Drill Bit Extension GEKO 40 cm 1 1/4" for Core Drill Bits

The GEKO Drill Bit Extension 40 cm 1 1/4" is an accessory designed to increase the working reach of compatible core drill bits. With a 40 cm length and a 1 1/4" connection size, this extension maintains alignment and torque transfer between the power tool and the core bit, enabling drilling in deeper or hard-to-reach areas without changing the primary drill setup.

Advantages

This extension provides additional length while preserving rotational stability and alignment for core drilling tasks. Its standardized 1 1/4" connection ensures compatibility with many core drill systems that accept this interface, reducing the need for adapters. The straight, rigid construction minimizes flex and helps maintain consistent torque transmission from the drill to the core bit, which supports cleaner holes and more controlled drilling progress.

Suitable for

• Extending reach for core drilling in concrete, masonry, and similar materials
• Drilling in ceilings, deep walls, and other hard-to-reach locations
• Renovation and construction tasks requiring extended bit access
• Scenarios where maintaining alignment and torque is essential

Key specifications

• Length: 40 cm
• Connection size: 1 1/4" (1.25")
• Function: Extension for core drill bits to increase working reach
• Design: Straight rigid extension to preserve alignment and torque transfer

How to use

Attach the extension between the core drill bit and the drill according to the connection interface, ensuring a secure, fully seated fit. Verify that any locking mechanisms or set screws are tightened as required by the drill system being used. Check alignment visually and by running the tool at low speed before full operation. Use appropriate feed pressure and coolant or water if the drilling application and material require it. After use, disconnect the extension and inspect the connection points for wear or damage.

Usage recommendations

Use the extension only with core drill bits and drills that match the 1 1/4" connection and that are rated for the additional cantilever load. Follow the drill and bit manufacturers' safety instructions, use appropriate personal protective equipment, and avoid excessive side loading to prevent premature wear or bending.
