The RUBI DRYGRES Diamond Drill Bit (28 mm) is a high-performance tool engineered for dry drilling into hard materials such as porcelain tiles, natural stone, granite, and marble. Using advanced VACUUM BRAZED technology, diamond particles are securely bonded to the cutting rim, ensuring high resistance to friction and temperature.
The 28 mm diameter is ideal for professional installers creating holes for plumbing fixtures, water points, and electrical connections. It features an M14 thread for direct connection to angle grinders, or it can be used with a non-percussive electric drill using a specific adapter (Ref. 05976).
The bit allows for a drilling depth of 36 mm and operates at a maximum speed of 14,000 RPM. It features a lateral opening to improve air cooling and facilitate debris removal. The average lifespan is approximately 60 holes, depending on the material and usage technique.
