The Digga 2″ Hex Auger Extension adds drilling depth to compatible auger setups without requiring a different bit. It fits Digga A4 and RC4 auger bits and other compatible 2″ hex setups, with lengths from 2 to 8 feet so you can choose the extra reach needed for the job.
The heavy-duty welded hub and shaft are built to keep the connection tight and reduce unwanted movement while drilling. Each extension includes the pin and clip needed for installation and is rated for auger drives producing up to 5,000 ft-lb of torque.
What does an auger extension do?
An auger extension installs between the auger drive and the bit to give you additional drilling depth.
Which Digga auger bits does this extension fit?
The 2″ XO20 extension is designed for Digga A4 Earth and RC4 Combination Rock/Earth auger bits.
Can I use it with another brand of auger drive?
Yes, provided the drive and auger use compatible 2″ hex connections and the drive does not exceed the extension’s 5,000 ft-lb torque rating.
How much additional depth can I add?
Choose from 2′, 3′, 4′, 6′, or 8′ extensions depending on how much additional drilling depth your job requires.
Can I stack auger extensions?
Adding more extension length increases the load and leverage on the drilling setup. The complete setup needs to remain within the limits of the drive, machine, auger, and extension. For unusually deep drilling, verify the setup before ordering rather than assuming multiple extensions can be safely combined.
Does the extension include the connecting hardware?
Yes. A retaining pin and clip are included.
Will this work with the DR6 Rock Auger Bit?
Not with the standard DR6 configuration. The standard DR6 uses a 2.5″ hex hub and is paired with Digga’s heavier 2.5″ extension family.
How do I know if my auger drive can use this extension?
Check the drive’s output shaft and torque rating. It needs a compatible 2″ hex connection, and the drive should not exceed the extension’s 5,000 ft-lb maximum torque rating.
Note: The extension does not mount directly to the machine. Compatibility depends on the auger drive and bit being used. It is intended for 2″ hex drilling setups in the same general machine class as the Digga A4 and RC4.

Digga auger extensions are covered by a 1-year manufacturer warranty against defects in materials or workmanship.
Get deeper without buying another auger.
Add the extra reach you need while continuing to use your existing compatible A4 or RC4 bit.
Choose only as much extension as the job needs.
Five available lengths let you add anywhere from 2 to 8 feet of additional reach.
Keep the drilling connection solid.
The welded hub and shaft are designed to reduce excess movement between the drive, extension, and auger bit.
Use it with more than just Digga drives.
A compatible 2″ hex drive from another manufacturer can use the extension as long as the connection and torque rating are appropriate.
