The DRYGRES range of diamond drill bits are recommended for drilling of all types of ceramic tiles, especially porcelain tiles, and other wall materials such as marble and granite.
In the DRYGRES range of drill bits, RUBI has used VACUUM BRAZED technology, which increases resistance to temperature and friction, to fix the diamond particles in the cutting area.
