Hole Saw Drill Extension GEKO 50 cm 1 1/4" for core drilling

Extension shaft for hole saws by GEKO, designed to provide an additional 50 cm of reach with a 1 1/4" connection size. This extension allows the use of core and hole-saw drill bits at greater depths or in recessed and hard-to-reach locations while maintaining compatibility with arbors and drills that accept a 1 1/4" interface.

Advantages

The GEKO 50 cm extension shaft increases drilling reach without altering the cutting tool, enabling deeper core drilling and access to confined spaces. Its standardized 1 1/4" connection ensures compatibility with many hole saw arbors and accessories, while a straight, rigid shaft delivers stable guidance during drilling. The design focuses on maintaining concentric alignment between the hole saw and the drill to reduce wobble and improve cutting accuracy.

Suitable for

• Core drilling into walls, ceilings and floors where extra depth is required
• Installation tasks that require reaching behind structures or into cavities
• HVAC, plumbing and electrical work involving recessed fixtures or piping
• Construction and renovation jobs where standard-length arbors do not reach the drilling point

Key specifications

• Overall length: 50 cm
• Connection size: 1 1/4" (standard hole saw arbor interface)
• Designed use: extension for core / hole-saw drilling
• Compatibility: for tools and arbors accepting a 1 1/4" connection
• Function: provides additional reach for deeper or hard-to-reach drilling

How to use

Attach the extension shaft to a compatible 1 1/4" arbor according to the arbor manufacturer's instructions, then mount the chosen hole saw or core bit. Secure all connections and check for correct seating and alignment before operation. Use appropriate drilling speed and steady feed pressure to avoid binding; coolant or periodic retraction may be required depending on the material being cut. Inspect the shaft and connections for wear or damage before each use.

Usage recommendations

Use the extension with compatible arbors and follow safety guidance for hole-saw drilling: wear eye and hand protection, ensure the workpiece is secured, and choose drill speed appropriate to the material. Avoid excessive side loads and misalignment to prolong tool life and maintain cutting precision.
