Drill bit for glass and ceramic GEKO HEX 5 mm

GEKO HEX 5 mm drill bit for glass and ceramic is a rotary tool accessory designed to cut clean holes in brittle materials such as glass, ceramic and glazed tiles. Its 5 mm working diameter and hardened tip are made for precision drilling with reduced risk of cracking. The HEX shank provides a secure grip in standard chucks and quick-change adapters, making it suitable for handheld drills and light-duty tasks where controlled, small-diameter holes are required.

Advantages

The drill bit combines a dedicated cutting geometry for brittle surfaces with a HEX shank that minimizes slippage in the chuck. Its narrow 5 mm diameter enables precise positioning and neat hole edges while the hardened construction increases wear resistance when used under recommended conditions. The tool is compact and easy to handle, allowing steady drilling and reliable results in tile and glass installations.

Suitable for

• Drilling holes in glass panes and mirror glass
• Creating openings in ceramic and porcelain tiles
• Installing small fixtures, hooks and fittings on glazed surfaces
• Light DIY and home repair projects requiring small-diameter holes

Key specifications

• Working diameter: 5 mm
• Shank type: HEX shank for secure grip
• Intended material: glass, ceramic, glazed tiles
• Tool type: rotary drill bit for handheld drills
• Use case: small-diameter precision drilling in brittle materials

How to use

Select a suitable handheld drill with a chuck that accepts HEX shanks, clamp the drill bit securely, and mark the drilling point on the material. Start drilling at low speed with light pressure to create a pilot depression, then increase speed slightly while maintaining steady, gentle pressure. Use cooling and lubrication where appropriate (for example, a water drip or wet sponge) to reduce heat and avoid cracking. After completing the hole, withdraw the bit slowly while the drill is still turning to minimize chipping of the edge.

Usage recommendations

Wear appropriate eye protection and gloves. Use low to moderate drill speeds and avoid excessive pressure. For fragile or tempered glass, verify suitability before drilling; for best results on tiles, drill on the glazed face with a backing support to prevent blowout.
