The RUBI DRYGRES PREMIUM 10 mm diamond core bit is designed for drilling holes in hard ceramic tiles and is also suitable for drilling natural stone (e.g., granite, marble). It is designed for dry drilling using an angle grinder or a drill with the use of a reducer. Thanks to vacuum welding during manufacturing and the use of high-quality materials with a high diamond density, its advantages are high drilling speed and extra long service life. The core bit diameter is 10 mm.
There is a cavity in the center of the crown 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 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)
