## Summary description

Diamond core drill bit GEKO 100 mm designed for drilling porcelain, gres and other hard ceramic materials. Professional segmented diamond edge provides efficient cutting and long life when used with water cooling. Suitable for creating clean 100 mm diameter holes for plumbing, ventilation, tile installation and electrical fixtures in hard tile surfaces.

## Long description

Diamond Core Drill Bit for Porcelain/Gres GEKO 100 mm is a segmented diamond-edge core bit designed for drilling through porcelain, gres and other hard ceramics. The 100 mm cutting diameter produces clean circular holes suitable for pipe passages, ventilation outlets, electrical mounting and tile penetrations. The bit is intended for use with water cooling and compatible rotary or drill rigs that accept core drill bits of this diameter.
Advantages
The GEKO 100 mm diamond core drill bit features a professional segmented diamond cutting edge that delivers efficient material removal and prolonged life when used with continuous water cooling. Its construction reduces chipping on fragile glazed surfaces and enables precise, round holes with minimal finishing. The design supports stable drilling at moderate speeds and helps control heat build-up to preserve diamond segments.
Suitable for
 Drilling 100 mm holes in porcelain and gres tiles
 Creating openings for plumbing pipes and fittings through tiled walls and floors
 Making circular penetrations for ventilation ducts and exhaust outlets
 Installing electrical boxes or conduit through hard ceramic surfaces
When it may not be suitable
This diamond core bit is optimized for hard ceramic materials such as porcelain and gres; it may not perform optimally on very soft materials like drywall, soft plastics, or untreated wood. It is not intended for dry drilling without adequate cooling—using it dry can cause rapid wear and overheating. For very thick concrete or reinforced concrete, a masonry or concrete-specific core bit may be more appropriate.
Key specifications
 Cutting diameter: 100 mm
 Suitable materials: porcelain, gres and similar hard ceramics
 Cutting edge: segmented diamond
 Recommended cooling: continuous water cooling
 Typical use: wet core drilling for clean circular holes
How to use
Secure the core drill bit in a compatible drill or core drilling rig following the tool manufacturer’s instructions. Mark the center point on the tile and start drilling at low speed to establish the pilot contact, applying light steady pressure. Maintain continuous water flow to cool the diamond segments and flush out slurry. Increase speed moderately once the cut is established, keeping the bit perpendicular to the surface. After completing the hole, stop the tool and allow the bit to cool before removing it from the machine.
What to consider before purchase
 Verify compatibility with your drill or core rig’s chuck and mounting method.
 Ensure you can provide continuous water cooling when drilling hard ceramics.
 Confirm that a 100 mm diameter hole is suitable for your plumbing, ventilation or electrical needs.
 Assess whether your project requires a diamond core bit rated for reinforced concrete or thicker materials.
Usage recommendations
Use steady, controlled pressure and continuous water cooling to maximise cutting life and minimise chipping on glazed tile surfaces. Start at low speed to centre the bit, and keep the drilling axis stable to achieve a clean 100 mm hole suitable for installations.
