Compatibility / Fitment

Compatibility varies by product type, machine setup, selected options, and intended application.

For machine-mounted equipment and attachments, buyers should confirm fitment before ordering using the relevant machine information, including model, attachment style, mount type, coupler type, hydraulic requirements, and any other product-specific requirements listed on the page.

Hardscape Heavy can assist with pre-order fitment guidance based on the information you provide. This guidance is limited to purchase and compatibility review before ordering and does not include field installation, hydraulic modification, fabrication, or on-site setup support.

If you are unsure whether a product will work with your machine or application, contact us before placing the order.

Eterra's Earth Auger Bits are the bits fitted to an auger drive rather than the drive itself. They carry the same hex hub the rest of Eterra's auger accessory line uses, so the bits, the extensions and the other accessories in that line all mount to one interface.

Tooth count rises with diameter across the line. Eterra publishes no teeth at all on the smallest bit, which works on its pilot and flighting alone, while the larger diameters carry a full row of bolt-on teeth that are replaced individually as abrasive ground wears them.

Every bit ships with a carbon steel pilot point for general work, and a tungsten carbide fishtail pilot is offered as an upgrade for compacted or rocky ground. That upgrade is a cart selection rather than a separate listing, as are the optional carbide teeth.

All eight diameters are orderable through this listing. One of them carries Eterra's own published part number and the other seven are ordered against internal reference numbers, because Eterra publishes a part number for the 4 inch alone.

Common Applications

  • Auger drilling for fence and sign post holes
  • Digging tree and shrub planting holes
  • Footing and foundation holes
  • Utility and irrigation digging

Selection Notes

  • The cart requires an auger bit size selection and offers 4, 6, 9, 12, 18, 24, 30 and 36 in.
  • A tungsten carbide fishtail pilot is offered as an optional upgrade in the cart.
  • Optional tungsten carbide teeth are offered in the cart in even quantities from 2 to 24.
  • Neither optional selection is published with a figure on any Eterra surface, so neither is listed as a variant here.
  • All Eterra auger bits and accessories use a 2 in hex connection.
  • The published line weight range is 46 to 225 lb across all eight diameters.
