DRYGRES 4DRILL 8 mm diamond drill bit. Ruby

Within its range of diamond drills for dry cutting, Rubí has ​​DRYGRES 4DRILL drills. The DRYGRES 4DRILL range of diamond bits is recommended for drilling all types of ceramic tiles, especially porcelain stoneware, and other facing materials such as marble and granite. In the DRYGRES 4DRILL range of drills, Rubí has ​​used vacuum welding technology, VACUUM BRAZED, which increases resistance to temperature and friction, to fix the diamond particles to the cutting area. The DRYGRES 4DRILL bits are perfect for placing bathroom accessories or any type of decoration accessory on ceramic surfaces and / or natural stone.
DRYGRES 4DRILL diamond drill bits have been designed to be used exclusively with a corded or cordless electric drill, always WITHOUT a hammer. Their hexagonal connection allows them to quickly adapt to drills with 13mm head.
The drilling depth of the drills DRYGRES 4DRILL is 36 mm. for 6, 8 and 10 mm diameters, and 40 mm deep for 12, 14 and 20 mm diameter bits. All DRYGRES 4DRILL bits 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 to work. Only the total loss of the diamond indicates the end of the life of the bit). drill.).
Being dry cutting, it is necessary, for proper cooling of the drill, to perform a slight and constant orbital movement during drilling, as well as to remove any remaining material, between drilling and drilling.
The DRYGRES 4DRILL bits, from Rubí, have a system that blocks the loss of this wax through the back of the bit, thus concentrating the wax, always at the tip and guaranteeing lubrication during drilling.
The minimum, recommended speed of use for DRYGRES 4DRILL diamond bits is 1000 rpm For a better finish and longer duration of the drill, it is important to respect the proper turning speed and perform a slight orbital movement while drilling, as well as make sure that once the hole is finished there are no traces of the drilled material inside the drill bit.
