Earth Auger Bits | Eterra

The Eterra Earth Auger Bits are built for heavy-duty drilling, delivering precision and durability for skid steers, mini skid steers, and other auger drive systems. Designed with a 2″ hex connection, these bits provide a secure fit and maximum torque transfer, handling tough digging conditions without slipping. Available in widths from 4″ to 36″ and a standard 48″ length, they are rated up to 4,500 ft-lbs of torque, making them ideal for fence post installation, tree planting, foundation work, and utility digging.

Each auger bit comes with a standard carbon steel pilot point, designed for general-purpose digging. Operators can upgrade to a tungsten carbide fishtail pilot, which provides better durability and cutting efficiency in compacted soils and rocky conditions. The number of cutting teeth increases with bit size, starting at 0 teeth for the 4″ bit and going up to 10 teeth on the 36″ model. Additional standard or tungsten carbide replacement teeth are available for purchase, ensuring long-term performance even in abrasive ground conditions. Whether working in soft dirt, clay, or rocky terrain, Eterra auger bits provide reliable, high-performance drilling for any job site.

Do not use Earth Auger Bits on solid surfaces like concrete or asphalt driveways. For solid surface conditions choose a specialized rock auger bit, offered here: Eterra Rock Auger Bit
