone, glass, ceramics and carbides etc. Polish by hand with water for a better finish and to extend the life of the sheet.
