TUSK DIAMOND POLISHING PAD (with plastic backer): These premium quality diamond polishing pads feature a polishing pad and backer 'ALL-IN-ONE' design ready to be used on any angle grinder to polish a range of very hard materials into beautiful shiny pieces such as kitchen benchtops, concrete hearths, garden art, custom poured concrete vanities etc. Can be used WET or DRY which in most situations is a lot easier especially if a concrete hearth or benchtop has been poured in place, however, water makes a messy slurry that can be difficult to clean up and dry polishing is convenient but the dust needs to be managed. Either method gives the same finished result. The best control is achieved when using a variable speed angle grinder.
