The Rubi DRYGRES PREMIUM diamond drill bits are designed for cutting ceramic tiles, porcelain stoneware, marble, and granite. They provide high precision and durability for professional use.
These drill bits use VACUUM BRAZED technology, which enhances resistance to heat and friction. This ensures a longer lifespan and consistent performance.
Smaller sizes (Ø 6-12 mm) are ideal for installing bathroom accessories and decorative fixtures. Larger sizes (Ø 20-85 mm) are perfect for creating holes for taps, drains, and lighting installations.
DRYGRES PREMIUM drill bits are designed for dry cutting. They feature an M14 thread, making them compatible with grinders. With an adapter, they can also be used with a hammerless drill.
The lifespan of the drill bits varies by size. The Ø 6-12 mm range lasts approximately 60 holes, while the Ø 20-85 mm range can drill up to 150 holes. However, actual longevity depends on material type, thickness, cooling, and proper use.
Drilling depth also varies. Ø 6-35 mm drill up to 30 mm, while Ø 43-85 mm reach 38 mm. The Ø 6, 8, 10, and 12 mm bits contain internal wax that melts during use, aiding cooling and debris removal. If the wax is depleted, the bit can still function until the diamond coating wears out.
Larger drill bits (Ø 20-85 mm) include a side opening for improved cooling and easy waste removal. Bits Ø 43 mm and above have a segmented edge to enhance stability during drilling.
The maximum operating speed for DRYGRES PREMIUM drill bits is 14,000 RPM. For the best results, maintain the recommended speed and use a slight orbital movement while drilling.
