Description
Genuine Digga auger bit
Includes pin, clip, teeth and pilot
Overview
The Digga DR11 is a dedicated rock auger bit fitted with rotating carbide picks, built for fracturable rock, shale and permafrost rather than for soil. It runs a 4 inch square (100mm) hub, with a 3 inch hex hub available as an option, suits Digga 20DDS through 30DDS, and the SD range drives, and is sold here in six diameters from 12 to 36 inches on a 4 inch square hub. Every bit comes with its pin, clip, teeth and pilot fitted.
Key Features of the Digga DR11 Auger Bit
- Dedicated rock, shale and permafrost — the condition Digga builds this bit for
- 4 inch square (100mm) hub, or 3 inch hex as an option
- 80 in overall length on a 4.5 - 5.5 in pipe
- Flights 1 in lead and 3/4 in carry
- 1 inch rotating rock picks, with the DP-UAPC31-SA
- Maximum diameter 60 in in the Digga range
- Suits 20DDS through 30DDS, and the SD range drives
- True Cut design — Digga builds these bits so a 12 inch auger drills a 12 inch hole rather than an oversized one
- Supplied complete with pin, clip, teeth and pilot

Optimum Drilling Speed for the DR11
| Ground | Drill speed (RPM) |
|---|---|
| Earth | Not suited |
| Clay | Not suited |
| Shale / fracturable rock | 25-45 |
| Heavy rock | 10-25 |
Digga publishes these speeds because running a bit too fast in hard ground wears teeth without cutting. If your drive has a two-speed shift, this table is what the low range is for.
Which Drives Fit the DR11?
Fitment is set by the hub, not the machine. The DR11 has a 4 inch square (100mm) hub, which matches the output shaft on Digga 20DDS through 30DDS, and the SD range drives. A 3 inch hex hub is available if your drive uses that shaft. Where a drive and bit do not match, auger adapters convert between hub sizes, and auger extensions add depth below the bit. On this page the hub option reads 4" Square Hub.
Where the DR11 Sits Against Digga's Other Bits
- The DR11 is the rock bit — rotating carbide picks, short flighting, and no published speed for earth or clay because that is not what it is for.
- A combination bit (RC11) is faster and cleaner in mixed ground, and still rips fracturable rock.
- Picks are wear parts — short flighting is deliberate, so spoil clears and the picks can be inspected between holes.
On delivery: check the bit before you sign, and note any damage on the delivery receipt at the time of delivery. Photograph anything that looks wrong and email support@eskidsteer.com.
Digga DR11 Auger Bit Questions, Answered
What size DR11 do I need?
Match the diameter to the hole, not to the drive — then check the drive can turn it. Digga rates each drive to a maximum diameter in earth and a smaller one in clay or shale, and those figures are on the drive listings. The DR11 is offered in six diameters from 12 to 36 inches.
Can I use the DR11 in soil?
You can, but it is the wrong tool. Digga does not publish an earth or clay speed for this bit, because rotating rock picks are built to fracture rock rather than shear soil. In soft ground a combination bit cuts faster and leaves a cleaner hole.
Will the DR11 fit my auger drive?
If your drive has a 4 inch square (100mm) output shaft, yes — that covers Digga 20DDS through 30DDS, and the SD range. For a different shaft, auger adapters step between hub sizes, though an adapter adds length and a joint, so a matched hub is better where you have the choice.
Are teeth and pilot included?
Yes. Every Digga bit ships with pin, clip, teeth and pilot fitted. Teeth and pilots are wear parts, so they are also sold separately — for this bit, the 1 inch rotating rock picks and the DP-UAPC31-SA.
How deep can I drill?
The DR11 is 80 in overall, and the drive adds its own length above it. To go deeper, auger extensions fit between the drive and the bit. Two shorter extensions are usually more practical than one long one, because the whole stack has to be lifted clear of the hole.
When do teeth need changing?
When the cutting edge has worn back and the bit slows or starts wandering. Replacing teeth is far cheaper than wearing into the pockets or the flights, which are the expensive parts of the bit.
