28mm DRYGRES Drill bit
The DRYGRES range of diamond drill bits are recommended for the drilling of all types of ceramic tiles, especially porcelain tiles, and other covering 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.
DRYGRES diamond drill bits are made for dry cutting and can be used, thanks to their connection with a M14 thread, directly with a grinder or non-percussive power drill, by using the drill adaptor.
The average life of the 50mm DRYGRES drill bit is typically about 60 holes, this is dependant on the type of material, its thickness, proper cooling and use.
The drilling depth of DRYGRES drill bits is 36mm.
