RUBI has used the VACUUM BRAZED technology of vacuum brazing, in the DRYGRES PREMIUM range of drill bits, which increases resistance to temperature and friction, to fix the diamond particles to the cutting area.
DRYGRES PREMIUM diamond drill bits are dry cut and can be used, thanks to their M14 threaded connection, directly with a grinder or with an electric drill without a hammer, by using the drill adapter (ref. 05976).
The average life of DRYGRES PREMIUM drill bits varies according to the diameter: in those from Ø 6 to 12 mm the average life is 60 holes and in DRYGRES from Ø 20 to 85 mm the average life is 150 holes.
The average life of the drill bits ALWAYS depends on the type of material, its thickness and correct cooling and use.
The drilling depth is 30 mm
In the diameters Ø 6, 8, 10 and 12 mm, the PREMIUM DRYGRES contain wax inside. This wax melts during the use of the bit and facilitates the cooling and evacuation of the drilling debris (If the wax runs out, the bit can continue working. Only the total loss of the diamond indicates the end of the life of the bit).
The maximum speed of use for DRYGRES PREMIUM diamond drill bits is 14000 rpm
For a better finish and longer life of the bit, it is important to respect the correct turning speed and make a slight orbital movement throughout the drilling.
