RUBI DRYGRES PREMIUM Diamond Drill Bits

The RUBI DRYGRES PREMIUM range is designed for precise and efficient drilling of all types of ceramic tiles, including porcelain stoneware, as well as marble and granite.

• 6–12mm bits: Ideal for fixing bathroom and decorative accessories onto tiled surfaces.

• 20–85mm bits: Specially designed for tile fixers to achieve perfect results when drilling for sockets, pipes, drains, lighting, and fittings.

Connection & Compatibility:

• M14 threaded connection for direct use with angle grinders.

• Can also be used with an electric drill (non-hammer) when combined with the drill adapter.

Drilling Depth:

• 30mm (for bits 6–35mm)

• 38mm (for bits 43–85mm)

Cooling System & Performance:

• 6, 8, 10 & 12mm sizes contain a wax core that melts during use, aiding cooling and debris removal.

  • If the wax runs out, drilling can continue.

  • The bit’s lifespan only ends once the diamond layer is fully worn.

• 20–85mm sizes feature a lateral opening for improved cooling and easier debris removal.

• 43mm+ sizes include a segmented design to increase stability during drilling.

Tips for Best Results:

• Always respect the correct RPM.

• Use a slight orbital motion throughout drilling.

• Clear debris between holes for longer bit life and a cleaner finish.
