Drill bit set for glass and ceramic GEKO 7 pcs HEX

GEKO 7-piece drill bit set for glass and ceramic materials. This set contains seven HEX-shank bits specifically shaped and tempered for controlled cutting of glass and ceramic tiles. The HEX shank provides anti-slip seating in compatible chucks, improving torque transfer and stability during drilling. The bits are intended for household repairs, tile installation and light professional tasks where precise, chip-minimizing holes are required.

Advantages

The set offers a compact selection of diameters suitable for common fixture and fitting holes. HEX-shank design reduces slippage and simplifies bit changes in drills with compatible chucks. The cutting geometry is optimized to reduce chipping on brittle surfaces, helping to achieve clean holes in glass and glazed ceramic tiles. The assortment is lightweight and convenient to store, making it practical for portable tool kits.

Suitable for

• Drilling holes in glass panes and mirrors
• Creating openings in ceramic wall and floor tiles
• Installing bathroom and kitchen fittings that require clean holes
• Home repair and light professional tiling work

Key specifications

• Set composition: 7 drill bits with HEX shanks
• Intended materials: glass and ceramic (glazed tiles, mirrors)
• Shank type: HEX for reduced slippage in compatible chucks
• Cutting geometry: tip and flute shape designed to minimize chipping on brittle surfaces
• Typical use: low-speed, controlled drilling to prevent cracking

How to use

Secure the appropriate HEX-shank bit in a drill with a compatible chuck. Mark the drilling point on the glass or tile and, if possible, use adhesive tape over the mark to reduce surface sliding. Start at low speed and apply gentle, steady pressure; avoid high speeds that generate heat or cause cracking. For glass, consider using a coolant such as water to reduce heat buildup. Once the hole is initiated, maintain control and steady feed until the bit penetrates the material. After drilling, clean the hole edges to remove any fine debris.

Usage recommendations

Use low to moderate drill speeds and intermittent drilling with coolant (water) when working with glass or glazed ceramic to minimize heat and chipping. Always wear appropriate eye protection and handle drilled pieces carefully to avoid sharp edges.
