Tile drill bit GEKO M14 10 mm for ceramic and porcelain tiles, shank M14, 10 mm diameter

Tile drill bit GEKO M14 10mm is a diamond-coated core drill designed for dry drilling in hard surfaces. It features an M14 shank compatible with angle grinders and rotary tools that accept M14 fittings. The tool is intended for creating clean holes in materials such as porcelain, ceramic tiles, clinker and glazed surfaces. The core is internally treated with wax that reduces heat transfer to the diamond layer and helps prevent overheating during use. Overall diameter: 10 mm; diamond coating length: 10 mm; shank: M14.

Advantages

The diamond coating provides efficient cutting performance on hard glazed and ceramic materials while the M14 shank ensures secure attachment to compatible angle grinders. Internal wax filling reduces heat buildup at the diamond layer, which helps maintain cutting performance and prolongs tool life under dry drilling conditions. The 10 mm diameter delivers a precise, consistent hole size for standard installations.

Suitable for

• Drilling holes in porcelain and ceramic tiles
• Creating openings in glazed tiles and clinker

How to use

Secure the GEKO M14 10mm drill bit in an angle grinder or rotary tool with an M14 fitting. Mark the drilling point on the tile or porcelain and start drilling at low speed to establish the hole. Apply gentle, steady pressure and maintain a perpendicular angle to the surface. Because the bit is intended for dry drilling, avoid excessive force and allow brief pauses if the tool or workpiece becomes noticeably hot. Use appropriate personal protective equipment such as eye protection, gloves and a dust mask.

Usage recommendations

For best results on large or thick tiles, begin with a small pilot impression or use a guide to prevent slipping. Monitor the bit temperature during extended use; if overheating occurs, allow cooling periods. Use with compatible M14 angle grinders and follow the tool manufacturer's safety instructions.
