Rubi kit with TCR saw blade and drygres drills | incl. case - 68923

The Rubi Kit with TCR saw blade and DRYGRES drills is the most economical option for using different sizes of dry drills. Special features DRYGRES diamond drills are made for dry drilling and can be used via M14 thread connection on a grinding machine or by means of a drill adapter (ref. 05.976) on a drill. The average lifespan depends on the diameter. In diameters of 6-12 mm the average life expectancy is 25 holes and the DRYGRES 20-75 mm has an average life expectancy of 60 holes. The average lifespan of the drills always depends on the type of material, the thickness, proper cooling and the application. The drilling depth is 36 mm. The diameters of 6, 8, 10 and 12 mm contain wax inside. This wax melts during drilling and this promotes cooling and the removal of drilling residues from the drill head. Once the wax has run out, the drill can be used as normal. Only wear of the diamond on the drill bit can determine when the drill bit is worn out. The drills (diameter 20-75 mm) have a side opening that improves the cooling of the drill and this also ensures that the remains can be more easily removed from the drill after drilling. Before the drill is used again, all residues must be removed from the drill bit. The maximum speed 14,000 rpm For a better finish and longer drill life, it is important to maintain the recommended rotation speed and to make a rotating movement with the drill while drilling. The set is the most economical option for using different sizes of dry drill bits. The series of diamond drills are recommended for drilling all types of tiles and other wall or floor materials such as marble and granite. In the diamond drill series, RUBI has used vacuum brazed technology, which increases resistance to temperature and friction, thus increasing the lifespan of the diamond drill.
