The range of bits in the MINI DRYGRES kit are recommended for drilling all types of ceramic tiles, especially porcelain stoneware, and other covering materials such as marble and granite.

In the MINI DRYGRES kit bits, RUBI has used VACUUM BRAZED vacuum welding technology, which increases resistance to temperature and friction, to fix the diamond particles to the cutting area.

The bits in the MINI DRYGRES kit are perfect for placing bathroom accessories or any type of decoration accessory on ceramic surfaces.

DRYGRES diamond drill bits are dry cutting and can be used, thanks to their M14 thread connection, directly with a grinder or with a hammerless electric drill, by using the drill adapter (ref. 05976).

The average life of the bits in the MINI DRYGRES kit (from Ø 6 to 12 mm) is 25 holes. The average life of drill bits ALWAYS depends on the type of material, its thickness and correct cooling and use.

The drilling depth of DRYGRES drill bits is 36 mm.

The bits in the MINI DRYGRES kit contain wax inside. This wax melts during use of the drill bit and facilitates cooling and evacuation of drilling debris. Before performing a new drilling we must make sure that there are no ceramic remains left in the solidified wax inside the drill bit.

If the wax runs out, the drill bit can continue working. Only complete loss of diamond indicates the end of the bit's life.

The maximum speed of use for DRYGRES diamond drill bits is between 14000 r.p.m. For a better finish and longer life of the drill bit, it is important to respect the appropriate rotation speed and make a slight orbital movement during drilling.
