The Eterra Stinger Spiral Splitter transforms your auger into a powerful, high-efficiency log splitter. Its precision-engineered spiral design multiplies splitting force, reducing the effort and time required to split logs of varying sizes and densities. Ideal for firewood production or commercial log processing, it delivers consistent results while minimizing operator fatigue. Built for versatility, the Stinger allows quick conversion between a 2" Hex and a 2 9/16" Round shaft—just remove six heavy-duty bolts to adapt to different auger drives. Rugged construction ensures long service life, even in demanding wood-splitting applications. To perform at its best, the Stinger requires an auger capable of delivering at least 2,100 ft-lbs of torque, making it the choice for professionals who demand speed, strength, and adaptability.
