Diamond Dry Cutting Disc 4DRILL WONDER RUBI for Drilling - DRYGRES

Revolutionary Dry Drilling

The DRYGRES 4DRILL range from RUBI radically transforms water-free drilling on ceramic and natural stone. These diamond core bits adapt universally to all types of tiles, from porcelain stoneware to marble and granite. Perfect for installing sanitary and decorative accessories, they connect instantly to corded or cordless drills with a 13 mm chuck via their hexagonal shank. Strictly non-hammer use mandatory.

Vacuum Brazed Technology

The VACUUM BRAZED process ensures optimal fixation of diamond particles through vacuum brazing. This technological breakthrough offers remarkable resistance to heat and abrasion, considerably extending the tool's lifespan.

Integrated Cooling System

The incorporated wax is the key innovation of these core bits. It liquefies during operation to actively cool the tool and evacuate drilling dust. A rear retention mechanism concentrates lubrication on the cutting zone. Wax depletion does not interrupt operation: only total diamond wear marks the end of the accessory's life. To optimize longevity and precision, maintain a light, constant circular motion, and regularly remove residues between uses.
