Tile drill bit Proline 8 mm (1/4") – for ceramic and mosaic tiles

Proline tile drill bit with vacuum-brazed industrial diamonds, 8 mm diameter and 1/4" HEX shank, designed for drilling clean holes in ceramic and mosaic tiles. The bit is intended for forming holes in stone and ceramic tiles and fits standard drill drivers with a 1/4" HEX holder. Use dry drilling as recommended for this tool; apply steady, gentle pressure and low rotational speed to avoid chipping fragile tile surfaces.

Advantages

The vacuum-brazed diamond tip ensures durable cutting performance and consistent hole quality in brittle materials. The 1/4" HEX shank provides secure attachment to drill drivers and quick bit changes. The compact 8 mm diameter produces accurate holes suitable for anchors and screws commonly used in tile installations.

Suitable for

• Drilling 8 mm holes in ceramic wall and floor tiles
• Creating holes in mosaic and natural stone tiles
• Preparing mounting points for anchors, screws and small fittings

How to use

Secure the bit in a drill driver with a 1/4" HEX holder. Position the bit perpendicular to the tile surface and start drilling at low speed with light, steady pressure. Maintain control to prevent the bit from walking on the tile surface. Follow the dry-drilling recommendation for this bit—do not flood with water. If needed, pause periodically to avoid overheating.

Usage recommendations

Use low rotational speed, minimal pressure and correct alignment when working on ceramic or mosaic tiles. For fragile or very thin tiles, consider supporting the tile from behind or using a backing material. Verify compatibility with anchors and screws before final installation.
