RUBI has used vacuum brazed diamond welding technology in the DRYGRES Premium range of drill bits, which increases resistance to temperature and friction, to fix the diamond particles to the cutting area.
The RUBI DRYGRES Premium M14 Diamond Drill Bits with diameters 6, 7, 8 10 and 12 mm are perfect for drilling holes for placing bathroom accessories or any type of decoration accessory on ceramic surfaces. The rest of the available diameter sizes of RUBI DRYGRES Premium M14 Diamond Drill Bits from Ø 20 to 85mm, are perfect for cutting the necessary holes for taps, water drains, light points, etc.
The RUBI DRYGRES Premium M14 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 a RUBI M14 drill adapter.
The average life of a RUBI DRYGRES Premium M14 Diamond Drill Bit varies depending on the diameter: Ø6 to 12mm ones have an average life of 60 holes and diameters from Ø20 to 85mm the average life is 150 holes. The average life of drill bits always depends on the type of material, its thickness and correct cooling and use. Poor drilling technique or care of the bit with result in a shortened service life.
The drilling depth of RUBI DRYGRES Premium M14 Diamond Drill Bits is 30 mm for diameters from Ø6 to 35mm and 38mm for diameters from Ø43 to 85mm.
For diameters Ø6, 8, 10 and 12mm, each drill bit contains a wax core that melts during use and facilitates cooling and evacuation of drilling debris. (If the wax runs out, the drill bit can continue working. Only the total loss of the diamond indicates the end of the life of the drill bit)
The RUBI DRYGRES Premium M14 Diamond Drill Bits with diameters from Ø20 to 85mm 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 a new hole, we must ensure that the drill bit is clean and free of any obstruction. Drill bit diameters from Ø43 mm upwards have segmented diamond cutting edges to improve stability during drilling.
The maximum speed of use for these 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 appropriate rotation speed and perform a slight orbital movement throughout the drilling process.
