Overview
The Digga AB4 is a bolt-on skid steer auger bit, and the bolt-on part is the whole point: its teeth fasten with a bolt and nut rather than being driven into a pocket with a pin. That makes a tooth change a spanner job on the tailgate instead of a hammer job, which matters when you are changing teeth often — abrasive ground, long shifts, or a crew without a press. It runs a 2" hex hub on the same drives as the A4.
Key Features of the Digga AB4 Auger Bit
- The AB4 ships on a 2" hex hub on this listing — the hub is what decides which Digga drives it fits
- 7 diameters available, from 9" to 36"
- Pin, clip, teeth and pilot included — no separate wear-part order needed to drill
- TRU-CUT geometry — the auger cuts its nominal diameter rather than an oversized hole you backfill with concrete
Why This AB4 Bit Earns Its Place
- Bolted teeth change with a spanner — no pin drift, no hammer, no press, and no lost TruLoc pins in the dirt.
- Three tooth options rather than two — plain earth, tungsten carbide, and hard-faced, so the head can be matched more finely to the ground.
- Same 2" hex hub as the A4, so it runs on the same drives and extensions with no adapter.
- Practical where teeth wear fast — if you are changing teeth weekly, the time saved on each change is the reason to buy this rather than a pinned head.

Every figure above comes from Digga’s published data sheet for the AB4. Teeth and pilot are consumable items and are replaceable individually.
Choosing Your AB4
The AB4 is ordered by the choices below; the head and body are the same in every one.

Diameter
- 9"
- 12"
- 14"
- 18"
- 24"
- 30"
- 36"
Diameter guidance: the AB4 runs 9" to 36". Choose Earth for general soil, Hard Ground for compacted and abrasive material.
Which Digga Drives Take the AB4?
Uses a 2" hex hub and fits Digga 1MDS through 4DSS drives and the 4DDS. XO20 extensions add depth. The A4 and RC4 share the same hub if you want a pinned-tooth head instead.
What Machine Do I Need?
The AB4 is an auger bit, not a machine attachment — it fits the auger drive, and the machine underneath is whatever runs that drive. It needs a Digga drive with a 2" hex output shaft — the 1MDS, 1DSS, 2DSS, 3DSS, 4DSS or 4DDS.
Add your drive model at checkout and we check the hub matches before the order ships. Stay within the maximum drilling diameter published for your drive and machine class.
Digga AB4 Auger Bit Questions, Answered
What is the advantage of bolt-on teeth?
Speed and simplicity of replacement. A bolted tooth comes off with a spanner; a pinned tooth needs a drift and a hammer, and the pin is easy to lose. If your ground eats teeth, the AB4 saves real time over a season.
Are the teeth and pilot included?
Yes. Every Digga auger bit ships with pin, clip, teeth and pilot fitted. All of those are consumable and replaceable individually, so a worn head is a wear-part order rather than a new bit.
What tooth options does the AB4 have?
Three: DP-40/50 plain earth teeth, DP-40/50C tungsten carbide, and DP-40/50HFF hard faced. All use the same DP-40/50CB bolt and DP-40/50N nut, with a PM-SQ-1 or PM-SQ-3 pilot depending on configuration.
Does a 12" auger really drill a 12" hole?
That is what Digga’s TRU-CUT head geometry is for. Many augers cut oversize, which means every hole gets backfilled with more concrete than the design called for. Holding the nominal diameter is a direct materials saving across a pier job.
How do I drill deeper than the bit length?
Digga XO20 extensions stack in one-foot increments, which is cheaper than buying a longer auger for occasional deep holes and easier to transport. They fit between the drive and the AB4.

Buyers find the AB4 searching for a earth auger bit, an auger teeth, or a specific size such as an auger bit 12 inch. It also comes up alongside skid steer auger when a worn head needs refreshing rather than replacing, and against bolt on auger bit when someone is choosing between bit families. The AB4, like the rest of the range, is genuine digga auger tooling made in Dyersville, Iowa.
