## Summary description

GEKO HEX 4 mm drill bit designed for drilling glass and ceramic materials. Featuring a HEX shank for secure chuck grip, this bit is intended for precise hole-making in brittle surfaces such as glass, tiles and porcelain. Suitable for use with handheld drills and drill drivers for installation, repair and DIY tasks.

## Long description

The GEKO HEX 4 mm drill bit for glass and ceramics is a purpose-built cutting tool for making precise holes in brittle materials such as glass, ceramic tiles and porcelain. It features a HEX shank that improves grip in screwdriver-type chucks and quick-change hex collets, reducing slippage during low- to medium-speed drilling. The geometry of the cutting tip and the material selection are optimized to penetrate fragile surfaces while minimising cracking and chipping when used with appropriate technique.
Advantages
The HEX shank provides a secure fit in compatible drill chucks and quick-change adapters, helping to maintain concentric rotation and reduce wobble. The tip profile is designed to score and cut through glazed and non-glazed surfaces with controlled material removal, enabling accurate hole placement. The 4 mm diameter offers a common, versatile hole size for fixtures, anchors and small fittings used in installation and repair tasks.
Suitable for
Drilling holes in glass panes for hooks, wire and fittings;
Making openings in ceramic tiles and porcelain during bathroom and kitchen installations;
Light repair and DIY projects requiring small-diameter holes in brittle surfaces;
Use with handheld drills and cordless drill drivers at low to medium speeds.
When it may not be suitable
This drill bit is not intended for heavy masonry, metal, wood or concrete; attempting to use it on such materials can damage the bit and the workpiece. It is also not suitable for high-speed hammer drilling. For thick or tempered glass, specialized diamond or mosaic bits and specific procedures are recommended to avoid breakage.
Key specifications
Diameter: 4 mm
Shank type: HEX (hexagonal)
Intended materials: glass, ceramic tiles, porcelain
Compatibility: handheld drills and drill drivers with appropriate chuck or hex collet
How to use
Secure the workpiece on a stable surface and, if possible, support glass or tile from the underside. Mark the drilling point and, for glazed surfaces, score the mark with a centre punch or marker. Fit the GEKO HEX 4 mm bit into a compatible chuck or quick-change hex holder. Use low to moderate rotational speed and steady, light pressure—do not apply hammer action. For cleaner holes and reduced heat, periodically withdraw the bit to clear debris and, where appropriate, use water or coolant to keep the cutting area cool. After completing the hole, inspect edges and remove any minor burrs with fine abrasive if needed.
What to consider before purchase
Verify that a 4 mm hole meets your fastening or installation requirements;
Confirm your drill accepts a HEX shank or you have a compatible adapter;
Consider the type and thickness of the glass or ceramic—tempered glass requires special methods;
Plan for appropriate cooling and holding methods to minimise breakage.
Usage recommendations
Use low to medium drill speed, steady light pressure and cooling (water) when drilling. Support the workpiece properly and avoid hammer or impact modes to reduce risk of cracking.
