Diamond core drill bit GEKO G65014 — 14 mm for tiles

Diamond core drill bit GEKO G65014 — 14 mm for tiles is a straight-shank diamond-tipped core bit designed for drilling precise holes in ceramic and porcelain tiles. The 14 mm cutting diameter is intended for creating clean openings for fixtures, pipes and fasteners when installing tiles in bathrooms, kitchens and other tiled surfaces. Use with a drill or rotary tool that supports core bits and observe recommended feed, cooling and backing to reduce chipping and extend bit life.

Advantages

This 14 mm diamond core drill bit provides accurate round holes with minimal chipping when used with moderate feed and water cooling. The diamond segment cutting edge offers improved durability compared with conventional carbide bits for hard glazed surfaces. Its straight shank fits common keyed and keyless chucks, enabling use with hand drills or drill rigs designed for tile work. The compact diameter is convenient for installations requiring small-diameter penetrations.

Suitable for

• Drilling holes for plumbing pipes and fittings through ceramic and porcelain tiles
• Creating openings for anchors, screws and small fixtures in tiled walls
• Tile installations in bathrooms, kitchens and utility areas where precise small holes are needed

Key specifications

• Cutting diameter: 14 mm
• Cutting material: diamond segments
• Shank type: straight shank compatible with standard chucks
• Intended materials: glazed ceramic tiles, porcelain tiles
• Drilling method: wet or controlled dry with proper backing to reduce chipping

How to use

Mark the drilling position and support the tile from the rear or use masking tape on the surface to reduce glazing damage. Start drilling at low speed to establish the hole and apply light, steady pressure. For best results use continuous water cooling or periodic wetting to keep the diamond segments cool and flush away debris. If using a handheld drill, maintain a stable grip and keep the drill perpendicular to the tile. If drilling through finished walls, ensure any substrate behind the tile is also suitable for the chosen drill method.

Usage recommendations

To maximize service life and hole quality, use water cooling whenever possible, avoid excessive feed pressure, and back the tile to prevent blowout. Replace the bit once cutting becomes slow or produces excessive chipping. Use appropriate protective equipment, eye protection and dust control when drilling.
