Drill bit GEKO 8 mm with M14 shank for ceramic and porcelain tiles

Tile drill bit GEKO 8 mm diameter with M14 shank for ceramic and porcelain tiles is a diamond crown bit designed for dry drilling. It features an M14 shank for use with angle grinders and is intended for making holes in materials such as porcelain ceramics, ceramic tiles, klinker and glazed surfaces. The inner surface is coated with wax to absorb heat from the diamond layer and reduce overheating. Outer diameter: 8 mm; diamond coating diameter: 10 mm.

Advantages

The diamond crown construction provides precise cutting and extended tool life on hard glazed and ceramic surfaces. The M14 shank ensures secure mounting in compatible angle grinders. Internal wax filling helps manage heat buildup during dry drilling, reducing the risk of diamond layer damage.

Suitable for

• Drilling holes in porcelain ceramic sanitaryware
• Creating openings in ceramic wall and floor tiles
• Punching holes through klinker and glazed surfaces
• Dry drilling applications with an angle grinder equipped with an M14 shank

How to use

Mark the drilling position on the tile and secure the workpiece. Fit the GEKO diamond crown bit into an angle grinder with an M14 mount and tighten according to the tool manufacturer's instructions. Start drilling at low speed to establish the hole, then apply steady pressure without forcing the bit. Periodically retract the bit to clear debris and allow the wax-filled interior to dissipate heat. Maintain firm control of the grinder to avoid chipping the tile.

Usage recommendations

Use personal protective equipment (safety glasses, gloves and hearing protection). For best results on large or delicate tiles, consider using a guide or pilot mark and maintaining consistent speed. Avoid excessive pressure or prolonged continuous drilling in one spot to prevent overheating; let the bit cool between passes if necessary.
