Diamond core drill Bosch Dia-Bohrer EXPERT for ceramics 8 mm, wet drilling, MPN 2608599050

The Bosch Dia‑Bohrer EXPERT for ceramics 8 mm is a diamond core drill bit designed for wet drilling in ceramic materials. It produces clean, precise holes in tiles, porcelain and similar hard ceramic surfaces by using a diamond‑impregnated cutting edge and water cooling to control temperature and reduce dust. The bit is suitable for use with portable drills or drill presses when an appropriate adapter and proper mounting are used.

Advantages

This 8 mm diamond core drill offers accurate holemaking with minimal chipping on glazed surfaces thanks to its precision ground cutting rim. Wet drilling with water reduces friction and heat build‑up, which extends tool life and maintains cutting performance. The robust diamond bond is optimized for ceramic substrates, providing consistent cutting speed and durability under moderate drilling conditions.

Suitable for

• Drilling clean holes in ceramic wall and floor tiles
• Creating openings for plumbing fixtures and pipe work
• Installing electrical conduit and wall boxes in tiled surfaces
• Precision work on porcelain sanitary ware and ceramic panels

Key specifications

• Drill type: diamond core drill for wet drilling
• Intended material: ceramic, porcelain and similar hard tiles
• Cutting diameter: 8 mm
• Cooling method: wet (water) cooling recommended
• Compatible tool: handheld drills and drill presses with suitable chuck or adapter

How to use

Secure the workpiece and mark the drilling position. Fit the diamond core drill into the drill chuck or adapter and ensure it is tightened correctly. Start with a low drill speed and apply gentle, steady pressure; introduce a constant flow of water to the drilling area to keep the bit cool and to clear debris. For best results, allow the tool to do the cutting rather than forcing it; periodically withdraw the bit to remove slurry when drilling deeper holes.

Recommendations

Use personal protective equipment such as safety glasses and gloves, and ensure adequate water supply for continuous cooling. Avoid dry drilling on ceramic surfaces to prevent overheating and premature wear of the diamond bond. For handheld drilling on large tiles, consider using a guide or template to maintain perpendicular entry and reduce the risk of slipping.
