## Summary description

Extension for a core (hole saw) drill bit by GEKO, length 20 cm with 1¼" (1.25 inch) connection. Designed to extend reach when drilling with coring or diamond core bits, enabling deeper holes in masonry, concrete or similar materials.

## Long description

Extension for a core (hole saw) drill bit by GEKO with a 20 cm length and a 1¼" (1.25 inch) connection. This accessory increases the working reach of diamond core and coring drill bits, allowing deeper holes in concrete, masonry and similar materials. It is intended to be used with compatible core drilling systems to access hard-to-reach locations or to extend the effective cutting depth without changing the drill bit.
Advantages
The extension offers stable, straight connection between the drill and core bit thanks to its standardized 1¼" coupling, reducing wobble during coring. Its 20 cm length provides additional reach for deeper penetration into walls, floors or other structures while keeping the drill at a safe distance from the work surface. The design is compact and simple, making it easy to attach and detach when switching bits or adjusting the drilling setup.
Suitable for
 Extending reach when drilling with diamond core bits in concrete and reinforced masonry
 Installation and renovation tasks where deeper through-holes are required
 Plumbing and electrical installations requiring holes through walls or floors
 Construction and repair jobs where the drill body must remain clear of obstructed areas
Key specifications
 Length: 20 cm
 Connection type: 1¼" (1.25 inch) male/female core bit coupling
 Intended use: extension for coring and diamond core drill bits
 Material compatibility: suitable for use when drilling masonry, concrete and similar hard substrates
 Compatibility: designed for core drilling systems that accept a 1¼" connection
How to use
Attach the extension to the drill spindle or adapter according to your core drilling system’s instructions, then connect the diamond core or coring bit to the opposite end of the extension. Ensure both connections are tightened securely to minimize runout. When drilling, maintain steady feed pressure and alignment to avoid side loads on the extension and bit. Use appropriate cooling or flushing methods recommended for the core bit in use, and check connections periodically during extended drilling operations.
Usage recommendations
Use the extension only with core drilling equipment rated for the intended substrate and bit type. Inspect the coupling surfaces for wear or damage before each use and replace the extension if any deformation is detected. Follow safety guidelines for coring operations: wear eye protection, hearing protection and dust control measures when drilling concrete or masonry.
