## Summary description

Diamond core drill bit GEKO 140mm designed for cutting and drilling porcelain gres. This core bit features a diamond cutting edge for effective penetration in hard ceramic and gres surfaces. Suitable for creating 140 mm diameter holes in tiles for plumbing, electrical fixtures and installations where precise circular openings in gres are needed.

## Long description

The Diamond Core Drill Bit GEKO 140mm for Porcelain Gres is a purpose-built core bit designed to cut precise 140 mm circular openings in hard ceramic and gres tiles. It uses a diamond cutting edge to provide effective penetration and controlled cutting when installing plumbing, electrical fixtures or creating service access points in tile finishes. The tool is intended for use with compatible drill rigs or angle grinders equipped with a core bit adapter and appropriate cooling methods.
Advantages
The diamond-segmented rim ensures improved cutting performance on dense porcelain gres and ceramic surfaces while maintaining edge life under normal drilling conditions. Its 140 mm diameter delivers a consistent hole size for fixtures and pipe penetrations, reducing the need for manual finishing. The bit permits cleaner cuts compared with non-diamond alternatives and is suitable for wet cutting, which helps control dust and heat during operation.
Suitable for
Drilling 140 mm diameter holes in porcelain gres and dense ceramic tiles
Creating openings for plumbing pipes, drains and bathroom fittings
Preparing passages for electrical conduits and recessed fixtures
On-site tile modifications where precise circular holes are required
When it may not be suitable
This diamond core bit is optimized for hard ceramic and porcelain gres and may not perform as efficiently on very soft or highly porous materials such as quarry tiles, thin ceramic or laminate. It is also not suitable for drilling through very thick reinforced concrete or solid masonry where specialized core bits for concrete would be required. Proper power tool compatibility and cooling (wet drilling) are necessary to achieve expected life and cutting quality.
Key specifications
Cutting diameter: 140 mm
Suitable material: porcelain gres and hard ceramic tiles
Cutting edge type: diamond-segmented rim
Recommended use: wet drilling to reduce dust and heat
Typical applications: plumbing, electrical installation, tile openings
How to use
Secure the workpiece and mark the center of the required 140 mm hole. Mount the GEKO diamond core drill bit onto an appropriate drill or core rig using the correct adapter and ensure the tool is firmly clamped. For best results use wet drilling with a steady water feed to cool the diamond segments and suppress dust. Start drilling at low speed to establish the pilot groove, then increase speed and apply steady, even pressure. Avoid excessive force and allow the diamond segments to do the cutting. Periodically withdraw the bit to clear slurry and check progress until the hole is completed.
What to consider before purchase
Confirm the 140 mm diameter matches the required fixture or pipe size
Verify the bit is compatible with your drill or core rig and adapter
Plan for wet drilling or appropriate cooling to extend bit life
Ensure the target material is porcelain gres or a similarly hard ceramic
Usage recommendations
Use with a stable rig or guide to maintain perpendicularity, a continuous water feed for cooling, and appropriate personal protective equipment. Replace the bit when cutting performance degrades to avoid damaging tiles or fixtures.
