Overview
The XT40 is the heavy-duty inner auger extension on a 100mm square hub, in 6, 8 and 10 foot lengths. The square drive is the significant part: at the torque these drives produce, a hex connection becomes the limiting component, which is why the whole 18–30 tonne range moves to square. It suits RC11 auger bits on the 20DDS through 30DDT drives and the SD Supa range — piling and deep drilling work.
Key Features of the XT40 Heavy Duty Auger Inner Extension
- Type: Inner extension, heavy duty
- Hub: 100mm square
- Lengths: 6ft, 8ft and 10ft
- Suits auger bits: RC11
- 100mm square hub, not hex — square drive is what transmits this level of torque without rounding out.
- Heavy duty construction for the 18–30 tonne drive range.
- 6, 8 and 10 foot lengths.
- Inner extension — the XO40 outer range is a separate part.
- Suits RC11 bits on 20DDS through 30DDT drives and the SD Supa range.
- Made in Dyersville, Iowa.
Why the XT40 Heavy Duty Inner Extension Earns Its Place
- Piling depth is what this range exists for, and depth is where extensions earn their place rather than being a convenience.
- Nothing from the hex ranges fits — XO20, XO25, XO30, XT25 all use hex hubs and none of them will connect to a square shaft.

What to Order Alongside the XT40 Heavy Duty Inner Extension

- RC11 auger bits on the matching 100mm square hub.
- A RYNO piling cradle hitch if the work is pile installation rather than drilling.
XT40 Heavy Duty Auger Inner Extension Questions, Answered
Why is this hub square rather than hex?
Torque. Above the 16DDS the range moves to a 100mm square shaft because a hex connection starts rounding out at the loads these drives produce. It is a structural decision, and it means nothing from the hex ranges interchanges.
Will my XO25 or XT25 extensions fit?
No. Those are hex-hub parts for the smaller drives. The 100mm square range — XO40 and XT40 — is entirely separate, and there is no adapter that makes a 2.5" hex extension carry this level of torque safely.
Why buy an extension rather than a longer auger?
Cost and transport. A longer auger is a single-purpose tool you carry on every job whether you need the depth or not. XT40 extensions stack in six, eight and ten foot increments, so one set covers several depths, and they travel flat instead of hanging off the machine. For occasional deep holes the extension wins comfortably.
Which bits does it suit?
RC11, which is Digga’s heavy-duty rock and earth combination auger for the 100mm square shaft.
How is shipping calculated?

How do I order?
Add the item to your cart and check out online — the order page asks for your machine make and model, so there is no need to call ahead. We check the mount against your machine after the order and come back to you if anything needs changing. If you would rather ask first, email support@eskidsteer.com or use the chat button on your screen.
Buyers find the XT40 Heavy Duty Inner Extension searching for a auger bit extension, a inner extension, or a piling auger bit to suit a machine they already run. It sits alongside digga auger and excavator auger bit in the same catalogue. All of it is genuine auger extensions equipment made in Dyersville, Iowa.
Worth being clear that this is a different class of part from the hex extensions further down the range. Nothing crosses over — not the hubs, not the pins, not the bits. If you are stepping up from a 16DDS to a 20DDS, the extension inventory does not come with you.
