Tile drill bit GEKO 20 mm – carbide-tipped masonry bit with M14 shank

Tile drill bit GEKO M14 20 mm is a diamond-coated dry-drilling crown designed for creating clean holes in ceramic and porcelain surfaces. It features an M14 shank suitable for angle grinders and a 20 mm outer diameter with a 10 mm diamond coating, allowing efficient cutting of glazed and hard tile materials without wet cooling.

Advantages

The GEKO M14 20 mm tile drill bit provides precise hole cutting on hard surfaces thanks to its diamond coating and carbide-reinforced construction. The M14 thread ensures secure attachment to compatible angle grinders, and the dry-drilling design eliminates the need for water, simplifying use on job sites where water is impractical. Its 20 mm diameter and 10 mm cutting length are optimized for standard installation tasks in tiling and masonry work.

How to use

Install the drill bit into an angle grinder with an M14 mount and secure it according to the tool manufacturer’s instructions. Mark the drilling point on the tile, start at low speed to create a guide, then increase speed with steady, moderate pressure. Avoid excessive force and keep the tool stable to prevent chipping. Since this is a dry-drilling bit, do not apply water; allow brief pauses if the bit overheats.

Usage recommendations

Use appropriate personal protective equipment (safety goggles, gloves, dust mask) and clamp or support the tile to avoid movement. For best results on very hard or thick tiles, make short drilling intervals to prevent overheating and inspect the bit for wear regularly.
