Diamond glazing drill bit GEKO G00445-D 9.0 mm – pack 50 pcs

The Diamond glazing drill bit GEKO G00445-D 9.0 mm is a specialist rotary tool designed for creating precise holes in glazed tiles, ceramics and other hard glazed surfaces. Supplied in a pack of 50 pieces, each bit features a diamond-coated cutting tip that improves cutting performance and wear resistance compared with conventional carbide tips. The bit is intended for use with handheld or bench drills at appropriate speeds and with cooldown measures to maintain tip life and hole quality.

Advantages

The diamond tip delivers accurate, clean holes with reduced chipping on glazed surfaces and extended durability during repetitive drilling. The consistent 9.0 mm diameter across the pack ensures uniform results for installations requiring multiple identical openings. Designed for easy replacement in standard drill chucks, these bits offer practical handling for tiling, plumbing and light construction tasks involving glazed materials.

Suitable for

• Drilling glazed ceramic tiles in bathrooms and kitchens
• Creating holes in porcelain and other hard glazed surfaces
• Preparing openings for fixtures such as taps, pipes and anchors
• Repeated production or installation tasks requiring multiple identical holes

Key specifications

• Cutting tip: diamond-coated for improved hardness and wear resistance
• Diameter: 9.0 mm nominal cutting diameter
• Quantity: pack of 50 identical drill bits
• Compatibility: designed for standard drill chucks on handheld and bench drills
• Typical use: dry or with intermittent cooling to avoid overheating; requires controlled speed

How to use

Mark the drilling position on the glazed surface and secure the workpiece to prevent movement. Start at low speed to establish the hole and use light, steady pressure; do not force the bit. For best results, use intermittent drilling or a coolant such as water applied periodically to keep the tip cool and reduce glazing or cracking. Allow the bit to cool between prolonged drilling sequences and replace bits when wear affects hole quality.

Usage recommendations

Use protective eyewear and gloves when drilling glazed materials. Select a drill speed suitable for diamond-tipped bits and avoid hammer or impact modes. For larger or thicker tiles, consider gradual drilling with periodic cooling intervals to preserve the diamond tip and maintain hole precision.
