In its range of diamond drill bits for dry cutting, RUBI offers the DRYGRES 4DRILL drill bits. The DRYGRES 4DRILL range of diamond drill bits is recommended for drilling all types of ceramic tiles, especially porcelain stoneware and other wall materials such as marble and granite.
In designing the DRYGRES 4DRILL range of drill bits, RUBI used VACUUM BRAZED technology to attach the diamond particles to the bits, providing high resistance to temperature and friction.
The DRYGRES 4DRILL drill bits are ideal for installing bathroom accessories or any type of decorative accessory on ceramic and/or natural stone surfaces.
The DRYGRES 4DRILL diamond drill bits are designed to be used exclusively with a corded or cordless electric drill, always WITHOUT percussion. The hexagonal part allows for quick connection to drills equipped with a 13 mm chuck. The drilling depth of DRYGRES 4DRILL bits is 36 mm for diameters of 6, 8, and 10 mm and 40 mm for diameters of 12, 14, and 20 mm.
All DRYGRES 4DRILL bits contain wax inside. This wax melts during use and facilitates cooling and dust removal during drilling (if the wax runs out, the bit can continue to operate. Only complete loss of diamond indicates the end of the bit's life). Since it is used dry, it is recommended to use a gentle, constant circular motion while drilling to cool the bit. This also helps remove all residue from the drill.
RUBI's DRYGRES 4DRILL drill bits feature a system that prevents wax loss at the back of the bit, concentrating the wax at the tip and ensuring lubrication during drilling. The minimum recommended speed for DRYGRES 4DRILL diamond drill bits is 1000 rpm.
To achieve optimal results and increase the life of the drill bit, it is important to maintain the correct rotation speed and use a gentle circular motion while drilling.
