Diamond drill bit 6 mm RUBI model 05923 for tile, ceramic and glass drilling

Diamond drill bit 6 mm RUBI model 05923 is a specialist cutting tool designed for precise drilling in hard surfaces such as ceramic tiles, porcelain and glass. The tool has a 6 mm diameter and a diamond-cut working end that provides controlled material removal and increased wear resistance. It is intended for use with standard rotary drills and performs best with water cooling to reduce heat, extend tool life and improve hole quality during tile installation and renovation.

Advantages

The diamond-cut tip ensures accurate, clean holes with minimal chipping on fragile glazed surfaces. High-quality diamond segmentation gives longer service life compared with conventional carbide bits when working with tile, porcelain and glass. Compatibility with standard rotary drills and the ability to use water cooling provide stable cutting performance and reduced overheating. The compact 6 mm size enables precise starter holes for anchors, fixtures and fittings without unnecessary material removal.

Suitable for

• Drilling holes in ceramic wall and floor tiles
• Porcelain and glazed tile drilling for sanitary and kitchen fittings
• Making small-diameter holes in glass and mirror panels (with appropriate support)
• Installation of anchors, screws and small fixtures in tiled surfaces

Key specifications

• Diameter: 6 mm
• Tip: diamond-cut working end for hard, brittle materials
• Intended materials: ceramic tiles, porcelain, glass and similar surfaces
• Drive type: for use with standard rotary drills
• Cooling: compatible with water cooling to reduce heat and improve life

How to use

Mark the drilling point and secure the workpiece to prevent movement. Start drilling at low speed to establish a clean entry point, applying light, steady pressure. Use water cooling or a spray to keep the tip wet and remove debris; this reduces overheating and improves cutting efficiency. Maintain a vertical drilling angle and avoid excessive force which can cause cracking or premature wear. After completing the hole, withdraw the bit while the drill is still turning to clear debris and finish the edge.

Usage recommendations

For best results, use a variable-speed rotary drill set to low-to-medium RPM and continuous water supply or periodic wetting. When drilling glass, support the panel with a sacrificial backing and proceed slowly. Replace the bit when cutting performance or hole quality noticeably decreases.
