Designed to cut tiles, the disc has continuous rims to reduce chipping, but with the hardest tiles even this is not always enough. The EXPERT HardCeramic tile disc is Bosch’s top performance diamond disc for hard tiles. Thanks to a series of technologies and design features it makes the cleanest cuts. In thicker tiles and stone slabs (over 10 mm), using a wet cutter and a designated tile blade will give you the best results.
