Rubi 5927 12mm Dry Diamond Drill Bit Hex Shank Wax filled
Rubi 5927 Dry Diamond Drill Bit Hex Shank is filled with wax and measuring 12mm. The DRYGRES 4DRILL dry cut diamond bits are wax filled. So, ideal for drilling in ceramic tiles, porcelain, granite, and marble. Also, resistant to friction and temperatures thanks to VACUUM BRAZED welding technology. Perfect diamond drill bits for placing bathroom accessories and decorations on delicate ceramic surfaces.
Also, the DRYGRES 4DRILL has a drilling depth of 36 mm for diameters 6, 8, and 10 mm, and 40 mm for diameters 12, 14, and 20 mm. So, there is wax inside all DRYGRES 4DRILL burs.
So, the wax melts once the drill bit is in use, which aids with cooling and debris removal. Finally, the drill can continue to work after the wax has run out. Only total diamond wear signifies the end of the drill life.
