Diamond core drill bit GEKO 122x10x450 mm 10T 1.1/4" for wet and dry drilling

Diamond core drill bit GEKO 122x10x450 mm 10T 1.1/4" for wet and dry drilling is a segmented diamond coring bit engineered for creating precise circular holes in concrete, masonry and other hard mineral materials. With an overall length of 450 mm and a cutting diameter of 122 mm, the bit features ten cutting segments and a 1.1/4" threaded connection compatible with standard core drilling rigs. It is designed to operate in both wet and dry conditions, providing a versatile solution for tasks that require accurate core removal and clean hole edges.

Advantages

The GEKO diamond core bit provides efficient cutting performance through its diamond-segmented rim and ten cutting segments that distribute wear evenly and help maintain cutting speed. Its 450 mm length allows for deeper penetration and core retrieval while the 1.1/4" connection ensures secure mounting to common core drilling machines. The ability to use the bit in wet and dry drilling modes offers flexibility on jobsites where water supply or electrical safety considerations vary.

Suitable for

• Drilling clean circular holes in reinforced and non-reinforced concrete
• Creating openings for plumbing pipes and sanitary installations
• Making cable and conduit penetrations for electrical installations
• Core sampling and removal in renovation and repair work

Key specifications

• Cutting diameter: 122 mm
• Coring depth / overall length: 450 mm
• Number of cutting segments: 10 (10T)
• Connection: 1.1/4" threaded
• Operating modes: wet and dry drilling
• Suitable materials: concrete, masonry and other hard mineral materials

How to use

Select an appropriate core drilling rig with a compatible 1.1/4" spindle or adapter, mount the diamond core bit securely and set the machine to the recommended speed for the work material. For wet drilling, provide a steady water feed to the cutting edge to cool the segments and remove debris; for dry drilling, use intermittent drilling and allow the bit to cool periodically to avoid overheating. Apply steady axial pressure without forcing the bit, and withdraw the core barrel occasionally to remove cut material and inspect the segment condition.

Usage recommendations

Use personal protective equipment (safety glasses, hearing protection and dust mask) and ensure the drilling machine is properly secured. For reinforced concrete, use lower speeds and consistent cooling. Replace the core bit if segments show excessive wear or damage to maintain cutting quality and operator safety.
