Tile drill bit GEKO 7159992 M14 shank, 30 mm diameter for ceramic and porcelain tiles

Tile drill bit GEKO M14 30 mm for ceramic and porcelain tiles, shank M14, 30mm diameter is a diamond crown drill bit designed for dry drilling. It has an M14 shank compatible with angle grinders and is intended for making holes in materials such as porcelain ceramic products, ceramic tiles, clinker and glazed surfaces. The outer diameter is 30 mm and the diamond coating depth is 10 mm.

Advantages

The diamond crown provides efficient material removal and extended cutting life when used for dry drilling on hard tile surfaces. The M14 shank ensures secure mounting in angle grinders and similar tools. A 30 mm outer diameter with a 10 mm diamond layer offers a balance between hole size and wear resistance for tile applications.

Suitable for

• Drilling holes in porcelain ceramic products
• Drilling through ceramic wall and floor tiles
• Creating openings in clinker and glazed tiles
• Use with angle grinders fitted with M14 shank

How to use

Mark the drilling location on the tile and secure the workpiece to prevent movement. Fit the GEKO M14 diamond crown onto an appropriate angle grinder with an M14 holder. Start drilling at low speed to create a shallow guide groove, then increase speed and apply steady, moderate pressure. Keep the tool perpendicular to the surface and avoid excessive side forces. As this drill bit is intended for dry drilling, do not use continuous water cooling; follow the tool and accessory manufacturer recommendations for intermittent cooling if required.

Usage recommendations

Use personal protective equipment (safety glasses, gloves, dust mask) and clamp tiles securely. For best hole quality and longer tool life, drill slowly, allow the bit to cool between passes, and replace the bit when diamond wear reduces cutting performance.
