Eterra Auger Adapters are the parts that make a mismatched auger setup work. A drive with one output shaft type and a bit, extension or accessory with another do not join without one, and Eterra offers the combinations across 2 inch hex, 2 inch round and 2-9/16 inch round.

The input hub is drilled with multiple holes rather than a single position, which Eterra states is what lets it fit most auger drives. A buyer selects for the drive unit's output shaft type and matches it to the collar size the accessory needs.

Eterra names crack-resistant welds as the durability claim on this line. That joint is the part carrying every bit of torque the drive puts out, so it is where an adapter fails if it is going to.

Common Applications

  • Auger drilling with a bit whose shaft does not match the drive
  • Fitting auger extensions to a drive of a different shaft type
  • Running auger accessories across mixed equipment
  • Boring and digging with mixed-brand auger setups

Selection Notes

  • The cart requires an adapter connection selection and offers five combinations.
  • Select for the drive unit's output shaft type first, then match the collar size the accessory needs.
  • All five combinations are priced and listed here.
  • The published weight is 20 lb.
  • Availability is In-Stock.
