Drill bit for glass and ceramics GEKO 10 mm HEX shank

Diamond-tipped drill bit GEKO 10 mm with a HEX shank is designed for drilling brittle materials such as glass and ceramics. The 10 mm diameter and diamond cutting tip provide controlled material removal and reduced risk of cracking when used with appropriate speed and light pressure. The hexagonal shank ensures a secure grip in chucks and quick-change holders, improving stability during drilling.

Advantages

The diamond tip allows accurate and clean holes in glazed tiles, glass panes and porcelain without chipping when operated correctly. The HEX shank minimizes slippage in the drill chuck and supports higher torque transfer for steady rotation. The bit’s geometry is optimized for low to moderate drilling speeds and for use with coolant or water to extend tool life and reduce heat build-up.

Suitable for

• Drilling holes in glass panes and mirrors
• Creating openings in glazed ceramic tiles
• Working with porcelain sanitary ware and similar brittle materials
• Light DIY, glazing and tiling tasks requiring precise holes

Key specifications

• Tip: diamond-tipped cutting edge for brittle materials
• Diameter: 10 mm
• Shank type: hexagonal (HEX) for secure chuck grip
• Recommended speed: low to moderate RPM for controlled cutting
• Cooling: compatible with water or coolant application to reduce heat

How to use

Secure the GEKO 10 mm diamond bit in a compatible drill or rotary tool with a chuck that accepts a hex shank. Mark the drilling point on the material and start at a low speed to establish a steady contact point; light pressure should be applied to avoid cracking the workpiece. For best results, use a backing support under the workpiece when possible and add water or coolant to the drill area to keep the tip cool and to remove debris. Increase speed only if the bit runs smoothly and material removal is consistent.

Usage recommendations

Use protective eyewear and gloves, clamp or support the workpiece securely, and maintain steady low to moderate speed with light pressure. Do not force the drill; pause periodically to add water and prevent overheating. The bit is intended for brittle materials—avoid using it on hard metals or timber to prevent damage.
