Extension for NAC drill TTGD520 / model EAP52-295-T — accessory for drill bit reach extension

Extension for NAC drill TTGD520 (model EAP52-295-T) is a threaded accessory that increases the working reach of your drill by connecting between the drill chuck and the drill bit or core. Designed for use with compatible NAC threaded connections, this extension enables drilling at greater depths or in recessed and hard-to-reach locations without changing to longer bits. It is intended for construction, installation and maintenance tasks where extra reach improves access and productivity.

Advantages

The extension provides a secure threaded connection that preserves rotational alignment and torque transmission from the drill to the bit. By adding length without compromising stability, it reduces the need to handle long bits directly and allows continued use of standard bits to reach deeper points. The compact accessory is simple to fit and remove, keeping workflow efficient on site or during installation jobs.

Suitable for

• Drilling deeper holes in concrete, wood, or masonry where standard bits are too short
• Reaching recessed or obstructed drilling locations in walls or ceilings
• Installation and maintenance tasks that require extended bit reach without changing core tools
• Situations where using a single drill while adapting bit length is preferable to swapping tools

Key specifications

• Compatibility: fits NAC TTGD520 with matching threaded connections
• Function: extends working reach between drill and drill bit/core
• Connection type: threaded coupling designed for secure torque transfer
• Intended use: construction, installation and maintenance drilling applications
• Form factor: compact inline extension to minimize wobble and preserve alignment

How to use

Ensure the drill is powered off and disconnected from any power source before fitting the extension. Screw the extension securely into the drill’s threaded connection, then attach the chosen drill bit or core to the other end of the extension and tighten according to the bit manufacturer’s recommendations. Confirm that all threaded joints are properly seated and that the assembly runs true before starting work. Periodically check the connection during use and stop the drill before tightening if any loosening occurs.

Usage recommendations

Use the extension with bits and cores rated for the material and depth of the job. Avoid applying excessive side load or hammering forces through the extension; it is intended for rotary drilling and may not be suitable for impact or percussion modes unless explicitly supported by both the drill and the bit. Regularly inspect threaded connections for wear or damage and replace the extension if any deformation or excessive thread wear is observed.
