Diamond core bits from the RUBI DRYGRES PREMIUM series are designed for drilling holes in hard ceramic tiles and 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 are high drilling speed and extra-long durability.
In the center of the core bit, there is a cavity filled with wax. During drilling, the wax melts due to rising temperature, providing lubrication and cooling for the drill bit. When the wax runs out, it is recommended to replenish it—simply using a candle. When drilling, it is necessary to apply appropriate pressure to the core bit, because excessive pressure can cause it to overheat and thus be damaged.
