DRYGRES PREMIUM diamond cutters are perfect for drilling all types of ceramic tiles, in particular porcelain stoneware, and other covering materials such as marble and granite.
The DRYGRES PREMIUM diamond cutters are for dry cutting and can be used, thanks to their M14 threaded connection, directly with a grinder or with an electric drill without percussion, using the drill adapter.
The average life of DRYGRES PREMIUM drills varies based on the diameter: in those from Ø 6 to 12 mm the average life is 60 holes and in DRYGRES from Ø 20 to 85 mm the average life is 150 holes. This ALWAYS depends on the type of material, its thickness and correct cooling and use.
The drilling depth of the DRYGRES PREMIUM drills is 30 mm for bits from Ø 6 to 35 mm and 38 mm for bits from Ø 43 to 85 mm.
The maximum use speed of the DRYGRES PREMIUM diamond cutters is 14000 rpm
For a better finish and longer life of the cutter, it is important to respect the correct rotation speed and make a slight orbital movement when drilling.
