The DRYGRES range of diamond drill bits is recommended for drilling all types of ceramic tiles, especially porcelain stoneware, and other cladding materials such as marble and granite.
In the DRYGRES range of drill bits, VACUUM BRAZED vacuum welding technology, which increases temperature and friction resistance, has RUBI used to fix the diamond particles to the cutting area.
DRYGRES drill bits, with diameters Ø 6 to 12 mm, are perfect for placing bathroom accessories or any type of furnishing accessory on ceramic surfaces. The rest of the diameters of the DRYGRES diamond drill bit range, from Ø 20 to 75 mm, have been designed mainly so that the ceramic tile fixer can obtain the best results when making the necessary perforations for water intakes, drains, light points, etc.
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 DRYGRES drill bits varies according to the diameter: in Ø 6 to 12 mm the average life is 25 holes and in DRYGRES drills from Ø 20 to 75 mm the average life is 60 holes.
The average life of drill bits ALWAYS depends on the type of material, its thickness and the correct cooling and use.
The drilling depth of DRYGRES drill bits is 36 mm.
In diameters Ø 6, 8, 10 and 12 mm, DRYGRES contains wax inside. This wax melts during the use of the drill bit and facilitates the cooling and evacuation of the drill residues (If the wax runs out, the drill can continue working. Only the total loss of the diamond indicates the end of the drill bit's life.)
DRYGRES drill bits (diameters Ø 20 to 75 mm) have a side opening that improves the cooling of the drill bit and makes it easier to remove solid waste after each drilling. Before drilling again, we must make sure that the drill bit is clean and free of any obstructions.
The maximum speed of use for DRYGRES diamond drill bits is 14000 r.p.m.
For a better finish and longer life of the drill bit, it is important to respect the proper rotational speed and make a slight orbital movement during drilling.
