By choosing this offer, you can be sure that you are purchasing a 100% ORIGINAL product from an Authorised Distributor of the RUBI brand in Poland. RUBI CORE DRILL BIT FOR PREMIUM PORCELAIN TILES 65mm DRY. The DRYGRES PREMIUM diamond drill bits range is ideal for drilling in all types of tiles, particularly in porcelain stoneware, as well as other coverings such as marble or granite. The diamond in the DRYGRES PREMIUM drill bits is applied using vacuum soldering technology, which increases their resistance to high temperatures and friction. The DRYGRES PREMIUM drill bits with a diameter of 6-12 mm are perfect for installing bathroom accessories and decorative elements. The other DRYGRES PREMIUM cores with diameters of 20-85 mm allow for professional preparation of holes for water installations, drains, electrical boxes, etc. The DRYGRES PREMIUM drill bits, thanks to the M14 thread, can be used directly on a grinder or, with the connector (ref. 05976), on a non-hammer drill. The average durability of the DRYGRES PREMIUM drill bits with a diameter of 6-12 mm is 60 holes, and for sizes 20-85 mm - 150 holes. The durability of the drill bits ALWAYS depends on the type of material and its thickness, as well as proper cooling and usage. The drilling depth of DRYGRES PREMIUM is 30 mm for diameters of 6-35 mm, and 38 mm for diameters of 43-85 mm. The DRYGRES PREMIUM drill bits with a diameter of 6-12 mm contain wax inside, which melts during use, facilitating cooling and the removal of drilled material particles (the bits can still be used even after the wax has been exhausted; the lifespan of the bit is indicated only by the complete loss of diamonds). The side hole in the DRYGRES PREMIUM cores with diameters of 20-85 mm allows for better cooling and the removal of debris after each hole is drilled. It is important to clean and check the drill bit before starting to drill the next hole. The drill bits with diameters of 43-85 mm are segmented for better stability during drilling. The maximum working speed of the DRYGRES PREMIUM drill bits is from 14,000 rpm. To ensure a good finish of the hole and the durability of the drill bit, the specified rotational speeds should not be exceeded; it is also recommended to make circular movements with the drill bit for better cooling.
