Meet the Earth Auger Bits
Exterra Earth Auger Bits deliver heavy-duty drilling performance for skid steers, mini skid steers, and compatible auger drive systems. Engineered with a robust 2-inch hex connection, these bits ensure a secure fit and efficient torque transfer, making tough digging tasks easier and more reliable.
Available in diameters from 4" to 36" and a standard 48" length, these auger bits handle up to 4,500 ft-lbs of torque. They’re perfect for fence post installation, tree planting, foundation work, and utility digging. Each bit includes a carbon steel pilot point for general-purpose digging, with an option for a tungsten carbide fishtail pilot to tackle compacted or rocky soils. The number of cutting teeth scales with bit size—from 0 on the 4-inch bit to 10 on the 36-inch model—with replacement teeth available for long-term performance.
Built for durability, precision, and versatility, Exterra Earth Auger Bits excel in soft dirt, clay, or rocky terrain—making them a trusted choice for professionals and contractors.
