Drill bit for glass and tiles GEKO G39710 10 x 87 mm

GEKO G39710 is a 10 x 87 mm drill bit specifically made for drilling glass and ceramic tiles. The bit features a dedicated tip geometry that enables controlled penetration of brittle, glazed surfaces while minimising the risk of cracking. It is suitable for both manual and machine drilling during installation of sanitary fittings, decorative fixtures and other mounting tasks that require precise holes in glass or tile.

Advantages

The drill bit's shaped tip and hardened cutting edges provide clean, chip-free holes in brittle materials. Its moderate overall length offers good stability and control during drilling, while the 10 mm diameter is a common size for anchors and fittings used in bathroom and kitchen installations. Designed for use in brittle, glazed surfaces, the bit reduces the need for excessive pressure and helps maintain surface integrity.

Suitable for

• Drilling holes in glass panes and glass fixtures
• Creating holes in glazed ceramic wall and floor tiles
• Installing sanitary fittings, towel rails and bathroom accessories
• Mounting decorative fixtures on tiled or glazed surfaces

Key specifications

• Material application: glass and ceramic tile
• Tip geometry: dedicated shape for brittle materials
• Diameter: 10 mm
• Overall length: 87 mm
• Compatibility: manual drilling and machine drilling (low to moderate speed)

How to use

Mark the drilling point and secure the workpiece to prevent movement. Start drilling at low speed with light pressure to allow the special tip to score the surface, then maintain steady, controlled speed without excessive force. For glazed tiles and glass, use cooling or lubrication where appropriate (for example, water) and periodically withdraw the bit to clear debris. Do not apply rapid high-pressure impacts; the bit is intended for controlled penetration in brittle materials.

Usage recommendations

Use a drill stand or guide for perpendicular holes in thin glass or large tiles, wear appropriate eye protection, and test on a scrap piece or unobtrusive area when working with decorative or valuable surfaces.
