Diamond core drill bit GEKO 227x10x450 mm 18T 1.1/4" for wet and dry drilling

Diamond core drill bit GEKO 227x10x450 mm 18T 1.1/4" for wet and dry drilling is a precision tool for creating large-diameter holes in masonry, concrete, stone and similar hard materials. With a 227 mm cutting diameter, 10 mm segment height and overall length of 450 mm, this core bit is fitted with an 18T diamond segment arrangement and a 1.1/4" threaded connection for use with compatible core drilling rigs. It is designed to perform efficiently in both wet and dry drilling conditions, providing clean cores and reliable penetration when used according to machine and material guidelines.

Advantages

The GEKO diamond core drill bit combines a robust diamond segment construction with a standardized 1.1/4" connection, ensuring secure attachment to core drilling rigs and stable cutting performance. Its 18T segment layout is optimized for balanced cutting and wear distribution, while the 450 mm length allows for deep penetration and removal of sizeable cores. The ability to be used wet or dry increases versatility on site and reduces the need for multiple specialized bits.

Suitable for

• Drilling large-diameter holes in reinforced concrete and masonry
• Creating openings for plumbing and pipe installations
• Making passages for electrical and communication cables
• Core sampling and removal of material for inspection or retrofitting

Key specifications

• Cutting diameter: 227 mm
• Segment height: 10 mm
• Overall length: 450 mm
• Segment configuration: 18T diamond segments
• Connection type: 1.1/4" threaded
• Drilling modes: suitable for wet and dry drilling

How to use

Select a core drilling rig compatible with a 1.1/4" threaded bit and secure the GEKO core drill bit according to the machine manufacturer’s instructions. Mark the drilling location, ensure proper anchoring of the rig, and start drilling with steady axial pressure and controlled rotation speed. For wet drilling, supply water consistently to cool the diamond segments and to evacuate slurry; for dry drilling, use appropriate dust extraction and intermittent cutting to avoid overheating. Withdraw the bit periodically to clear the core and debris and to inspect segment wear.

Usage recommendations

Use the GEKO 227x10x450 mm core bit with compatible rigs rated for large-diameter drilling and follow safety guidelines for rotary core drilling. For longer tool life, prefer wet drilling where possible, avoid excessive lateral force, and replace the bit when cutting efficiency or segment height is noticeably reduced.
