RUBI has a kit of four DRYGRES 4DRILL dry-cut diamond bits with a practical case-case made of transparent plastic with a four-color belt ideal for transport and care, extending the life of product use.

The DRYGRES 4DRILL MINI KIT 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 BRAZED vacuum welding technology, which increases resistance to temperature and friction, to fix diamond particles to the cutting area. The DRYGRES 4DRILL MINI KIT, contains 4 drill bits of diameters Ø 6, 8, 10 and 12 mm, ideal for placing bathroom accessories or any type of decoration accessory on ceramic surfaces.

The drills of the MINI DRYGRES 4DRILL KIT are designed to be used exclusively with either a cordless drill or 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 the diameters of 6, 8 and 10 mm, and 40 mm deep for the 12 mm diameter drill bit. All the bits of the DRYGRES 4DRILL MINI KIT 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,
