The RUBI DRYGRES Diamond Drill Bit (8 mm) is a professional tool designed for dry drilling into hard materials such as porcelain tiles, ceramics, granite, and marble. Manufactured with VACUUM BRAZED technology, this bit ensures high resistance to friction and temperature, making it ideal for installing bathroom accessories and wall plugs.
This 8 mm diameter bit features an internal core of special wax. This wax melts during use to provide lubrication and facilitate cooling, eliminating the need for water.
It comes with an M14 thread for direct connection to angle grinders (max speed 14,000 RPM) or can be adapted for electric drills (non-percussive) using a specific adapter (Ref. 05976). The average life span is approximately 25 holes, depending on the material and usage technique.
