Rubi - Set of 5 Brocas Drygres Rosca 5/8"

DRYGRES kits are the most economical solution for users who need to perform dry drilling of different diameters in any type of ceramic tile. The DRYGRES range of diamond drill bits is recommended for drilling all types of ceramic tiles, especially porcelain stoneware, and other covering materials such as marble and granite. In its DRYGRES range of drill bits, RUBI has used VACUUM BRAZED technology, which increases resistance to temperature and friction, to attach the diamond particles to the cutting area. RUBI offers kits with several configurations, always designed to offer professionals the option that best suits their needs. DRYGRES kits have been designed primarily so that ceramic tile installers can achieve the best results when drilling holes for water inlets, drains, light points, etc. The DRYGRES kits include: - MULTIDRILL guide - 28, 35, 43, and 68 mm diamond core bits (ref. 50917) - 28, 35, 43, 50, and 68 mm diamond core bits (ref. 50936) - 6, 8, 20, 35, 50, and 68 mm diamond core bits (ref. 50996) - 6 (x2), 20, and 35 mm diamond core bits and TCR-115 SUPERPRO diamond blade (ref. 68923) - Carrying case DRYGRES diamond core bits are designed for dry cutting and, thanks to their M14 screw connection, can be used directly with a grinder or non-percussion electric drill, using the adapter for drill (ref. 05976). The average life of DRYGRES drill bits from 20 to 75 mm is 60 holes. The average life of drill bits ALWAYS depends on the type of material, its thickness, as well as its proper cooling and use. The drilling depth of DRYGRES drill bits is 36 mm. DRYGRES drill bits (diameters 20 to 75 mm) have a side opening that improves bit cooling and facilitates the removal of solid residue after each drilling. Before drilling again, ensure that the drill bit is clean and free of any obstructions. The maximum operating speed of DRYGRES diamond drill bits is 14,000 rpm. To achieve a better finish and longer bit life, it is important to maintain the correct rpm speed and use a slight orbital motion while drilling.
