Tile drill bit DRAUMET HEX 12 mm for ceramic and porcelain tiles, hex shank

Professional diamond crown drill bit for dry and wet drilling, designed for making precise holes in ceramic and porcelain tiles, terracotta, marble, granite and natural stone. The DRAUMET HEX 12 mm tile drill bit combines a steel body with a vacuum-soldered diamond layer to deliver fast, accurate drilling with minimal chipping and extended service life.

Advantages

The vacuum-bonded diamond coating on a durable steel core provides high resistance to temperature, wear and mechanical damage, extending tool life and maintaining cutting performance. Its hex shank ensures secure grip in compatible drill chucks and quick bit changes, while the 12 mm working diameter gives consistent hole size for installations.

Suitable for

• Drilling holes in ceramic and porcelain tiles
• Cutting openings in terracotta and earthenware
• Creating holes in marble and granite
• Work on natural stone and masonry where clean edges are required

How to use

Mount the DRAUMET HEX 12 mm bit into a compatible drill or rotary tool with a hex chuck. For ceramic and porcelain tiles, start at low speed and use light pressure to establish the initial guide; increase speed moderately once the bit is stable. For harder materials such as marble or granite, use cooling water or intermittent drilling to reduce heat build-up. Keep the drill perpendicular to the surface and avoid lateral force to prevent breakage. After use, clean the bit and remove debris from the diamond crown.

Usage recommendations

Use coolant (water) when drilling hard stone and marble to extend bit life. For tiles, consider starting the hole at an angle or using a guide to prevent slipping. Replace the bit if cutting performance noticeably declines or if the diamond layer shows heavy wear.
