UltraBerry 26 x 2mm KnifeEdge wheel Coarse plus (extra coarse for when a little extra material needs to be taken down, this will get the job done!) RedBerry, BlueBerry, GoldenBerry, and the new UltraBerry instruments are suitable for contouring zirconia and lithium disilicate restorative materials. Berrys contain a high concentration of uniquely shaped diamond particles. Berrys effectively contour and shape of these materials.
The “Berrys” reduce heat transfer, prevent microscopic surface scratches, and leave a smooth surface during the contouring process. This smooth surface eliminates the capillary effect which causes stains in unwanted areas.
