Rubi has expanded its Drygres Premium range of diamond drill bits designed for drilling all types of ceramic tiles, especially porcelain stoneware and other covering materials such as marble and granite.  

Vacuum brazing technology was used in the Drygres Premium range of drill bits, to afix the diamond particles to the cutting area, increasing resistance to temperature and friction. The 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). 

Drygres Premium drill bits, with diameters of 1/4" to 1/2" (6 to 12 mm), are perfect for laying bathroom accessories or any type of decoration accessory on ceramic surfaces. The rest of the diameters range from 3/4" to 3 5/16" (20 to 85 mm) and have been designed mainly so that the ceramic tile fixer can obtain the best results when making the necessary drilling for sockets.
