Diamond Core Drill Bit Drygres Rubi Ø 43 mm - Dry Drilling Porcelain and Ceramic Tile

Fixation Technology

RUBI DRYGRES core drill bits utilize VACUUM BRAZED technology, a vacuum welding process that locks diamond grains with superior adhesion. This process ensures increased heat resistance and remarkable stability during abrasive cutting.

Application Range

Compact sizes from 6 to 12 mm facilitate the installation of sanitary and decorative fixtures on tiles. The 20 to 75 mm diameters in the EASYGRES range meet the demands of technical construction sites: drilling water supply lines, drainages, and electrical provisions.

Machine Compatibility

These diamond tools operate exclusively dry. The M14 interface allows direct mounting on angle grinders or non-impact drills. For use with standard electric drills, the adapter reference 05976 is essential.

Technical Specifications

Cooling Systems

Models 6, 8, 10 and 12 mm feature an internal thermofusible wax that liquefies upon friction contact to lubricate and evacuate debris. The tool retains its effectiveness after the wax dissipates; only complete diamond erosion determines replacement. Diameters 20 to 75 mm feature a side window promoting ventilation and residue cleaning. Systematic cleanliness checks are required before each restart.

Usage Tip

To preserve finish quality and maximize longevity, maintain appropriate rotation speed while applying a slight orbital movement during the drilling operation.
