Diamond drill bit for gres Smart 27 mm (brand: Smart, MPN 25-270)

Diamond drill bit 27 mm for gres by Smart is designed to create precise round holes in dense ceramic materials and porcelain stoneware. The bit features a diamond-impregnated cutting edge that improves cutting efficiency and extends tool life when used with water cooling. It is compatible with standard electric drills and drill rigs and intended for applications where clean, accurate holes are required in hard glazed surfaces.

Advantages

The diamond-impregnated cutting edge delivers consistent cutting performance and reduced chipping on glazed ceramics. A robust cylindrical body ensures stable drilling and straightforward centering in pilot marks. When used with proper water cooling, the bit operates at lower temperatures, which helps preserve both the tool and the material surface. The 27 mm diameter provides a commonly needed size for plumbing fixtures and tile penetrations while maintaining a compact profile for easier handling.

Suitable for (tasks / use cases)

• Drilling holes for bathroom fixtures through porcelain stoneware and glazed tiles
• Tile installation and penetrations for plumbing and ventilation
• Creating passages for pipes, cables, and mounting anchors in hard ceramic surfaces

Key specifications

• Cutting edge: diamond-impregnated segment for hard ceramics
• Diameter: 27 mm
• Intended material: gres (dense ceramic) and porcelain stoneware
• Cooling: recommended water cooling to reduce heat and extend life
• Drive compatibility: suitable for electric drills and drill rigs with appropriate chuck

How to use

Mark the drilling position and, if possible, use a center punch or guide to prevent slipping. Begin drilling at low speed, applying light, steady pressure; keep the drill perpendicular to the work surface. Use continuous or periodic water cooling to reduce heat and wash away dust and debris. Increase speed gradually only after the cutting edge has established a stable groove. After completing the hole, stop the drill and allow the bit to cool before handling or storing.

Usage recommendations

For best results, use an appropriate drill rig or a steady hand with a drill fitted to the correct chuck size, maintain constant water cooling, and avoid excessive lateral pressure. Wear eye protection and follow standard safety practices when drilling hard ceramic tiles.
