Diamond drill bit Abraboro 16 mm for tiles, model AB51516000

The Abraboro diamond drill bit 16 mm (model AB51516000) is designed for precise drilling in tiles and ceramic materials. With a 16 mm cutting diameter and a diamond cutting edge, this bit creates clean, accurate holes in hard glazed surfaces and ceramic tiles. It is suitable for use with standard drill rigs and supports wet drilling to manage heat and prolong cutting life.

Advantages

The diamond cutting edge provides consistent performance on hard, glazed surfaces, delivering accurate hole shapes and reduced chipping. The 16 mm diameter offers a balance between speed and control for common tile fittings. Compatibility with wet drilling reduces friction and heat buildup, which helps extend the service life of the bit and maintains cutting efficiency over repeated use.

Suitable for

• Drilling holes for plumbing fixtures through ceramic and porcelain tiles
• Installing electrical boxes or conduit through tiled walls
• Creating openings for anchors or mounting hardware in bathroom or kitchen tiles
• Precision drilling in glazed ceramic, porcelain and similar hard tile materials

Key specifications

• Cutting diameter: 16 mm
• Cutting material: diamond edge
• Intended materials: glazed ceramic, porcelain and similar tile materials
• Recommended drilling method: wet drilling to reduce heat
• Compatible with: standard drill rigs and hammerless rotary drilling systems (low speed, steady feed)

How to use

Secure the tile or ensure the workpiece is fixed to prevent movement. Mark the drilling point and start at low speed to establish a pilot seat; apply steady, moderate pressure without forcing the bit. Use a water feed or occasional cooling to keep the cutting edge wet and to flush debris from the hole. Maintain a slow to medium drill speed suitable for diamond bits to avoid overheating and ensure a clean cut. After drilling, withdraw the bit while the hole is still wet to clear remaining slurry.

Usage recommendations

Use cold water or a continuous water feed for wet drilling to reduce heat and extend bit life. Avoid excessive axial force and high speed; allow the diamond edge to cut at a steady rate. For brittle or thin tiles, consider backing the workpiece or using a sacrificial support to prevent cracking.
