## Summary description

RUBI 12 mm DRYGRES diamond drill bit (model 05927) designed for dry drilling. Suitable for precise boreholes in hard ceramic, gres and similar materials, this diamond-tipped bit offers consistent cutting performance for hand or drill-press use. Ideal for tile installation, plumbing and electrical passthroughs where clean, accurate holes are required.

## Long description

The RUBI 12 mm DRYGRES diamond drill bit (model 05927) is designed for dry drilling of hard ceramic materials such as gres and porcelain. It features a diamond cutting edge engineered to produce clean, precise holes with minimal chipping when used with an appropriate handheld or drill-press setup. The bit is intended for installation tasks that require accurate boreholes through tiles and similar surfaces for plumbing, electrical passthroughs and finish-work.
Advantages
The diamond tip provides consistent cutting performance and extended durability on hard ceramic surfaces. The 12 mm diameter offers a common bore size for pipe and conduit passthroughs, while the bit’s geometry reduces edge chipping and helps maintain hole roundness. Because it is optimized for dry drilling, the bit can be used without water cooling in circumstances where wet methods are impractical, simplifying on-site operation and cleanup.
Suitable for
 Drilling precise holes in gres, porcelain and hard ceramic tiles
 Creating passthroughs for plumbing pipes and fixtures
 Making openings for electrical conduits and junctions
 Tile installation and renovation where clean edges are required
Key specifications
 Cutting material: diamond tip suitable for hard ceramics
 Diameter: 12 mm
 Intended drilling method: dry drilling
 Suitable for: gres, porcelain, hard ceramic tiles
 Compatible with: handheld drills and drill presses when used with stable mounting
How to use
Mark the drilling position and secure the tile or workpiece to prevent movement. Start drilling at low speed to establish the hole and then increase rotational speed while maintaining steady, light pressure. Avoid excessive force and let the diamond edge cut the material; periodic short pauses help to reduce heat buildup. For handheld drilling, consider using a guide or jig to keep the bit perpendicular and prevent wandering. After completing the hole, clean any dust from the drilled area.
Usage recommendations
For best results, use the bit with controlled speed and minimal pressure; if prolonged drilling is required, allow short cooling pauses to extend tool life. When drilling porcelain or very dense gres, a drill guide or drill press increases accuracy and reduces the risk of breakage. Use appropriate personal protective equipment including safety glasses and a dust mask to protect from ceramic dust.
