RUBI DRYGRES 4DRILL Diamond Drill Bits

The RUBI DRYGRES 4DRILL range is specially designed for drilling all types of ceramic tile, including porcelain stoneware, as well as marble and granite.

Manufactured with advanced VACUUM BRAZED technology, the diamond particles are firmly fixed to the cutting edge, ensuring higher resistance to heat and friction for a longer working life.

Perfect for:

  • Installing bathroom accessories

  • Fitting decorative accessories on ceramic or natural stone surfaces

Key Features:

  • Dry cut only – no water required

  • Hexagonal connection for quick fitting to standard drills with a 13mm chuck

  • Compatible with cordless & electric drills (min. 1000 RPM recommended)

  • Self-lubricating wax core – melts during drilling to aid cooling and debris removal

  • Wax retention system ensures lubrication remains focused at the tip

  • For longer life: use a slight orbital movement while drilling and clear debris between holes

⚠️ Note: Once the diamond layer is fully worn, the drill bit has reached the end of its service life.
