Diamond drill bits from the RUBI DRYGRES PREMIUM series are designed for drilling holes in hard ceramic wall and floor tiles; they are also suitable for drilling into natural stone (e.g., granite, marble). They are designed for dry drilling using an angle grinder or a drill, with the included adapter. Thanks to vacuum welding during production and the use of high-quality materials with a high diamond density, their advantages include high drilling speed and an extra-long service life.
The core bits feature side holes designed for cooling during drilling, which helps maintain a lower temperature and extends the core bit’s lifespan. The bits with diameters of 43 mm and 68 mm have segmented diamond segments, enhancing drilling precision.
When drilling, it is necessary to apply appropriate pressure to the drill bit, as excessive pressure can cause it to overheat and thus be damaged.
Improvements in the DRYGRES PREMIUM series compared to the DRYGRES series:
Faster drilling
More than twice the service life
Improved cooling with side holes (Ø 20–85 mm)
Core bit with intermittent segments (Ø 43–85 mm)
