Review on EA8F Earthquake - 8 Inch Earth Diameter by Michael Caste

This drill was of the expected quality. It's on par with previous earthquake bits I've had. The fishtail tip is excellent for penetrating hard ground. The 8" bit is a lot more aggressive in the mud than the 6" bit I've used for years. Make sure you have a firm grip on the powerhead in case you catch a root and if you are a man make sure the tenders are not lined up with the powerhead. You're going to have a bad day with quickness if you catch a root and get hit in the tenders. Great, well made product. Great price and build quality.
