The RUBI DRYGRES Diamond Drill Bit (20 mm) is a premium tool designed for dry drilling into porcelain tiles, ceramics, natural stone, granite, and marble. Utilizing VACUUM BRAZED technology, the diamond particles are securely fixed to the cutting area, significantly increasing resistance to high temperatures and friction during operation.
This 20 mm bit is specifically engineered for creating precise holes for water points, drainage, and electrical connections. It features an M14 thread for direct connection to grinders, or it can be used with a non-percussive electric drill using an adapter (Ref. 05976). The bit includes a lateral opening that improves cooling and facilitates the removal of solid debris after each drilling.
With a drilling depth of 36 mm and a maximum operating speed of 14,000 RPM, it offers an average life span of approximately 60 holes (depending on material usage).
