The Digga Auger Adapter makes it possible to connect an auger drive and auger bit that use different shaft or hub sizes. It’s a practical option if you already have a drive and bit you want to use together but the connections don’t match.

Each adapter option is listed in Drive → Auger Bit order, so you can match the first size to your auger drive, and the second size to your auger bit.

Features

Easy Drive-to-Bit Sizing: Select the adapter by matching the first size to your auger drive, and the second size to your auger bit.
Multiple Connection Options: Available for 2″, and 2.5″ hex connections, plus 2-9/16″ round.
Use Existing Auger Bits: Lets you connect an auger bit with a different hub size instead of replacing the bit.
Heavy-Duty Construction: Built for drilling applications where a secure connection between the drive and bit matters.
Cannot Be Reversed: Each adapter has a dedicated drive side and auger-bit side.
Pin and Clip Included: Includes retaining hardware for the adapter connection.
Works Beyond Digga Setups: Can be used with compatible auger drives and bits from other manufacturers when the shaft and hub sizes match.

Drive Side: Female connection
Auger Bit Side: Male connection
Connection Types: Hex and round
Included: Retaining pin and clip
Installation: Fits between the auger drive output shaft, and the auger bit hub
Direction: Drive → Adapter → Auger Bit
Reversible: No

How do I choose the correct adapter?

First, check the size and shape of the output shaft on your auger drive. Then, check the size and shape of the hub on your auger bit.

Each adapter option is listed in this order:

[Drive Size] → [Auger Bit Size]

For example, if your drive has a 2.5″ hex output shaft and your bit has a 2″ hex hub, choose:

2.5″ Hex Drive → 2″ Hex Bit

On the adapter itself, the drive side is the female end, and the bit side is the male end.

What do “female” and “male” mean on an auger adapter?

The female end is the socket-shaped end that fits over your auger drive’s output shaft. The male end goes into the hub on your auger bit.

Can I flip the adapter around?

No. These adapters are directional. The female end is made for the drive side and the male end is made for the auger-bit side.

Does the adapter change my hydraulic requirements?

No. Hydraulic flow and pressure requirements come from the auger drive. The adapter only changes the mechanical connection between the drive and auger bit.

Note: The Digga Auger Adapter does not mount directly to the machine. Compatibility depends on the auger drive, drive output shaft, auger bit hub, hydraulic requirements, and the adapter size selected.

Digga adapters are covered by a 1-year manufacturer warranty against defects in materials or workmanship.

Keep using the augers you already own.
An adapter can let you use an existing bit with a drive that has a different output shaft size.

Take the guesswork out of matching connections.
Once you know your drive shaft size and bit hub size, the adapter choice is straightforward.

Mix compatible drive and bit systems.
Hex and round conversions give you more flexibility when your drive and auger bit were not originally built with the same connection.

Avoid buying the wrong direction.
Listing each option as Drive → Auger Bit makes it clear which connection belongs on each side.

Excellent customer service,Justin answered all the questions I had about the tire handler. They offer unbeatable prices great quality product and fast shipping. Before buying the tire handler usually took us 3-4 hours to swap tires on our sprayer with the tire handler we did it in 1 hour and a lot safer
