The DRYGRES kits are the most economical solution for those users who need to drill, dry, of different diameters, in any type of ceramic tile. The range of DRYGRES diamond drills are recommended for the drilling of all types of ceramic tile, especially porcelain stoneware, and other coating materials such as marble and granite. In the range of DRYGRES drills, RUBI has used the vacuum welding technology VACUUM BRAZED, which increases the resistance to temperature and friction, to fix the diamond particles to the cutting area. The DRYGRES kits have been designed, mainly thinking, so that the ceramic tile setter can obtain the best results when it comes to making the necessary perforations for water inlets, drains, light points, etc. DRYGRES diamond drills are dry cutting and can be used, thanks to its connection with M14 thread, directly with a grinder or electric drill without hammer, by using the drill adapter (ref 05976). The average life of DRYGRES drills 20 to 75 mm is 60 holes. The average life of the drills depends, ALWAYS, on the type of material, its thickness and the correct cooling and use. The drilling depth of DRYGRES drills is 36 mm. DRYGRES drills have a lateral opening that improves the cooling of the bit and facilitates the elimination of solid waste after each drilling. Before making a new perforation, we must make sure that the bit is clean and free of any obstruction. The maximum speed of use for DRYGRES diamond drills is between 14000 r.p.m. For a better finish and longer life of the bit, it is important to respect the proper turning speed and perform a slight orbital movement while drilling.
