Diamond drill bit for tiles Abraboro 12 mm AB51512000

Abraboro diamond drill bit for tiles, 12 mm diameter, model AB51512000, is engineered for precise drilling in ceramic, porcelain and glazed tiles. The bit features a diamond-segment tip that provides clean hole edges and consistent performance when used at low to moderate speeds. It is compatible with hand drills and drill stands and is intended for wet drilling to reduce heat and extend the life of the diamond segments. This tool is suitable for installation and repair work in bathrooms, kitchens and other tiled surfaces.

Advantages

The diamond cutting edge produces accurate, chip-free holes in hard tile surfaces. A 12 mm diameter offers a common size for pipe and fixture penetrations. Designed for wet drilling, the bit achieves longer service life and more reliable cutting when cooled with water. Construction and balance of the bit reduce vibration and help maintain straight drilling, allowing for repeatable results in renovation and installation tasks.

Suitable for

• Drilling holes for plumbing pipes and fittings in ceramic and porcelain tiles
• Creating openings for electrical boxes and conduit in tiled walls
• Tile work during bathroom and kitchen renovation or repair
• Use with a drill stand for precise, perpendicular holes

Key specifications

• Tip type: diamond-segment cutting edge suitable for hard glazed surfaces
• Diameter: 12 mm usable cutting diameter
• Compatible materials: ceramic tile, porcelain tile, glazed tile
• Recommended operation: wet drilling with continuous water cooling
• Suitable tools: hand drill or drill stand at low to moderate speed

How to use

Secure the tile and mark the drilling point. If possible, mount the drill bit in a drill stand for improved perpendicular alignment. Begin drilling at low speed to establish the contact point, then maintain low to moderate RPM while applying gentle, steady pressure. Keep the cutting area continuously cooled with water to reduce heat buildup and to remove debris; intermittent pauses may be used if wet cooling is limited. After the hole is complete, clean the bit and the workpiece to remove slurry and particles.

Usage recommendations

Use consistent wet cooling and avoid excessive speed or pressure to maximize diamond segment life. For best results on large or delicate tiles, use a drill stand or guide and take time to align the bit before drilling.
