Strauss Diamond’s DiaPol L26DMF Diamond Polisher is a knife shape diamond polishing system for use on all types of porcelain crowns and bridges. Also great for work on zirconia or alumina copings without heat generation, its new binding component, as well as the natural diamonds, allow for optimum polishing results. This allows the DiaPol L26DMF to achieve a very smooth surface without any polishing paste or an extra glaze firing.
