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.
There is a cavity in the center of the drill bit that is filled with wax. During drilling, the wax begins to melt due to the rising temperature, thereby lubricating and cooling the drill bit. When the wax runs out, it is recommended to refill it—simply using a candle. When drilling, it is necessary to apply appropriate pressure to the core 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)
