Within its range of diamond drills for dry cutting, RUBI has DRYGRES 4DRILL bits. The DRYGRES 4DRILL diamond drill range is recommended for drilling all types of ceramic tile, especially porcelain stoneware, and other tiling materials such as marble and granite. In the DRYGRES 4DRILL drill range, RUBI has used vacuum welding technology, VACUUM BRAZED, which increases resistance to temperature and friction, to fix diamond particles to the cutting area. DRYGRES 4DRILL bits are perfect for placing bathroom accessories or any type of decoration accessory on ceramic surfaces and / or natural stone.DRYGRES 4DRILL diamond drill bits are designed to be used exclusively with either a cordless drill onr an electric drill. Their hexagonal connection allows them to adapt quickly to drills with a 13 mm chuck.The drilling depth of the DRYGRES 4DRILL bits is 36 mm. for diameters of 6, 8 and 10 mm, and 40 mm deep for drill bits of diameter 12, 14 and 20 mm. All DRYGRES 4DRILL bits contain wax inside. This wax melts during the use of the drill and facilitates the cooling and evacuation of the remains of the drilling (If the wax runs out, the drill can continue working. Only the total loss of the diamond indicates the end of the life of the drill.).Being dry cut, it is necessary, for proper cooling of the drill, make a slight orbital and constant movement during drilling, as well as eliminate any remaining material, between drilling holes.DRYGRES 4DRILL drills, from RUBI, have a system that blocks the loss of that wax from the back of the drill, thus concentrating the wax, always on the tip and ensuring lubrication during drilling.The minimum recommended speed of use for DRYGRES 4DRILL diamond drill bits is 1000 rpm. For a better finish and longer duration of the drill, it is important to respect the proper turning speed and perform a slight orbital movement during drilling, as well as make sure that once the hole is finished there are no remains of the perforated material inside the drill.
