Diamond drill bit for tiles RUBI 01959 — wet drilling, Ø (unspecified) precision core bit

RUBI 01959 is a diamond core drill bit engineered for wet drilling of ceramic, porcelain and natural stone tiles. Designed to deliver precise holes with minimal chipping, this core bit requires a continuous water supply to cool the cutting edge and evacuate slurry. It is intended for tile installers, renovation professionals and DIY users who need accurate circular openings for pipes, fittings and fastenings when working on tiled surfaces.

Advantages

The diamond cutting edge ensures consistent cutting performance and extended life when used under wet conditions. Wet drilling reduces heat and dust, improving hole accuracy and preserving tile integrity. The core bit produces clean, low-chipping cores and smooth hole walls, which reduces the need for post-drilling finishing. Compatibility with standard drill rigs, angle drills and adapters makes the bit versatile for onsite and workshop use.

Suitable for

• Drilling holes for plumbing pipes and conduits in ceramic and porcelain tiles
• Creating openings for electrical fittings and fixtures in tiled walls
• Making clean passages for anchors, screws and anchors in renovation projects
• Professional tile installation and repair where precise circular holes are required

Key specifications

• Application: wet drilling of ceramic, porcelain and natural stone tiles
• Cutting material: diamond cutting edge for durability and precision
• Cooling method: water-cooled operation to reduce heat and remove debris
• Compatibility: suitable for drill rigs, angle drills and standard adapters
• Result: low-chipping cores and smooth hole walls for minimal finishing

How to use

Secure the tile or workpiece to prevent movement, and set up a continuous water feed to the cutting area before starting. Fit the core bit to a compatible drill or drill rig using the appropriate adapter and set the drill to a moderate rotational speed suitable for diamond core bits. Apply steady, even pressure without forcing the bit; allow the diamond edge to cut the material while water cools and flushes debris. After completing the hole, stop the drill and rinse the core and hole to remove slurry.

Usage recommendations

Use personal protective equipment, including eye protection and gloves. Maintain a constant water flow during drilling to maximize bit life and hole quality. For best results on large-diameter holes or thick tiles, use a drill rig with a stable guide to ensure perpendicular drilling and consistent pressure.
