"DRYGRES Ø8 mm Core Drill on RUBI Grinder - 5989"

The DRYGRES diamond core drill range is recommended for drilling all types of ceramic tiles, particularly porcelain stoneware, and other covering materials such as marble and granite. In its DRYGRES core drill range, RUBI has utilized VACUUM BRAZED technology, which increases resistance to temperature and friction, to bond the diamond particles to the cutting area. The DRYGRES core drills, with diameters ranging from 6 to 12 mm, are perfect for installing bathroom accessories or any other type of decorative accessories on ceramic surfaces. The other diameters in the EASYGRES diamond core drill range, from 20 to 75 mm, have been designed primarily for tile installation professionals to achieve the best results when it comes to making drill holes for water outlets, drains, light points, etc. The DRYGRES diamond core drills are intended for dry cutting and, thanks to their connection with the M14 screw, can be used directly with a grinder or a non-hammer electric drill, provided that the drill adapter (ref. 05976) is used. The average lifespan of the DRYGRES core drills varies according to diameter. For DRYGRES core drills with diameters of 6 to 12 mm, the average lifespan is 25 holes, and for those with diameters of 20 to 75 mm, their average lifespan is 60 holes. The average lifespan of the core drills ALWAYS depends on the type of material, its thickness, as well as its proper cooling and use. The drilling depth of the DRYGRES core drills is 36 mm. For diameters of 6, 8, 10, and 12 mm, the DRYGRES core drills contain wax inside. This wax melts during the use of the core drill and facilitates cooling and the removal of debris from the drilling process (If the wax runs out, the core drill can continue to work. Only the total loss of the diamond indicates the end of its lifespan).
