5/16” DRYGRES Cutting Drill Bits 05932
The range of DRYGRES diamond drills are recommended for the drilling of all types of ceramic tile, especially porcelain stoneware, and other coating materials such as marble and granite.
In the range of DRYGRES drills, RUBI has used the vacuum welding technology VACUUM BRAZED, which increases the resistance to temperature and friction, to fix the diamond particles to the cutting area.
DRYGRES drill bits, diameters Ø 6 to 12 mm., Are perfect for the placement of bathroom accessories or any type of decoration accessory on ceramic surfaces. The rest of the diameters of the range of DRYGRES diamond drills, from Ø 20 to 75 mm., Have been designed, thinking mainly, so that the ceramic tile setter can obtain the best results when making the necessary perforations for shots of water, drains, points of light, etc.
DRYGRES diamond drills are dry cutting and can be used, thanks to its connection with M14 thread, directly with a grinder or electric drill without hammer, by using the drill adapter (ref 05976).
The average life of DRYGRES drills varies according to diameter. In the Ø 6 to 12 mm the average life is 25 holes and in the DRYGRES Ø 20 to 75 mm the average life is 60 holes.
The average life of the drills depends, ALWAYS, on the type of material, its thickness and the correct cooling and use.
The drilling depth of DRYGRES drills is 36 mm.
In diameters Ø 6, 8, 10 and 12 mm, the DRYGRES contain wax inside. This wax melts during the use of the bit and facilitates the cooling and evacuation of the remains of the drilling (If the wax exhausts, the drill can continue working.) Only the total loss of the diamond indicates the end of the life of the drill).
DRYGRES drills (diameters Ø 20 to 75 mm) have a lateral opening that improves the cooling of the bit and facilitates the elimination of solid waste after each drilling. Before making a new perforation, we must make sure that the bit is clean and free of any obstruction.
The maximum speed of use for DRYGRES diamond drills is between 14000 r.p.m.
For a better finish and longer life of the bit, it is important to respect the proper turning speed and perform a slight orbital movement while drilling.
